    <content type="html">&lt;p&gt;Last Sunday, my alarm rang with a musical note, I turned it off and saw it’s 4:15 in the morning. Excited, I woke up at the very first sound of it. It was my first test of endurance on a bicycle. I quickly got ready, packed my bag and opened google map to confirm the route I will be following - and the journey started - 5:30 a.m.&lt;/p&gt;

&lt;div align=&quot;center&quot;&gt;&lt;table class=&quot;map&quot;&gt;
  &lt;caption align=&quot;bottom&quot;&gt;Route to Nandi Hills, round trip distance - 140 km&lt;/caption&gt;
  &lt;tr&gt;
    &lt;td&gt;&lt;iframe src=&quot;https://www.google.com/maps/embed?pb=!1m34!1m12!1m3!1d267181.29474123695!2d77.36251934132298!3d13.155823622984464!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!4m19!3e0!4m5!1s0x3bae14067cca9bdd%3A0x111bbe37cc24e71a!2sThe+Leela+Palace%2C+Bengaluru%2C+Karnataka!3m2!1d12.960146!2d77.648496!4m5!1s0x3bae16356906d16d%3A0x13be180806d255b7!2sPalace+Ground%2C+Jayamahal%2C+Bengaluru%2C+Karnataka!3m2!1d13.01029!2d77.583947!4m5!1s0x3bb1e445ebfcea17%3A0x1639f72959196608!2sNandi+Hills%2C+Karnataka!3m2!1d13.370154!2d77.6834551!5e0!3m2!1sen!2sin!4v1481320151465&quot; width=&quot;600&quot; height=&quot;450&quot; frameborder=&quot;0&quot; style=&quot;border:0&quot; allowfullscreen&gt;&lt;/iframe&gt;&lt;/td&gt;
  &lt;/tr&gt;
&lt;/table&gt;&lt;/div&gt;


&lt;p&gt;It was still dark, shops closed and the roads belonged to just one being - &lt;em&gt;dogs&lt;/em&gt;. Safety was the number one thought on my mind. However, after a while, I started thinking, &lt;em&gt;&amp;ldquo;when was the last time I rode a bicycle?&amp;rdquo;&lt;/em&gt;. It happened to be close to 5 years ago and the effect was clearly visible. I found myself searching for motorcycle controls sub-consciously. I accidently pressed the gear button twice thinking of horn and indicator lights. While crossing a gas station came, I almost entered there thinking of refueling the tank. At every traffic signal, flyover I was thinking, how easy it felt to zoom past these on a motorcycle. But slowly, I started appreciating these hardships. It was because of the bicycle, I realized the importance of energy conservation. I preferred to slow down instead of applying brakes, especially at the signals.&lt;/p&gt;

&lt;p&gt;At around 6:30 a.m, I reached Hebbal flyover. I took a short break, drank some aloe-vera juice which I prepared at home (a big mistake). Feeling refreshed, I started again and went over the awesome expressway flyover. Soon, the aloe-vera juice did its job. I started looking for toilets on top of the flyover. I realized, the stretch of the flyover was many kilometers long before it actually touches the ground. With no option in sight, I continued riding. I was thinking, it is not easy for an amateur like me. I should probably, back off. Finally, the flyover ended at Yelahanka. I searched for available options as the shops were still closed. A security guard was very kind to guide me to a nearby Sulabh International.&lt;/p&gt;

&lt;p&gt;At 7:40 a.m, I was a little tired. I took a tea break and continued my journey. To distract myself from the pain, I started looking at the scenery. It was refreshing. I reached halfway at around 8:30 a.m. This boosted my confidence and now I was determined to complete the mission. I pushed myself over numerous mighty flyovers. At last, the highway ended and I was excited to ride on the lush green Nandi Hills road. At around 10:30 a.m, the destination was another 11 km away. Feeling very tired, I took another break. This time, it took me a while to re-assure myself that I can do it. I gently crossed the Nandi Hills traffic check post, 7 km uphill track remained. At 11:50 a.m, 5 km remained. I started struggling and it took around 20 mins for the next 1 km stretch. There was a small roadside stall with few snacks and tender coconuts. Tired and hungry, I had some light breakfast and met few cyclists - Prateek &amp;amp; Abhijit.&lt;/p&gt;

&lt;p&gt;After refueling and energizing myself, I continued the journey. The roads were steep, sometimes scary due to loose gravels as well. Finally, I made it at 1:12 pm. It was really satisfying to see the gates of Nandi Hills. Mission accomplished :D&lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;When my legs hurt, I say: &amp;ldquo;Shut up legs! Do what I tell you to do!&amp;rdquo; – Jens Voigt&lt;/p&gt;&lt;/blockquote&gt;

&lt;table class=&quot;image&quot;&gt;
  &lt;caption align=&quot;bottom&quot;&gt;Hair pin curves at Nandi Hills&lt;/caption&gt;
  &lt;tr&gt;
    &lt;td&gt;&lt;img style=&quot;margin-bottom: 0px&quot; src=&quot;/res/posts/the-pedal-stroke-it-never-gets-easier-you-just-get-faster/hair-pin-at-nandi-hills.jpg&quot; alt=&quot;Hair pin curves at Nandi Hills&quot;/&gt;&lt;/td&gt;
  &lt;/tr&gt;
&lt;/table&gt;


&lt;p&gt;I had some chat with my new cyclist friends. We had a brief photo session and then decided to travel back together. Riding downhill was amazing and super easy. We overtook many motorcycles, cars slowed us down as the road was not wide enough to overtake them. Riding back to Bangalore was easier than I thought. It is at a lower elevation. However, to keep up with my new friends, I stretched a lot without breaks. At one point, just before the airport flyover, I was completely exhausted. We took a small break and continued till the next food outlet - McDonald&amp;rsquo;s. They planned to go on a different route from there. I bid them goodbye, it was 4 p.m.&lt;/p&gt;

&lt;p&gt;Completely exhausted, I decided to take a big 30-40 mins break. My full lower body was paining like hell. I had the first real meal of the day and made a few phone calls. It was relaxing. I decided to start again at 4:40 p.m, around 35 km to go. Slowly and steadily, I continued my journey and reached home at 7 p.m.&lt;/p&gt;

&lt;div style=&quot;position: relative; padding-bottom: 81%; height: 0; overflow: hidden;&quot;&gt;&lt;iframe id=&quot;iframe&quot; src=&quot;/photos/album/endurance-to-nandi-hills/gallery/&quot; scrolling=&quot;no&quot; frameborder=&quot;0&quot;style=&#39;width:100%; height:100%; position: absolute; top:0; left:0;&#39; &gt;&lt;/iframe&gt;&lt;/div&gt;


&lt;p&gt;&lt;br /&gt;&lt;/p&gt;

&lt;p&gt;Looking back, I realize, I made a few mistakes:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Carried too much luggage - 2.5-liter water, eatables, camera, headphones, first aid, etc. I ended up emptying my bottles on the road to reduce weight. It&amp;rsquo;s advisable to carry as little as possible. Most cyclists carry  just a bottle of water/electrolyte drink along with few eatables like biscuits.&lt;/li&gt;
&lt;li&gt;Aloe-vera juice is not an alternative to an electrolyte drink. Coconut water is best.&lt;/li&gt;
&lt;li&gt;Mountain bike (MTB) is not suitable for highway tours.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Finally, thanks &lt;a href=&quot;https://twitter.com/krishnaghatti&quot;&gt;@krishnaghatti&lt;/a&gt; for lending your bicycle to me. You are awesome. &lt;strong&gt;And as always, Thanks for reading :-)&lt;/strong&gt;&lt;/p&gt;

    <title>29 questions to ask yourself if you’re in devops</title>
    <link href="https://www.rohit.io/blog/29-questions-to-ask-yourself-if-you-are-in-devops.html"/>
    <updated>2015-07-10T20:10:00+05:30</updated>
    <id>https://www.rohit.io/blog/29-questions-to-ask-yourself-if-you-are-in-devops</id>
    <content type="html">&lt;p&gt;A few days ago, I had an opportunity to meet and interact with &lt;a href=&quot;https://github.com/cachedout&quot;&gt;Mike Place&lt;/a&gt;, who works as a developer at &lt;a href=&quot;https://saltstack.com/&quot;&gt;Saltstack&lt;/a&gt;. We had an interesting conversation about devops and how things work in the valley. Mike explained the growing importance of devops in organizations and the rise of devops as a culture that aims to collaboratively deliver systems into production, reliably and effectively.&lt;/p&gt;

&lt;p&gt;He said &lt;em&gt;“Businesses are ever-changing. Engineers ship code, dozens of times each day. Every change in production has some probability of failure and business can get impacted due to that very failure. Risk is a combination of both of them. If only one of them is high, the risk may still be low. But if both of them are high, it can be a disaster. &lt;strong&gt;The role of devops is to minimize the risk of every change.&lt;/strong&gt;”&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;He asked a series of questions to self-evaluate the health of the devops team in any organization. The questions are an eye opener to every devops engineer.&lt;/p&gt;

&lt;p&gt;Here are 29 questions that you need to ask yourself if you are in devops. Go ahead and rate yourself on a scale of 1 to 5.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;Do you automate everything that can be automated and makes sense to automate?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;How easy is it to revert the changes?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you use role based configuration management?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you automate the creation of base system configuration (like OS installation, launching VMs, etc.)?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Is all your code stored in some version control system, viz. Git, mercurial, svn?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Does everyone (developers, devops, QA, etc.) in your organization knows where to look for code?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Can you build your code in ONE step? (5 points for one step build, -n if number of steps n is greater than 1)&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Can you deploy your code in ONE step? (5 points for one step deploy, -n if number of steps n is greater than 1)&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you have audited log for every deployment?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you release frequent small changes or club smaller changes into a big one to release less frequently?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you always ship master or feature branches?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you use feature flags to enable or disable a feature?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you do private beta releases?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you use AB Testing?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you do dark Launches?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you have metrics shared between Dev and Ops?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you have Application level metrics?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you co-relate application and system metrics?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you make changes based on the application or system metrics?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you have notifications based on metrics?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you have respect for other teams?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you stereotype others?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;How hard it is to say YES?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Does your team hide things?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;How often Dev talks about the impact with Ops?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Does Dev and Ops maintain checklist or plans?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Does Dev have access to production?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Do you practice fire drills?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Are there developers on call rotations?&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;What&amp;rsquo;s your score? Don&amp;rsquo;t worry, you don&amp;rsquo;t need to share it. It&amp;rsquo;s more important to ask yourself these questions often than focusing only on the answers.&lt;/p&gt;

&lt;p&gt;Should you need any clarification regarding these questions, don’t hesitate to comment below. &lt;strong&gt;And as always, Thanks for reading :-)&lt;/strong&gt;&lt;/p&gt;

&lt;h1&gt;Tech Talks on Ansible&lt;/h1&gt;

&lt;p&gt;We had 5 sessions which covered Introduction to Ansible, advanced topics as well as contributing to Ansible.&lt;/p&gt;

&lt;h3&gt;Getting started with Ansible-playbook&lt;/h3&gt;

&lt;hr /&gt;

&lt;p&gt;&lt;img src=&quot;/res/posts/ansible-meetup-knowlarity/images/ravdeep.jpg&quot; width=&quot;50%&quot; height=&quot;50%&quot; align=&quot;right&quot;&gt;&lt;/p&gt;

&lt;strong&gt;Summary&lt;/strong&gt;: In this talk, Aditya showed a complete end to end automation of an application using Ansible. The application was a Django website. The application was deployed with nginx, wsgi (running under gunicorn) and SQLite database. The application was deployed from scratch in less than 5 mins. The source code of the demo application is in his &lt;a href=&quot;https://github.com/adityak2190/sitedeploy&quot;&gt;github repository&lt;/a&gt;.&lt;/p&gt;

&lt;h3&gt;Running Ansible via API&lt;/h3&gt;

&lt;strong&gt;Summary&lt;/strong&gt;: In this talk, Hussain demonstrated how to use Ansible as a python library and expose custom APIs. His project used python flask to expose web APIs which was called from a remote server. The remote server had a beautiful WebUI built using bootstrap and javascript. The architecture was discussed in detail.&lt;/p&gt;

&lt;h3&gt;AWS Management with Ansible&lt;/h3&gt;

&lt;hr /&gt;

&lt;strong&gt;Summary&lt;/strong&gt;:  In this talk, I did a demo of Ansible cloud modules - AWS EC2 and Route53. The talk started with a quick introduction to AWS followed by a live demo. In the demo, I uploaded my public ssh key into AWS EC2, created a security group, launched two WordPress instances, created an ELB, register the newly created instances behind ELB and added an entry in Route53 nameserver. It demonstrated the power of Ansible to manage public clouds and define infrastructure in the form of simple YAML files.&lt;/p&gt;

&lt;h3&gt;Contributing to Ansible&lt;/h3&gt;

&lt;hr /&gt;

&lt;p&gt;&lt;img src=&quot;/res/posts/ansible-meetup-knowlarity/images/deepak.jpg&quot; width=&quot;50%&quot; height=&quot;50%&quot; align=&quot;right&quot;&gt;&lt;/p&gt;

&lt;strong&gt;Summary&lt;/strong&gt;: In this talk, Deepak talked about writing custom Ansible modules. The talk started with a quick introduction to key concepts and then focused more on code structure. The demo highlighted the coding structure of Ansible project, while keeping it simple. His demo module is hosted in his &lt;a href=&quot;https://github.com/hellodk/ansible-meetup-bangalore&quot;&gt;github repository&lt;/a&gt;&lt;/p&gt;

&lt;h3&gt;Say Cheers!&lt;/h3&gt;

    <title>RIP Nagios. Hello Docker Shinken!</title>
    <link href="https://www.rohit.io/blog/rip-nagios-hello-docker-shinken.html"/>
    <updated>2014-12-18T18:00:00+05:30</updated>
    <id>https://www.rohit.io/blog/rip-nagios-hello-docker-shinken</id>
    <content type="html">&lt;p&gt;Nagios is a great IT infrastructure monitoring tool. Some people still consider it as an IT standard for monitoring. But as with any software, there is always competition. I personally find Shinken to be one of the most compatible, modern and dare I say, a better alternative to Nagios. In this post, I will do a quick comparison between the two tools, show you reasons to migrate and more importantly how to migrate your current Nagios setup to Shinken in less than 10 minutes! No, seriously!&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Quick Introduction to Shinken&lt;/strong&gt;: Shinken was written by &lt;a href=&quot;https://twitter.com/naparuba&quot;&gt;Jean Gabès&lt;/a&gt; as a proof of concept for a new Nagios architecture. He proposed it as the new development branch of Nagios 4. When this proposal was turned down by Nagios authors, Shinken became an independent network monitoring software application compatible with Nagios. Shinken is basically a Nagios Core replacement written in python.&lt;/p&gt;

&lt;h1&gt;Shinken vs Nagios:&lt;/h1&gt;

&lt;p&gt;At &lt;a href=&quot;https://www.knowlarity.com/&quot;&gt;Knowlarity&lt;/a&gt;, we did the big switch from Nagios to Shinken for our complete infrastructure in just about a week. Having used both Nagios and Shinken now, I can tell you how Shinken has helped solve some of the fundamental problems which we faced using Nagios.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Reliability&lt;/strong&gt;: I was working on a NRPE notification plugin and deployed it in Nagios. I turned down a service to test it, but to my surprise Nagios was showing the status as OK (green). The last executed time got updated in the UI but nothing happened under the hood. It was a random issue and I suspect it could have been because of a old version of Nagios 3.x. I have been using Shinken for a while now (even before the migration in Knowlarity), and I have never once faced these sort of issues. The UI always displays the truth.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Active Development&lt;/strong&gt;: I updated Nagios to the latest 4.x. The first impression was that nothing had changed except for the colors in the user interface. In contrast, the complete architecture of Shinken 2.0 has been revamped. It has a modular design, and easy installation, and configuration features. Kudos to the Shinken community.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Multi DC deployment&lt;/strong&gt;: At Knowlarity, we have data-centers in multiple cities across multiple countries. It is a known fact that multi-DC deployment using Nagios is first of all difficult, and looks like a hack when deployed. In comparison, Shinken’s distributed architecture is amazingly simple. All of Shinken’s configuration is still managed in a single place. Here you just add a new shinken-poller in all your data centers and voila, you’re done.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Performance&lt;/strong&gt;: Nagios is written in C and is a lot faster than Shinken. However, Shinken has some exciting performance improvement modules like &lt;a href=&quot;https://github.com/shinken-monitoring/mod-booster-nrpe&quot;&gt;booster-nrpe&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Modern&lt;/strong&gt;: As opposed to Nagios tired old features, Shinken has support for dynamic configuration, AWS hosts, a module installer and many more rich support features. The Shinken community is very active and responsive.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;User Interface&lt;/strong&gt;: The Nagios UI, albeit old, is very feature rich. Shinken has a sleek and modern interface - WebUI. WebUI is really easy to use but lack features. However, there are many third party interfaces available. I like to use WebUI and &lt;a href=&quot;http://www.thruk.org/&quot;&gt;Thruk&lt;/a&gt; at the same time. Thruk interface is similar to that of Nagios. So hardcore Nagios users will still feel at home.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Easy Switch&lt;/strong&gt;: Probably the best thing about shinken is that it is like a plug and play replacement of Nagios core. Almost 100% compatible. Just dump your Nagios configuration in Shinken and it works. Take a look at their documentation for more details: &lt;a href=&quot;http://shinken.readthedocs.org/en/latest/01_about/whatsnew.html&quot;&gt;Feature comparison between Shinken and Nagios&lt;/a&gt;&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;h1&gt;Switch to Shinken in 3 easy steps:&lt;/h1&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;Install &lt;a href=&quot;https://docs.docker.com/installation/#installation&quot;&gt;docker&lt;/a&gt;. Select and pull one of the following docker image:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Shinken&lt;/strong&gt;: It has basic shinken installation along with few must have modules like WebUI (Web Interface), standard nrpe plugins plus a few extra ones, nrpe-booster support and a lightweight web server (nginx). Link: &lt;a href=&quot;https://registry.hub.docker.com/u/rohit01/shinken/&quot;&gt;https://registry.hub.docker.com/u/rohit01/shinken/&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Shinken Thruk&lt;/strong&gt;: Shinken (as written above) + Thruk web interface. Internal web server nginx is replaced with apache2. Link: &lt;a href=&quot;https://registry.hub.docker.com/u/rohit01/shinken_thruk/&quot;&gt;https://registry.hub.docker.com/u/rohit01/shinken_thruk/&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Shinken Thruk Graphite&lt;/strong&gt;: Shinken Thruk (as written above) + graph support in WebUI. Graphs are stored and served using graphite. Retention is configured for 1 month on a per 2 minute basis. Link: &lt;a href=&quot;https://registry.hub.docker.com/u/rohit01/shinken_thruk_graphite/&quot;&gt;https://registry.hub.docker.com/u/rohit01/shinken_thruk_graphite/&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt; Sample execution: &lt;code&gt;$ sudo docker pull rohit01/shinken&lt;/code&gt;&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Clone project &lt;strong&gt;&lt;a href=&quot;https://github.com/rohit01/docker_shinken&quot;&gt;docker_shinken&lt;/a&gt;&lt;/strong&gt;. You will see three directories corresponding to the docker images mentioned above. Go inside the directory corresponding to your selected image. You will see a directory named: &lt;a href=&quot;https://github.com/rohit01/docker_shinken/tree/master/shinken_basic/custom_configs&quot;&gt;custom_configs/&lt;/a&gt;. Dump your Nagios configuration here. A default configuration for monitoring docker host is already defined. User login details can be updated in file: &lt;a href=&quot;https://github.com/rohit01/docker_shinken/blob/master/shinken_basic/custom_configs/htpasswd.users&quot;&gt;htpasswd.users&lt;/a&gt;. File contains the documentation in comments.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Run the docker image. Expose TCP port 80 to the base machine and mount custom_configs directory to /etc/shinken/custom_configs. Sample execution:&lt;/p&gt;

&lt;pre&gt;&lt;code class=&quot;`&quot;&gt; $ git clone https://github.com/rohit01/docker_shinken.git
 $ cd docker_shinken/shinken_basic
 $ sudo docker run -d -v &quot;$(pwd)/custom_configs:/etc/shinken/custom_configs&quot; -p 80:80 rohit01/shinken
&lt;/code&gt;&lt;/pre&gt;&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Open your browser and visit these urls (Default credential - admin/admin):&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;strong&gt;WebUI&lt;/strong&gt;: &lt;a href=&quot;http://localhost/&quot;&gt;http://localhost/&lt;/a&gt;. Available on all three images.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Thruk UI&lt;/strong&gt;: &lt;a href=&quot;http://localhost/thruk/&quot;&gt;http://localhost/thruk/&lt;/a&gt;. Available on shinken_thruk and shinken_thruk_graphite images.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Graphs&lt;/strong&gt;: &lt;a href=&quot;http://localhost/service/docker_shinken/http_port_7770#graphs&quot;&gt;http://localhost/service/docker_shinken/http_port_7770#graphs&lt;/a&gt;. Available only on shinken_thruk_graphite image.&lt;/li&gt;
&lt;/ol&gt;


&lt;h3&gt;Please Note:&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Configuration changes are required only in one place/directory: custom_configs&lt;/li&gt;
&lt;li&gt;The nrpe plugins installation directory is /usr/lib/nagios/plugins.&lt;/li&gt;
&lt;li&gt;If you are using custom NRPE plugins, mount your plugins directory inside docker container at /usr/local/custom_plugins. Modify the resource path accordingly.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;If you have any question, I will be happy to answer them in comments. &lt;strong&gt;And as always, Thanks for reading :)&lt;/strong&gt;&lt;/p&gt;

    <title>Why static blog site is a good idea!</title>
    <link href="https://www.rohit.io/blog/why-static-blog-site-is-a-good-idea.html"/>
    <updated>2014-12-08T20:40:00+05:30</updated>
    <id>https://www.rohit.io/blog/why-static-blog-site-is-a-good-idea</id>
    <content type="html">&lt;p&gt;Starting a blog is fairly easy. There are many free blog hosting providers in the internet. However, each of them has some limitation on the level of customization. So, I decided to host it myself and figure out the best alternative.&lt;/p&gt;

&lt;h1&gt;First Steps&lt;/h1&gt;

&lt;p&gt;These were the first steps, I took while starting my blog - &lt;a href=&quot;http://www.rohit.io&quot;&gt;Simplicity&lt;/a&gt;:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Domain&lt;/strong&gt;: Domain is the most important identity of a blog. Free domains are mostly bound to a hosting provider and help them more than the owner. So, I decided to get a personal domain - &lt;a href=&quot;http://www.rohit.io&quot;&gt;rohit.io&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Static vs Dynamic&lt;/strong&gt;: Personal blogs are mostly static. Only blog posts get added every few days and comments by visitors. So, I decided to go with a static website generator - &lt;a href=&quot;http://jekyllrb.com/&quot;&gt;Jekyll&lt;/a&gt;. For comments, I added the &lt;a href=&quot;https://disqus.com/&quot;&gt;Disqus&lt;/a&gt; plugin.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Hosting provider&lt;/strong&gt;: Github has support for hosting Jekyll websites. Plus, it&amp;rsquo;s highly reliable, zero maintenance and free. Problem solved!&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Design&lt;/strong&gt;: The inbuilt theme of Jekyll is very basic. I searched few Jekyll websites and decide to reuse this one: &lt;a href=&quot;http://rsms.me&quot;&gt;http://rsms.me&lt;/a&gt; / &lt;a href=&quot;https://github.com/rsms/rsms.github.com&quot;&gt;https://github.com/rsms/rsms.github.com&lt;/a&gt;. Source code was under creative commons license (friendly).&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Search&lt;/strong&gt;: &lt;a href=&quot;https://www.google.co.in/cse/&quot;&gt;Google custom search engine&lt;/a&gt; was already configured in the code. I updated the same to point to &lt;a href=&quot;http://www.rohit.io&quot;&gt;Simplicity&lt;/a&gt; blog.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Google Analytics&lt;/strong&gt;: This was, again, already configured in the code. Updated the same with the ID generated for &lt;a href=&quot;http://www.rohit.io&quot;&gt;Simplicity&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;


&lt;h1&gt;Next Steps&lt;/h1&gt;

&lt;p&gt;I had a decent blog site. However, there were some unsolved problems like SEO, social plugins, link share previews, etc. Since, the website source code was not mine, it was difficult to fix. I did a complete revamp of the website to fix this. Post this, I was able to solve the following problems:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;SEO&lt;/strong&gt;: Learned about SEO stuff and handled most of the meta tags as per standard.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Page Speed&lt;/strong&gt;: Google &lt;a href=&quot;https://developers.google.com/speed/pagespeed/insights/&quot;&gt;PageSpeed Insight&lt;/a&gt; tool is a fantastic tool. It helped me to improve the website structure. I also integrated &lt;a href=&quot;https://www.cloudflare.com/&quot;&gt;cloudflare CDN&lt;/a&gt; to improve latency. The score of &lt;a href=&quot;http://www.rohit.io&quot;&gt;Simplicity&lt;/a&gt; in PageSpeed Insight tool is now &lt;strong&gt;96/100&lt;/strong&gt; :-D&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Twitter card&lt;/strong&gt;: Added &lt;a href=&quot;https://dev.twitter.com/cards/overview&quot;&gt;twitter card&lt;/a&gt; support for previews in twitter for links.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;&lt;a href=&quot;http://ogp.me/&quot;&gt;The Open Graph protocol&lt;/a&gt;&lt;/strong&gt;: Added open graph related tags. This is used by Facebook and Linkedin for generating link previews.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Search&lt;/strong&gt;: Google CSE depends on Google indexing + the search results were displayed at google website. I wanted to have an in-house search feature. I found this awesome Jekyll plugin: &lt;a href=&quot;https://github.com/slashdotdash/jekyll-lunr-js-search&quot;&gt;jekyll lunr js search&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Google Analytics&lt;/strong&gt;: The bounce rate at home page was reduced to almost half. This was a bonus :-)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;&lt;strong&gt;Gyaan&lt;/strong&gt;: Static websites are great. Page load times are great. Hosting is free, reliable and scalable. 100% customization is possible. Basic dynamic features can be worked out using javascript. However, in the initial stages, it require&amp;rsquo;s a lot of development effort. Changing themes is also a pain.&lt;/p&gt;

&lt;p&gt;The source code of &lt;a href=&quot;http://www.rohit.io&quot;&gt;Simplicity&lt;/a&gt; is available &lt;a href=&quot;https://github.com/rohit01/rohit01.github.io&quot;&gt;here&lt;/a&gt;. &lt;strong&gt;And as always, Thanks for Reading :-)&lt;/strong&gt;&lt;/p&gt;

    <title>Not Just Another Independence Day</title>
    <link href="https://www.rohit.io/blog/not-just-another-independence-day.html"/>
    <updated>2014-08-18T03:35:00+05:30</updated>
    <id>https://www.rohit.io/blog/not-just-another-independence-day</id>
    <content type="html">&lt;p&gt;My alarm rang with a musical note, I turned it off and saw it&amp;rsquo;s 4:15 in the morning. Surprisingly, my friend was already awake and I wished him &lt;strong&gt;&lt;em&gt;Good Morning&lt;/em&gt;&lt;/strong&gt;, he replied &lt;strong&gt;&lt;em&gt;Jai Hind&lt;/em&gt;&lt;/strong&gt;. This was the start and it certainly set the mood for making it &lt;em&gt;Not Just Another Independence Day&lt;/em&gt;!&lt;/p&gt;

&lt;p&gt;It was 5:20 and we, the three idiots, were out in a patriotic mood to celebrate the national festival. We reached the MG Road metro station and found it already awake before 6 AM. My friend asked for a ticket to Chandni Chowk but instead, received a free travel coupon. The person at the ticket counter said that today &lt;strong&gt;&lt;em&gt;the ride to Chandni Chowk is Free&lt;/em&gt;&lt;/strong&gt;.&lt;/p&gt;

&lt;p&gt;It was 5:52 and we boarded the metro, but got no seats. It was easy to spot people with tricolor badge, traditional dress and young groups discussing national policies. I felt that my nation is now awake and ready to change. We reached Chandni Chowk at 6:45 and contributed to the queue, already too long. CRPF jawans were deployed at the station and were managing the crowd really well. Someone screamed, &lt;strong&gt;&lt;em&gt;Bharat Mata ki&lt;/em&gt;&lt;/strong&gt; and everyone replied &lt;strong&gt;&lt;em&gt;Jai&lt;/em&gt;&lt;/strong&gt;. This slogan continued throughout our way to Red Fort. I was like, &lt;em&gt;wow&lt;/em&gt;!&lt;/p&gt;

&lt;p&gt;As we moved out of the Metro station, we saw the security arrangements. On our way to Red Fort, I saw Delhi police, CRPF jawans, SWAT team, NSG Black Cats, Snipers on roof tops and many more. They seemed to outnumber the number of civilians attending the event. At around 7:20, we were at the gallery and as expected, the seats were already full. I took a look around and saw that the Red Fort looked really beautiful, our national flag was flying all over the place, four giant screens displayed the venue live, Doordarshan had built high bamboo towers to cover the event live. Then, I heard someone saying, &amp;ldquo;Aaa gaya&amp;rdquo; (he came), I looked at the screen, our PM was here. People started clapping.&lt;/p&gt;

&lt;p&gt;Our PM was here with a style. The Jodhpuri turban was not less than a fashion statement. He gradually reached the stage. An army official shouted something really loud. I heard it clear at a distance of about 500m. Moments later, the PM pulled the rope and our National Flag was flying. But wait, something exploded, something really loud on my right. Is it a bomb?&amp;hellip; Everyone trying to see. Phew, it is part of the 21 Gun Salute (Ekkess Topon Ki Salami). I was wondering, if this is the situation here, what would be like to be on a battlefield.&lt;/p&gt;

&lt;p&gt;After an awesome flag hosting moment, the PM reached the Mic. No bullet proof glass on his front, no scripts to read, the gallery is waiting silently, more than a million eyes glued to the television, birds flying above the fort, the tail of his turban flying like a flag and he starts his speech. An hour long speech, and what a speech. There was total silence among the audience and when someone spoke, it was to clarify his last words - &lt;strong&gt;&lt;em&gt;Kya bola?&lt;/em&gt;&lt;/strong&gt; (&lt;strong&gt;&lt;em&gt;What did he say?&lt;/em&gt;&lt;/strong&gt;). The audience also acknowledged most of his statements with a round of applause. The speech ended with loud, energetic slogans of &lt;strong&gt;&lt;em&gt;Bharat Mata ki Jai&lt;/em&gt;&lt;/strong&gt; and &lt;strong&gt;&lt;em&gt;Jai Hind&lt;/em&gt;&lt;/strong&gt;. Post this, the national anthem was played. This concluded the event, but we decided to leave a little late and saw the PM among cute children.&lt;/p&gt;

&lt;p&gt;After some time, we left the venue at around 9 AM and decided to try out the paratha from the world famous &lt;strong&gt;&lt;em&gt;parathe wali gali&lt;/em&gt;&lt;/strong&gt;. As we headed towards the same, we wondered if it was open. Most of the shops were closed and some people said the paratha shop usually opens at 10 AM and today, it might be closed. Determined to taste the lovely parathas, we moved against all odds. And finally, we were at the historic &lt;strong&gt;&lt;em&gt;parathe wali gali&lt;/em&gt;&lt;/strong&gt;. The paratha shops were open and the fragrance in the air was making us hungry. But wait, we need to wait&amp;hellip; The shop is already full and there is a queue outside the shop. The board at one of the shops, reads - Oldest and famous, serving parathas through 5 generations. There were pictures of many famous personalities like &lt;strong&gt;&lt;em&gt;Lal bahadur sastri&lt;/em&gt;&lt;/strong&gt;, &lt;strong&gt;&lt;em&gt;Indira Gandhi&lt;/em&gt;&lt;/strong&gt;, &lt;strong&gt;&lt;em&gt;Ranbir Kapoor&lt;/em&gt;&lt;/strong&gt;, &lt;strong&gt;&lt;em&gt;Akshay Kumar&lt;/em&gt;&lt;/strong&gt;, &lt;strong&gt;&lt;em&gt;Sheila Dikshit&lt;/em&gt;&lt;/strong&gt; and many more. In the pictures, parathas were being served to all, but&amp;hellip; we need to wait!!&lt;/p&gt;

&lt;p&gt;Finally, &lt;strong&gt;&lt;em&gt;hamara number aa gaya&lt;/em&gt;&lt;/strong&gt; (it was our turn). The menu looked like a sabzi market with paratha after every vegetable name. You name it and it&amp;rsquo;s there. Aloo, tomato, gobi, muli, etc + some strange ones too like rabri paratha. The menu also revealed, &lt;strong&gt;&lt;em&gt;its India at its best with the most affordable rates&lt;/em&gt;&lt;/strong&gt;. The table had some free munchies and parathas were served well on time. We ate like pigs and then ordered lassi from another shop. The lassi was served on a kulhad (glass made of clay) with a slice of Malai (cream of milk) on top. It was the best Lassi I ever had in my life.&lt;/p&gt;

&lt;p&gt;Post this we headed towards the metro station. It was again, over crowded, but CRPF jawans managed it really well. In the metro, a person caught our attention as he was carrying a box of Bengali sweets. He was formally dressed in grey pants and light colored shirt. After some time, he joined our conversation about PM&amp;rsquo;s speech. I asked him if he went to the Red Fort and he replied, &amp;ldquo;&lt;strong&gt;No. I went to the office for the flag hosting ceremony. This time, everybody was present. Instructions were given that if anyone is absent, his/her accountability will be checked&lt;/strong&gt;&amp;rdquo;. He cherished the PM&amp;rsquo;s initiative on punctuality but revealed that some government officials are unhappy about it. Once we reached home, we saw the news channels analyzing independence day speech, but we crashed on the bed sooner than expected!&lt;/p&gt;

&lt;p&gt;How did you celebrate the National Festival? Waiting to hear your answer and feedback in comments. &lt;strong&gt;And as always, Thanks for reading :-)&lt;/strong&gt;&lt;/p&gt;

    <title>Contributing to Ansible is Super Easy</title>
    <link href="https://www.rohit.io/blog/contributing-to-ansible-is-super-easy.html"/>
    <updated>2014-08-05T13:23:00+05:30</updated>
    <id>https://www.rohit.io/blog/contributing-to-ansible-is-super-easy</id>
    <content type="html">&lt;p&gt;Just three days back, I thought about writing a SMS notification module and bingo, I was able to send a &lt;a href=&quot;https://github.com/ansible/ansible/pull/8408&quot;&gt;pull request&lt;/a&gt;, same day. I submitted a module named &amp;lsquo;plivo&amp;rsquo; which allows sending SMS notification using &lt;a href=&quot;https://www.plivo.com&quot;&gt;Plivo&lt;/a&gt; services. The playbook examples are hosted here: &lt;a href=&quot;https://github.com/rohit01/ansible-plivo-example&quot;&gt;https://github.com/rohit01/ansible-plivo-example&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Writing an &lt;a href=&quot;http://ansible.com&quot;&gt;Ansible&lt;/a&gt; module, is pretty much a straight forward approach. Though ansible modules can be written in any language, I will stick to Python in this post. In Python, a module is generally a single file with 3 different parts:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;strong&gt;Documentation&lt;/strong&gt;: This usually takes up the most number of lines&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Logic&lt;/strong&gt;: The real programming logic to perform the task&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Ansible framework&lt;/strong&gt;: Ansible provides some really useful classes and functions to help you in this process&lt;/li&gt;
&lt;/ol&gt;


&lt;h2&gt;Documentation&lt;/h2&gt;

&lt;p&gt;Ansible is designed to read two global variables and generate documentation. These are:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Documentation&lt;/strong&gt;: A multiline string literal and a valid YAML document. It contains the detailed description of module we see using the command &lt;code&gt;ansible-doc &amp;lt;module_name&amp;gt;&lt;/code&gt; or at &lt;a href=&quot;http://docs.ansible.com&quot;&gt;docs.ansible.com&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Examples&lt;/strong&gt;: A multiline string literal and a valid YAML document. It demonstrates the sample usage of module.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;h2&gt;Logic&lt;/h2&gt;

&lt;p&gt;Logic is the programatic way to perform the task. It uses various resources provided by Ansible. These resources may include the arguments passed to module, ssh connection to host, cloud resources such as AWS, GAE, and many more. Ansible will connect to the host only if logic requires the same. For example, a notification module does not connect to the host for sending SMS, email, etc.&lt;/p&gt;

&lt;h2&gt;Ansible Framework&lt;/h2&gt;

&lt;p&gt;Ansible modules usually import a bunch of utilities to perform its task. The basic utilities are generally imported by all modules using the following import statement:&lt;/p&gt;

&lt;pre&gt;&lt;code class=&quot;python&quot;&gt;    from ansible.module_utils.basic import *
&lt;/code&gt;&lt;/pre&gt;

&lt;hr /&gt;

&lt;h2&gt;Lets write a simple module&lt;/h2&gt;

&lt;p&gt;&lt;strong&gt;Module to return a configurable string and control success status:&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;noscript&gt;&lt;pre&gt;#!/usr/bin/python&lt;/p&gt;

&lt;h1&gt;-&lt;em&gt;- coding: utf-8 -&lt;/em&gt;-&lt;/h1&gt;

&lt;p&gt;#&lt;/p&gt;

&lt;h1&gt;Author: Rohit Gupta - @rohit01 &amp;lt;rohit.kgec@gmail.com&amp;gt;&lt;/h1&gt;

&lt;p&gt;#&lt;/p&gt;

&lt;h1&gt;Sample ansible module to demonstrate code structure.&lt;/h1&gt;

&lt;p&gt;#&lt;/p&gt;

&lt;h1&gt;&amp;mdash;- Documentation Start &amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;-&lt;/h1&gt;

&lt;h2&gt;DOCUMENTATION = &amp;#39;&amp;#39;&amp;#39;&lt;/h2&gt;

&lt;p&gt;version_added: &amp;quot;1.7&amp;quot;
module: echo
short_description: echo
description:
  - This module returns/displays a configured string
options:
  name:
    description:
      text message to print
  success:
    description:
      If false, the module will exit with failure.
    required: false
    default: yes
    choices: [ &amp;quot;yes&amp;quot;, &amp;quot;no&amp;quot; ]
notes:
  - This module does not connect to host. It is a dummy module
    required: true
requirements: []
author: Rohit Gupta - @rohit01
&amp;#39;&amp;#39;&amp;#39;&lt;/p&gt;

&lt;p&gt;EXAMPLES = &amp;#39;&amp;#39;&amp;#39;
- name: &amp;quot;echo&amp;quot;
  echo: name=&amp;quot;I executed successfully&amp;quot; success=yes
&amp;#39;&amp;#39;&amp;#39;&lt;/p&gt;

&lt;h1&gt;&amp;mdash;- Logic Start &amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&lt;/h1&gt;

&lt;p&gt;def main():
    # Note: &amp;#39;AnsibleModule&amp;#39; is an Ansible utility imported below
    module = AnsibleModule(
        argument_spec=dict(
            name=dict(required=True),
            success = dict(default=True, type=&amp;#39;bool&amp;#39;),
        ),
        supports_check_mode=True
    )
    success = module.params[&amp;#39;success&amp;#39;]
    text = module.params[&amp;#39;name&amp;#39;]
    if success:
      module.exit_json(text=text)
    else:
      module.fail_json(msg=text)&lt;/p&gt;

&lt;h1&gt;&amp;mdash;- Import Ansible Utilities (Ansible Framework) &amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&amp;mdash;&lt;/h1&gt;

&lt;p&gt;from ansible.module_utils.basic import *
main()
&lt;/pre&gt;&lt;/noscript&gt;&lt;script src=&quot;https://gist.github.com/rohit01/7ce30e3d3f12a4901fe2.js&quot;&gt; &lt;/script&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;And the examples to use this module is also simple:&lt;/strong&gt;&lt;/p&gt;

&lt;pre&gt;&lt;code class=&quot;YAML&quot;&gt;    - echo: name=&quot;Hello World!&quot;
    - echo: name=&quot;Success is Yes&quot; success=yes
    - echo: name=&quot;Success is No&quot; success=no
&lt;/code&gt;&lt;/pre&gt;

&lt;h2&gt;Write your own module&lt;/h2&gt;

&lt;p&gt;Now that you know some basics, why not write something on your own. For more details on developing modules, I highly recommend the following:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Check some real module related to the one you are writing. Ansible modules are hosted &lt;a href=&quot;https://github.com/ansible/ansible/tree/devel/library&quot;&gt;here&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Visit the &lt;a href=&quot;http://docs.ansible.com/developing_modules.html&quot;&gt;Ansible documentation on developing modules&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Find Ansible utilities you may like to re-use. You can find them &lt;a href=&quot;https://github.com/ansible/ansible/tree/devel/lib/ansible/module_utils&quot;&gt;here&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Share what you want to write and feedback in comments. &lt;strong&gt;And as always, Thanks for reading :-)&lt;/strong&gt;&lt;/p&gt;
