Website on Ec2 instances

This project contains two stacks, a network stack, and a server stack. The purpose of this project is to show understanding of the AWS CDK & resources that can be launched using it. Listed below are the stacks and the resources inside of them.

Network Stack (cdk_assignment_stack.py)

• One public and one private subnet in one AZ
• One public and one private subnet in a different AZ

Server Stack (cdk_server_stack.py)

• One EC2 webserver launched in each of the public subnets
• An RDS instance with MYSQL engine with all private subnets as its subnet group
• A security group for the web server that opens port 80 from anywhere
• A security group for the RDS instance that opens port 3306 to the web server security group

CDK Instructions

To manually create a virtualenv on MacOS and Linux:

$ python3 -m venv .venv

After the init process completes and the virtualenv is created, you can use the following step to activate your virtualenv.

$ source .venv/bin/activate

If you are a Windows platform, you would activate the virtualenv like this:

% .venv\Scripts\activate.bat

Once the virtualenv is activated, you can install the required dependencies.

$ pip install -r requirements.txt

At this point you can now synthesize the CloudFormation template for this code.

$ cdk synth

To add additional dependencies, for example other CDK libraries, just add them to your setup.py file and rerun the pip install -r requirements.txt command.

Useful commands

• cdk ls list all stacks in the app
• cdk synth emits the synthesized CloudFormation template
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk docs open CDK documentation

Enjoy!
