kangol

Container Deploy and Manage System at Amazon Elastic Container Service(ECS). You can use YAML files to manage docker container(task-definition at ECS). And when kangol catches the errors at ECS deploy, it can revert before revision automatically.

Installation

go get -u github.com/recruit-mp/kangol

Usage

• setting up environment variable for AWS credential

export AWS_ACCESS_KEY_ID=<YOUR AWS_ACCESS_KEY_ID>
export AWS_SECRET_ACCESS_KEY=<YOUR AWS_SECRET_ACCESS_KEY>
export AWS_DEFAULT_REGION=<ECS AWS_DEFAULT_REGION>

and then, if you colud through the GOPATH at your environment. You can use like this.

kangol --conf ./nginx.yml

• run only one ECS task

kangol --conf ./api.yaml --tag api:12345abc --command "bundle exec rake db:migrate"

Options

GLOBAL OPTIONS:
   --conf               ECS service family at task definition
   --tag                --tag has a container tag
   --debug              --debug has a debug mode
   --loading            --loading has a loading while deploying
   --help, -h           show help
   --version, -v        print the version

tag

if you want to change docker container tag

kangol --conf ./api.yml --tag api:<CONTAINER_TAG_NUM>

(ex)

kangol --conf ./api.yml --tag api:b34cda71

debug mode

You want to stop all container at a service before you want to deployed because ECS show 'resource not found' because of few your resources in your cluster.

I'll recommend to apply your development environment at ECS.

(ex)

kangol --conf ./nginx.yml --tag nginx:latest --debug

loading mode

if you think kangol loading disturbed your deployment environment, you should add loading option. When you off lading option, kangol will not show loading while deploying.

(ex) loading on

kangol --conf ./nginx.yml --tag nginx:latest --debug --loading

(ex) loading off

kangol --conf ./nginx.yml --tag nginx:latest --debug
