This repo is used to learn using the Amazon EC2 Container Service

Setup AWS

1. Install AWS Command line interface

$ pip install --upgrade --user awscli

2. Configure it with your credentials

$ aws configure

3. Install AWS ECS Command line interface

$ sudo curl -o /usr/local/bin/ecs-cli https://s3.amazonaws.com/amazon-ecs-cli/ecs-cli-darwin-amd64-latest

4. Apply execute permissions

$ sudo chmod +x /usr/local/bin/ecs-cli

How to

1. Create your cluster. Use a EC2 Keypair pem file

ecs-cli up --keypair id_rsa --capability-iam --size 2 --instance-type t2.medium

2. Create a compose file docker-compose.yml

version: '2'
services:
  wordpress:
    image: wordpress
    cpu_shares: 100
    mem_limit: 524288000
    ports:
      - "80:80"
    links:
      - mysql
  mysql:
    image: mysql
    cpu_shares: 100
    mem_limit: 524288000
    environment:
      MYSQL_ROOT_PASSWORD: password

3. Deploy compose file to cluster

$ ecs-cli compose --file hello-world.yml up

4. View the running containers on a cluster

$ ecs-cli ps

5. Scale the tasks on the cluster

ecs-cli compose --file hello-world.yml scale 2

6. Create an ECS Service from compose file

Stop all containers

$ ecs-cli compose --file hello-world.yml down

Create service

$ ecs-cli compose --file hello-world.yml service up

7. Clean up

Delete the service

$ ecs-cli compose --file hello-world.yml service rm

Take down cluster

$ ecs-cli down --force

Amazon EC2 Container Registry

1. Authenticate Docker to an Amazon ECR registry with get-login

$ aws ecr get-login

2. Copy and paste the docker login command into a terminal to authenticate your Docker CLI to the registry.

3. Create a repository

$ aws ecr create-repository --repository-name myrepo

4. Push an image to Amazon ECR

$ docker images

Tag the image to push to your repository. Update it with your AWS account id and aws ECR domain.

$ docker tag myimage AWS_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/myimage

Push the image.

$ docker push AWS_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/myimage

5. Pull an image from Amazon ECR

$ docker pull AWS_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/myimage

6. Delete an image

$ aws ecr batch-delete-image --repository-name myrepo --image-ids imageTag=myimage

7. Delete repository

$ aws ecr delete-repository --repository-name myrepo --force
