1. ecs-cliのインストール

https://docs.aws.amazon.com/ja_jp/AmazonECS/latest/developerguide/ECS_CLI_installation.html

2. プロファイル等の事前設定 

$ ecs-cli configure profile --profile-name fargate-test --access-key $AWS_ACCESS_KEY --secret-key $AWS_SECRET_ACCESS_KEY
$ ecs-cli configure --cluster fargate-test --default-launch-type FARGATE --region us-east-1 --config-name fargate-test

3. クラスタの立ち上げ 

$ ecs-cli up
INFO[0000] Created cluster                               cluster=fargate-test region=us-east-1
INFO[0000] Waiting for your cluster resources to be created... 
INFO[0001] Cloudformation stack status                   stackStatus=CREATE_IN_PROGRESS
INFO[0061] Cloudformation stack status                   stackStatus=CREATE_IN_PROGRESS
VPC created: vpc-22fef559
Subnet created: subnet-82ad7be5
Subnet created: subnet-8864b1a6
Cluster creation succeeded.

4. 生成されたVPCに紐づくセキュリティグループを作成

後ほどecs-params.ymlに書き込みます

$ aws ec2 create-security-group --group-name "fargate-sg" --description "My security group" --vpc-id "vpc-22fef559"
{
    "GroupId": "sg-0a333542"
}

$ aws ec2 authorize-security-group-ingress --group-id "sg-0a333542" --protocol tcp --port 80 --cidr 0.0.0.0/0

5. ECSタスク実行用のIAMロールを作成

6. docker-compose.yml と ecs-params.yml を作成 

$ vim docker-compose.yml

$ vim ecs-params.yml

docker-compose.yml 

version: '2'
services:
  nginx:
    image: nginx
    ports:
      - "80:80"
    logging:
      driver: awslogs
      options: 
        awslogs-group: tutorial
        awslogs-region: us-east-1
        awslogs-stream-prefix: nginx

ecs-params.yml 

version: 1
task_definition:
  task_execution_role: ecsExecutionRole <- あらかじめ作成が必要(cloudwatch logs の書き込み権限がいる)
  ecs_network_mode: awsvpc
  task_size:
    mem_limit: 512
    cpu_limit: 256
run_params:
  network_configuration:
    awsvpc_configuration:
      subnets:
        - "subnet-82ad7be5"
        - "subnet-8864b1a6"
      security_groups:
        - "sg-0a333542"
      assign_public_ip: ENABLED

7. タスクを起動・停止する 

$ ecs-cli compose --project-name tutorial service up (--create-log-groups)初回のupのみ

$ ecs-cli compose --project-name tutorial service ps

$ ecs-cli compose --project-name tutorial service down
