ECS manager

AWS ECSのラッパーコマンドです.

環境変数などを組み合わせたECSのタスクをシンプルなコマンドでデプロイできます。

使い方

前提条件として AWS CLI が使えるよう環境変数がセットされている必要があります。

pip3 install ecs_manager

# Example
ecs_manager deploy-service test-service -c default -t "[{\"name\":\"sleep\",\"image\":\"busybox\",\"cpu\":10,\"command\":[\"sleep\",\"360\"],\"memory\":10,\"essential\":true}]" -s '{"desiredCount": 1}'

# => ECS 上にサービスが生成されます

NAME 作ろうとしているECSのサービス名です。

cluster

          "containerPort": 80,
          "hostPort": 80
        }
      ],
      "memory": 500,
      "cpu": 10
    },
    {
      "environment": [
        {

          "value": "password"
        }

You can add --task_definition_only option for registering task definition without updating ecs service

ecs_manager deploy-service test-service --task_definition_only -c default -t "[{\"name\":\"sleep\",\"image\":\"busybox\",\"cpu\":10,\"command\":[\"sleep\",\"360\"],\"memory\":10,\"essential\":true}]" -s '{"desiredCount": 1}'
