[JAWS-UG CLI] ECS #2 タスク定義の登録、タスク実行、削除

Last updated at Posted at 2015-07-06

AWS CLIを利用して、ECS上にタスク定義を登録、タスク実行、タスク定義の削除をしてみます。

参考: http://docs.aws.amazon.com/AmazonECS/latest/developerguide/ECS_AWSCLI.html#AWSCLI_register_task_definition

前提条件

ECSへの権限

  • ECSに対してフル権限があること。

AWS CLIのバージョン

  • 以下のバージョンで動作確認済

    • AWS CLI 1.7.36
コマンド
aws --version
結果(例)
      aws-cli/1.7.28 Python/2.7.5 Darwin/13.4.0
  1. 準備
    =======

0.1. リージョンの決定

変数の設定
export AWS_DEFAULT_REGION='ap-northeast-1'

0.2. 変数の確認

変数の確認
aws configure list
結果(例)
            Name                    Value             Type    Location
            ----                    -----             ----    --------
         profile   ec2ecs_full-prjZ-mbp13              env    AWS_DEFAULT_PROFILE
      access_key     ****************LOAQ shared-credentials-file
      secret_key     ****************I1O1 shared-credentials-file
          region           ap-northeast-1              env    AWS_DEFAULT_REGION
  1. 事前作業
    ===========

1.1. タスク定義名の決定

変数の設定
ECS_TASK_DEFINITION_NAME='sleep360'

同じ名前のタスク定義名が存在しないことを確認します。

コマンド
aws ecs describe-task-definition \
        --task-definition ${ECS_TASK_DEFINITION_NAME}
結果(例)
      A client error (ClientException) occurred when calling the DescribeTaskDefinition operation: Unable to describe task definition.

1.2. タスク定義ファイルの作成

変数の設定
FILE_ECS_TASK_DEFINITION='sleep360.json'
コマンド
cat << EOF > ${FILE_ECS_TASK_DEFINITION}
{
        "containerDefinitions": [
          {
            "name": "sleep",
            "image": "busybox",
            "cpu": 10,
            "command": [
              "sleep",
              "360"
            ],
            "memory": 10,
            "essential": true
          }
        ],
        "family": "sleep360"
}
EOF

JSONファイルを作成したら、フォーマットが壊れてないか必ず確認します。

コマンド
jsonlint -q ${FILE_ECS_TASK_DEFINITION}
結果
      (戻り値なし)
