  1. クラスタの確認
    =================

5.1. クラスタの確認

コマンド
aws ecs describe-clusters \
  --clusters ${ECS_CLUSTER_NAME}
結果(例)
       {
         "clusters": [
           {
             "status": "ACTIVE",
             "clusterName": "handson-cluster",
             "registeredContainerInstancesCount": 1,
             "pendingTasksCount": 0,
             "runningTasksCount": 0,
             "activeServicesCount": 0,
             "clusterArn": "arn:aws:ecs:ap-northeast-1:XXXXXXXXXXXX:cluster/handson-cluster"
           }
         ],
         "failures": []
      }

5.2. コンテナインスタンスの確認

コマンド
ECS_INSTANCES=$( \
        aws ecs list-container-instances \
          --cluster ${ECS_CLUSTER_NAME} \
          --query 'containerInstanceArns[]' \
          --output text | \
        sed 's|^arn:aws:ecs:.*:container-instance/||' \
) \
        && echo ${ECS_INSTANCES}
結果(例)
      xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
コマンド
aws ecs describe-container-instances \
  --cluster ${ECS_CLUSTER_NAME} \
  --container-instances "${ECS_INSTANCES}" 
結果(例)
