CreateCluster 搭配 AWS SDK 或 CLI 使用

範例 1：建立新叢集

下列create-cluster範例會建立叢集。

aws ecs create-cluster \
    --cluster-name MyCluster

輸出：

{
    "cluster": {
        "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
        "clusterName": "MyCluster",
        "status": "ACTIVE",
        "registeredContainerInstancesCount": 0,
        "pendingTasksCount": 0,
        "runningTasksCount": 0,
        "activeServicesCount": 0,
        "statistics": [],
        "tags": []
    }
}

如需詳細資訊，請參閱《Amazon ECS 開發人員指南》中的建立叢集。

範例 2：使用容量提供者建立新叢集

下列create-cluster範例會建立叢集，並將兩個現有容量提供者與其建立關聯。create-capacity-provider 命令用於建立容量提供者。指定預設容量提供者策略是選用的，但建議使用。在此範例中，我們會建立名為 的叢集，MyCluster並將 MyCapacityProvider1 和MyCapacityProvider2容量提供者與其建立關聯。系統會指定預設容量提供者策略，將任務平均分散到兩個容量提供者。

aws ecs create-cluster --cluster-name MyCluster --capacity-providers MyCapacityProvider1 MyCapacityProvider2 --default-capacity-provider-strategy capacityProvider=MyCapacityProvider1，weight=1 capacityProvider=MyCapacityProvider2，weight=1

輸出：

{
    "cluster": {
        "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
        "clusterName": "MyCluster",
        "status": "PROVISIONING",
        "registeredContainerInstancesCount": 0,
        "pendingTasksCount": 0,

            }
        ],
        "capacityProviders": [
            "MyCapacityProvider1",
            "MyCapacityProvider2"
        ],
        "defaultCapacityProviderStrategy": [
            {

                "weight": 1,
                "base": 0
            },
            {
                "capacityProvider": "MyCapacityProvider2",
                "weight": 1,
                "base": 0
            }
        ],
        "attachments": [
           {
                "id": "0fb0c8f4-6edd-4de1-9b09-17e470ee1918",

                        "value": "MyCapacityProvider1"
                    },
                    {
                        "name": "scalingPlanName",
                        "value": "ECSManagedAutoScalingPlan-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"
                    }
                ]
            },

                    },

                    }
                ]

        ],
        "attachmentsStatus": "UPDATE_IN_PROGRESS"
    }
}

範例 3：建立具有多個標籤的新叢集

下列create-cluster範例會建立具有多個標籤的叢集。如需使用速記語法新增標籤的詳細資訊，請參閱《AWS CLI 使用者指南》中的使用速記語法搭配 AWS 命令列界面。

aws ecs create-cluster \
    --cluster-name MyCluster \
    --tags key=key1,value=value1 key=key2,value=value2 key=key3,value=value3

輸出：

{
    "cluster": {
        "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
        "clusterName": "MyCluster",
        "status": "ACTIVE",
        "registeredContainerInstancesCount": 0,
        "pendingTasksCount": 0,
        "runningTasksCount": 0,
        "activeServicesCount": 0,
        "statistics": [],
        "tags": [
            {
                "key": "key1",
                "value": "value1"
            },
            {
                "key": "key2",
                "value": "value2"
            },
            {
                "key": "key3",
                "value": "value3"
            }
        ]
    }
}
