Your application is now running on a container in Amazon ECS.
'; C:\\ServiceMonitor.exe w3svc"], "entryPoint": [ "powershell", "-Command" ], "essential": true, "cpu": 2048, "memory": 4096, "image": "mcr.microsoft.com/windows/servercore/iis:windowsservercore-ltsc2019", "name": "sample_windows_app", "portMappings": [ { "hostPort": 80, "containerPort": 80, "protocol": "tcp" } ] } ], "memory": "4096", "cpu": "2048", "networkMode": "awsvpc", "family": "windows-simple-iis-2019-core", "executionRoleArn": "arn:aws:iam::012345678910:role/ecsTaskExecutionRole", "runtimePlatform": {"operatingSystemFamily": "WINDOWS_SERVER_2019_CORE"}, "requiresCompatibilities": ["FARGATE"] } ``` 上述範例 JSON 可以透過 AWS CLI 兩種方式傳遞至 ：您可以將任務定義 JSON 儲存為 檔案，並使用 `--cli-input-json file://{{path_to_file.json}}`選項將其傳遞。 將 JSON 檔案用於容器定義中： ``` aws ecs register-task-definition --cli-input-json {{file://$HOME/tasks/fargate-task.json}} ``` **register-task-definition** 命令會在完成註冊後傳回任務定義的描述。 ## 步驟 3：列出任務定義 您可以使用 **list-task-definitions** 命令隨時列出您帳戶的任務定義。這個命令的輸出會顯示 `family` 和 `revision` 值，可在呼叫 **run-task** 或 **start-task** 時一起使用。 ``` aws ecs list-task-definitions ``` 輸出： ``` { "taskDefinitionArns": [ "arn:aws:ecs:{{region}}:{{aws_account_id}}:task-definition/sample-fargate-windows:1" ] } ``` ## 步驟 4：建立服務 為您的帳戶註冊任務之後，您就可以在您的叢集中建立已註冊任務的服務。在此範例中，您將透過在叢集中執行之 `sample-fargate:1` 任務定義的一個執行個體建立服務。該任務需要網際網路的路由，因此您可透過兩種方法達成。一種方法是，使用透過 NAT 閘道所設定的私有子網路，而該閘道在公有子網路中具有彈性 IP 地址。另一種方法是，使用公有子網路並將公有 IP 地址指派至任務。以下提供這兩種範例。 使用私有子網路的範例。 ``` aws ecs create-service --cluster {{fargate-cluster}} --service-name {{fargate-service}} --task-definition {{sample-fargate-windows:1}} --desired-count {{1}} --launch-type "FARGATE" --network-configuration "awsvpcConfiguration={subnets=[{{subnet-abcd1234}}],securityGroups=[{{sg-abcd1234}}]}" ``` 使用公有子網路的範例。 ``` aws ecs create-service --cluster {{fargate-cluster}} --service-name {{fargate-service}} --task-definition {{sample-fargate-windows:1}} --desired-count {{1}} --launch-type "FARGATE" --network-configuration "awsvpcConfiguration={subnets=[{{subnet-abcd1234}}],securityGroups=[{{sg-abcd1234}}],assignPublicIp={{ENABLED}}}" ``` **create-service** 命令會在完成註冊後傳回任務定義的描述。 ## 步驟 5：列出服務 列出您叢集的服務。您應該會看到您在先前一節所建立的服務。您可以記下這個命令傳回的服務名稱或完整的 ARN，稍後將用以描述服務。 ``` aws ecs list-services --cluster {{fargate-cluster}} ``` 輸出： ``` { "serviceArns": [ "arn:aws:ecs:{{region}}:{{aws_account_id}}:service/fargate-service" ] } ``` ## 步驟 6：描述執行中的服務 使用之前擷取的服務名稱來描述服務，以取得任務的詳細資訊。 ``` aws ecs describe-services --cluster {{fargate-cluster}} --services {{fargate-service}} ``` 如果成功，這會傳回服務失敗和服務的描述。例如，在服務區段中，您將可以找到部署的相關資訊，例如執行中或擱置中的任務狀態。您也可以找到任務定義、網路組態和時間戳記事件的相關資訊。在失敗區段中，您將可以找到與呼叫相關聯的失敗 (如果有的話) 的相關資訊。如需故障診斷，請參閱[服務事件訊息](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-event-messages.html)。如需服務描述的詳細資訊，請參閱[描述服務](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_DescribeServices)。 ``` { "services": [ { "status": "ACTIVE", "taskDefinition": "arn:aws:ecs:{{region}}:{{aws_account_id}}:task-definition/sample-fargate-windows:1", "pendingCount": 2, "launchType": "FARGATE", "loadBalancers": [], "roleArn": "arn:aws:iam::{{aws_account_id}}:role/aws-service-role/ecs.amazonaws.com/AWSServiceRoleForECS", "placementConstraints": [], "createdAt": 1510811361.128, "desiredCount": 2, "networkConfiguration": { "awsvpcConfiguration": { "subnets": [ "{{subnet-abcd1234}}" ], "securityGroups": [ "{{sg-abcd1234}}" ], "assignPublicIp": "DISABLED" } }, "platformVersion": "LATEST", "serviceName": "fargate-service", "clusterArn": "arn:aws:ecs:{{region}}:{{aws_account_id}}:cluster/fargate-cluster", "serviceArn": "arn:aws:ecs:{{region}}:{{aws_account_id}}:service/fargate-service", "deploymentConfiguration": { "maximumPercent": 200, "minimumHealthyPercent": 100 }, "deployments": [ { "status": "PRIMARY", "networkConfiguration": { "awsvpcConfiguration": { "subnets": [ "{{subnet-abcd1234}}" ], "securityGroups": [ "{{sg-abcd1234}}" ], "assignPublicIp": "DISABLED" } }, "pendingCount": 2, "launchType": "FARGATE", "createdAt": 1510811361.128, "desiredCount": 2, "taskDefinition": "arn:aws:ecs:{{region}}:{{aws_account_id}}:task-definition/sample-fargate-windows:1", "updatedAt": 1510811361.128, "platformVersion": "0.0.1", "id": "ecs-svc/9223370526043414679", "runningCount": 0 } ], "events": [ { "message": "(service fargate-service) has started 2 tasks: (task 53c0de40-ea3b-489f-a352-623bf1235f08) (task d0aec985-901b-488f-9fb4-61b991b332a3).", "id": "92b8443e-67fb-4886-880c-07e73383ea83", "createdAt": 1510811841.408 }, { "message": "(service fargate-service) has started 2 tasks: (task b4911bee-7203-4113-99d4-e89ba457c626) (task cc5853e3-6e2d-4678-8312-74f8a7d76474).", "id": "d85c6ec6-a693-43b3-904a-a997e1fc844d", "createdAt": 1510811601.938 }, { "message": "(service fargate-service) has started 2 tasks: (task cba86182-52bf-42d7-9df8-b744699e6cfc) (task f4c1ad74-a5c6-4620-90cf-2aff118df5fc).", "id": "095703e1-0ca3-4379-a7c8-c0f1b8b95ace", "createdAt": 1510811364.691 } ], "runningCount": 0, "placementStrategy": [] } ], "failures": [] } ``` ## 步驟 7：清除 完成此教學課程時，建議您清除相關聯的資源，以免未使用的資源產生費用。 刪除服務。 ``` aws ecs delete-service --cluster {{fargate-cluster}} --service {{fargate-service}} --force ``` 刪除叢集。 ``` aws ecs delete-cluster --cluster {{fargate-cluster}} ```
