SendCommand 搭配 a AWS SDK 或 CLI 使用

下列程式碼範例示範如何使用 SendCommand

動作範例是大型程式的程式碼摘錄,必須在內容中執行。您可以在下列程式碼範例的內容中看到此動作:

CLI
AWS CLI

範例 1:在一或多個遠端執行個體上執行命令

下列send-command範例會在目標執行個體上執行 echo命令。

aws ssm send-command \ --document-name "AWS-RunShellScript" \ --parameters 'commands=["echo HelloWorld"]' \ --targets "Key=instanceids,Values=i-1234567890abcdef0" \ --comment "echo HelloWorld"

輸出:

{ "Command": { "CommandId": "92853adf-ba41-4cd6-9a88-142d1EXAMPLE", "DocumentName": "AWS-RunShellScript", "DocumentVersion": "", "Comment": "echo HelloWorld", "ExpiresAfter": 1550181014.717, "Parameters": { "commands": [ "echo HelloWorld" ] }, "InstanceIds": [ "i-0f00f008a2dcbefe2" ], "Targets": [], "RequestedDateTime": 1550173814.717, "Status": "Pending", "StatusDetails": "Pending", "OutputS3BucketName": "", "OutputS3KeyPrefix": "", "MaxConcurrency": "50", "MaxErrors": "0", "TargetCount": 1, "CompletedCount": 0, "ErrorCount": 0, "DeliveryTimedOutCount": 0, "ServiceRole": "", "NotificationConfig": { "NotificationArn": "", "NotificationEvents": [], "NotificationType": "" }, "CloudWatchOutputConfig": { "CloudWatchLogGroupName": "", "CloudWatchOutputEnabled": false } } }

如需範例輸出,請參閱範例 1。

如需詳細資訊,請參閱 Systems Manager 使用者指南中的使用 Systems Manager 執行命令執行命令AWS

範例 6:在具有不同標籤的多個執行個體上執行命令

下列send-command範例會在具有兩個不同標籤索引鍵和值的執行個體上執行 命令。

aws ssm send-command \ --document-name "AWS-RunPowerShellScript" \ --parameters commands=["echo helloWorld"] \ --targets Key=tag:Env,Values=Dev Key=tag:Role,Values=WebServers

如需範例輸出,請參閱範例 1。

範例 7:以具有相同標籤索引鍵的多個執行個體為目標

下列send-command範例會在具有相同標籤索引鍵但具有不同值的執行個體上執行命令。

aws ssm send-command \ --document-name "AWS-RunPowerShellScript" \ --parameters commands=["echo helloWorld"] \ --targets Key=tag:Env,Values=Dev,Test

如需範例輸出,請參閱範例 1。

範例 8:執行使用共用文件的命令

下列send-command範例會在目標執行個體上執行共用文件。

aws ssm send-command \ --document-name "arn:aws:ssm:us-east-1:123456789012:document/ExampleDocument" \ --targets "Key=instanceids,Values=i-1234567890abcdef0"
