使用分支过滤器以确保CodePipeline仅在特定分支上运行。

在CodePipeline中，您可以使用分支过滤器来限制您的流水线只在特定的分支上运行。您可以在流水线阶段中定义过滤器。下面是一个示例：

{
    "stages": [
        {
            "name": "Source",
            "actions": [
                {
                    "name": "Source",
                    "actionTypeId": {
                        "category": "Source",
                        "owner": "ThirdParty",
                        "provider": "GitHub",
                        "version": "1"
                    },
                    "outputArtifacts": [
                        {
                            "name": "MyApp"
                        }
                    ],
                    "runOrder": 1,
                    "configuration": {
                        "Owner": "my-org",
                        "Repo": "my-repo",
                        "Branch": "my-branch",
                        "OAuthToken": "",
                        "PollForSourceChanges": "true"
                    }
                }
            ]
        },
        {
            "name": "Build",
            "actions": [
                {
                    "name": "Build",
                    "actionTypeId": {
                        "category": "Build",
                        "owner": "AWS",
                        "provider": "CodeBuild",
                        "version": "1"
                    },
                    "inputArtifacts": [
                        {
                            "name": "MyApp"
                        }
                    ],
                    "outputArtifacts": [
                        {
                            "name": "MyAppBuild"
                        }
                    ],
                    "runOrder": 1,
                    "configuration": {
                        "ProjectName": "my-codebuild-project"
                    }
                }
            ]
        }
    ],
    "artifactStore": {
        "type": "S3",
        "location": ""
    },
    "name": "MyDeliveryPipeline",
    "roleArn": "",
    "version": 1,
    "pipeline": "my-pipeline",
    "disableInboundStageTransitions": false,
    "restartExecutionOnUpdate": false,
    "executionArn": "arn:aws:codepipeline:::"
}

在以上示例中，“Source”阶段的Git存储库允许使用分支过滤器。 configuration部分设置了分支名称“my-branch”。这将确保只有在匹配的分支上更改时才会触发流水线。
