在AWS::CodePipeline::Pipeline中添加更多分支，以在每次推送两个特定分支时启动管道

Question

我创建了一个堆栈，其中有用于创建管道的资源，每次在"；主"；分支启动了管道：

CodeCommitBranch:
Type: String
Description: branch name
Default: master
AllowedValues:
- develop
- release
- master
CodePipeline:
Type: 'AWS::CodePipeline::Pipeline'
Properties:
Name: !Sub '${Constructor}-${ApplicationID}-codepipeline'
ArtifactStore:
Location: !Ref CodePipelineS3BucketName
Type: S3
RestartExecutionOnUpdate: true
RoleArn: !Sub 'arn:aws:iam::${AWS::AccountId}:role/${CodePipelineRoleName}'
Stages:
- Name: Source
Actions:
- Name: Source
ActionTypeId:
Category: Source
Owner: AWS
Provider: CodeCommit
Version: 1
RunOrder: 1
OutputArtifacts:
- Name: SourceArtifact

BranchName: !Ref CodeCommitRepoBranch
PollForSourceChanges: false
RepositoryName: !GetAtt

我想知道当"推送"发生时，是否有可能在启动同一管道的同一资源中添加一个操作；开发"；树枝因此，最终管道在两种情况下都启动；主"；并且在"；开发"；。

Answer 1

AWS CodePipeline还不支持多分支管道配置。因此，理想情况下，您需要为develop分支创建另一个管道。

您的管道配置了CloudWatch事件。CloudWatch event rule会自动为您的管道配置

{
"source": [
"aws.codecommit"
],
"detail-type": [
"CodeCommit Repository State Change"
],
"resources": [
"arn:aws:codecommit:us-west-2:80398EXAMPLE:MyTestRepo"
],
"detail": {
"referenceType": [
"branch"
],
"referenceName": [
"master",
"develop"
]
}
}

如果以上事件规则是用您的管道配置的，那么它会触发master和develop分支更改。但是您的管道是为主分支配置的。因此，在CodeBuild中，您的主分支内容将在CODEBUILD_SRC_DIR位置中可用

CODEBUILD_SRC_DIR CODEBUILD用于生成的目录路径(例如，/tmp/src12345689/src(。

要为两个分支使用单个管道，则需要在buildspec.yml文件中开发并添加自己的逻辑，以签出到开发分支，然后在那里执行构建。

通常您不会尝试为多个分支使用同一管道进行构建。触发器是对分支的推送，该分支触发一个Cloud Watch事件，该事件反过来启动管道的其余部分。因此，从许多不同的分支尝试踢开管道是不好的。
