问题描述
我的CodePipeline中有两个不同的来源，ECR和S3.我的部署管道将zip上传到S3，然后将图像上传到ECR.
I have two different sources in my CodePipeline, ECR and S3. My deployment pipeline uploads a zip to S3, and then an image to ECR.
我需要CodePipeline仅检测最后一次发生的ECR提交，然后触发S3源操作.但是，无论哪个首先被检测到，都会启动CodePipeline，这会导致竞争状态，在该状态下尚未上传新版本的图像.
I need CodePipeline to detect just the ECR commit, which happens last, and then trigger the S3 source action. However whichever one is detected first starts the CodePipeline, which leads to a race condition in which the image for the new version hasn't been uploaded yet.
我该如何解决?根据CodePipeline的限制，我无法将S3移出Source阶段.我曾尝试将S3下载移至Lambda函数，但似乎无法将zip作为输出工件传递回CodePipeline.
How can I resolve this? I cannot move S3 out of the Source stage, as per CodePipeline limitations. I've tried moving this S3 download to a Lambda function, but I can't seem to pass the zip back to CodePipeline as an output artifact.
推荐答案
作为要运行的CodePipeline的触发器，请仅为ECR定义CloudWatch事件触发器，而不为S3更改定义CloudWatch事件触发器.禁用管道内置触发器/拉动.
As trigger for the CodePipeline to run, define the CloudWatch event trigger only for ECR, not for S3 changes. Disable the Pipeline built-in trigger/pull.
https://docs.aws.amazon.com/codepipeline/latest/userguide/create-cwe-ecr-source-console.html 这样可以确保只有ECR触发管道执行.
https://docs.aws.amazon.com/codepipeline/latest/userguide/create-cwe-ecr-source-console.htmlThis will make sure only ECR triggers a pipeline execution.
