如何在云构建 yaml 文件中指定默认云运行修订版 url

通常你可以这样做（见步骤 id: tag ）

  - name: gcr.io/cloud-builders/docker
    args:
      - build
      - '--no-cache'
      - '-t'
      - '$_GCR_HOSTNAME/$PROJECT_ID/$REPO_NAME/$_SERVICE_NAME:$COMMIT_SHA'
      - .
      - '-f'
      - Dockerfile
    id: Build
  - name: gcr.io/cloud-builders/docker
    args:
      - push
      - '$_GCR_HOSTNAME/$PROJECT_ID/$REPO_NAME/$_SERVICE_NAME:$COMMIT_SHA'
    id: Push
  - name: 'gcr.io/google.com/cloudsdktool/cloud-sdk:slim'
    args:
      - run
      - services
      - update
      - $_SERVICE_NAME
      - '--platform=managed'
      - '--image=$_GCR_HOSTNAME/$PROJECT_ID/$REPO_NAME/$_SERVICE_NAME:$COMMIT_SHA'
      - >-
        --labels=managed-by=gcp-cloud-build-deploy-cloud-run,commit-sha=$COMMIT_SHA,gcb-build-id=$BUILD_ID,gcb-trigger-id=$_TRIGGER_ID,$_LABELS
      - '--region=$_DEPLOY_REGION'
      - '--quiet'
    id: Deploy
    entrypoint: gcloud
  - name: 'gcr.io/google.com/cloudsdktool/cloud-sdk:slim'
    args:
      - -c
      - |
         export sha=$COMMIT_SHA
         export CUSTOM_TAG=${sha:0:8}
         export CURRENT_REV=$(gcloud alpha run services describe $_SERVICE_NAME --region=$_DEPLOY_REGION --platform=managed --format='value(status.traffic[0].revisionName)')
         gcloud run services update-traffic $_SERVICE_NAME --set-tags=$$CUSTOM_TAG=$$CURRENT_REV --region=$_DEPLOY_REGION --platform=managed
    id: tag
    entrypoint: bash
images:
  - '$_GCR_HOSTNAME/$PROJECT_ID/$REPO_NAME/$_SERVICE_NAME:$COMMIT_SHA'
options:
  substitutionOption: ALLOW_LOOSE
substitutions:
  _PLATFORM: managed
  _SERVICE_NAME: bordereau
  _DEPLOY_REGION: europe-west1
  _LABELS: gcb-trigger-id=((a long random id goes here))
  _TRIGGER_ID: ((an other long random id goes here))
  _GCR_HOSTNAME: eu.gcr.io
tags:
  - gcp-cloud-build-deploy-cloud-run
  - gcp-cloud-build-deploy-cloud-run-managed
  - bordereau

在那个自定义标签中，我把提交 SHA 的第一个字符 8

您可以注意到奇怪的环境变量 COMMIT_SHA 复制到本地环境变量。 CloudBuild 很奇怪。
