Bitbucket Pipeline配置：实现任意顺序部署至指定环境

我配置了如下Bitbucket Pipeline，希望能够选择部署的目标环境。当前设置下必须先部署至Dev环境，才能部署至QA环境，我希望可以任意顺序部署至其中任一环境，请问是否可行？我曾尝试为各环境设置并行步骤，但没有效果。

原Pipeline配置：

options:
  max-time: 5


image: node:latest

definitions: 
  steps:
    - step: &build
        name: Build
        caches:
          - node
        script:
          - Build Script
        artifacts:
         - *.zip
    - step: &deploy
        name: Deploy to Dev
        deployment: Dev
        trigger: manual
        runs-on:
         - self.hosted
         - windows
        script:
         - Deploy Script

pipelines:
  default:
    - parallel:
        - step: *build
    - step: *deploy
    - step:
          <<: *deploy
          name: Deploy to QA
          deployment: QA
          trigger: manual

完全可行，你需要调整Pipeline的步骤结构，把两个部署步骤放到同一个并行块中，同时保证它们都能获取到Build步骤生成的产物。修改后的配置如下：

options:
  max-time: 5

image: node:latest

definitions: 
  steps:
    - step: &build
        name: Build
        caches:
          - node
        script:
          - Build Script
        artifacts:
         - *.zip
    - step: &deploy-dev
        name: Deploy to Dev
        deployment: Dev
        trigger: manual
        runs-on:
         - self.hosted
         - windows
        script:
         - Deploy Script
    - step: &deploy-qa
        name: Deploy to QA
        deployment: QA
        trigger: manual
        runs-on:
         - self.hosted
         - windows
        script:
         - Deploy Script

pipelines:
  default:
    - step: *build
    - parallel:
        - step: *deploy-dev
        - step: *deploy-qa

核心调整点： #

• 先单独执行Build步骤，确保它生成的部署产物（artifacts）能被后续步骤访问
• 将Dev和QA的部署步骤移入同一个parallel块，这样两者就不再有强制的先后执行顺序
• 两个部署步骤都保留trigger: manual，你可以在Pipeline运行时自由选择触发其中一个，或者按任意顺序触发两个
• 因为并行块在Build步骤之后执行，所以两个部署步骤都能正常获取到Build生成的文件

这样修改后，你就可以不受顺序限制，直接选择部署到Dev或QA环境了。
