circleci - 如何在 CircleCI 步骤之间传递动态参数

Question

我将在 CircleCI 作业的第一步中生成一个 UID。有没有办法将此值存储为可供后续步骤访问的“管道参数”？另外，有没有办法在作业之间传递此类动态参数？

类似这样的事情

jobs:
    build:
        steps:
            - run:
                name: Generate UID
                command: |
                    UID=$(date +%s)
                    << pipeline.parameters.UID >> = UID # Store UID in the job context

            - run:
                name: Run Tests
                command: |
                    UID = << pipeline.parameters.UID >> # Retrieve UID from the job context
                    ./do_something.sh ${UID}
                    

我似乎无法在 CircleCI 文档中找到确切的答案。看过

• https://circleci.com/docs/reusing-config#parameter-syntax
• https://circleci.com/docs/env-vars#setting-an-environment-variable-in-a-job

我可能已经接近解决方案，但我感到陷入困境并感谢任何帮助。

Answer 1

您可以使用临时环境。要写入和读取的变量:

steps:  
  -  run:  
    name: Post release to GitHub repo 
    command:  |  
     set -e 
     rel_id=$(./scripts/post-internal-release.sh) 
     echo "export REL_ID='$rel_id'" >> $BASH_ENV

读回它:

run:  
  name: Upload mapping files to github 
  command:  |  
  ./scripts/upload_mapping_to_github.sh ${REL_ID}
