gitlab-ci - 动态设置gitlab-ci cache.key

Question

有一种方法可以动态设置缓存:key:，如下所示:

cache:
    key: if $CI_PIPELINE_SOURCE -eq 'merge_request_event' { "MR_$CI_MERGE_REQUEST_TRAGET_BRANCH_NAME_CACHE" } else { "PUSH_$CI_COMMIT_REF_NAME_CACHE" }

或者也许有一种方法可以动态定义 pipile 变量:

variables:
    CACHE_KEY: if $CI_PIPELINE_SOURCE -eq 'merge_request_event' { "MR_$CI_MERGE_REQUEST_TRAGET_BRANCH_NAME_CACHE" } else { "PUSH_$CI_COMMIT_REF_NAME_CACHE" }                            

cache:
    key: $CACHE_KEY

您正在寻找的是 rules check ，就像这样:

  variables:
    //Your default value
    CACHE_KEY: "PUSH_$CI_COMMIT_REF_NAME_CACHE"
  rules:
    - if: if $CI_PIPELINE_SOURCE == 'merge_request_event'
      //Override based on the above condition 
      variables:
        CACHE_KEY: "MR_$CI_MERGE_REQUEST_TRAGET_BRANCH_NAME_CACHE"
