Run GitLab CI for a subdirectory in the same project

Question

I have three subprojects (Angular and Node.js) in the same GitLab project. Now I want to create the gitlab-ci.yml file for building and deploying one of this subprojects. Can I create three different gitlab-ci.yml files and run them inside subdirectories? Is it possible? Or should I push those into three different projects?

Answer 1

My personal preference is to keep projects small. So I usually create one GitLab project per, e.g., module, library, program, design, etc.

But if you really wanted to, you could easily either:

• Create a single .gitlab-ci.yml that goes something like:

  my_job:
    stage: test
    script:
      - |
         cd "$CI_PROJECT_DIR/folder1"
         < do stuff >
         cd "$CI_PROJECT_DIR/folder2"
         < do stuff>
         ...
  

• Create multiple gitlab-ci configurations inside the folders and include them in the root .gitlab-ci.yml file

  include:
    - 'folder1/pipeline.yml'
    - 'folder2/pipeline.yml'
  

Note that when using the second option, you will still have to cd folderX since pipelines always start in the repository's root directory, no matter from where they are imported.
