Question

I have one repo it has 3 yaml files for frontend, backend & admin frontend. Developer push on backend works on every time. My 3 yamls running but frontend & admin frontend folder code have no changes in that time i need only backend yaml only run remaining two yaml simply do nothing,

For my scenario if user pushes to backend code only backend ci only i need to run

How to configure that?

You can achieve what you want by using the paths subtype in each of your workflow triggers.

I recommend to check the Github official documentation for more details.

In your case, supposing that you have 3 folders following the structure below:

repository
    |__ backend
    |__ frontend
    |__ admin_fronted

For each workflow, you could user the following implementation:

name: Backend

on:
  push:
    paths:
      - 'backend/**'

jobs:
   [ ... ]

name: Frontend

on:
  push:
    paths:
      - 'frontend/**'

jobs:
   [ ... ]

name: Admin Frontend

on:
  push:
    paths:
      - 'admin_frontend/**'

jobs:
   [ ... ]

That way, each push will trigger a workflow only if at least a file in the specific path has been updated.

Note that there is also a paths-ignore subtype when you can use the opposite behavior if needed.
