Can’t see getting your workflow run on changing files in directories you have set track to ?

If you want to read about filter pattern, you can read @ here.

The path matchingin github actions is kind of so vagues coz:

on:
  push:
    branches:
      - main
    paths:
      - '.github/workflows/project-backend.yml'
      - './exercises/ex4-08/ex4-06/ex2-08-statefulsets/ex2-02/**'

above won’t work coz you have ./ in the begining of the exercises path and that causes it to not tract our desired folder, so instead, we must do like below (remove the ./) and it’ll work:

...
      - 'exercises/ex4-08/ex4-06/ex2-08-statefulsets/ex2-02/**'
...
