How to execute a a remote script in a reusable github workflow

Question

I have this workflow in a repo called terraform-do-database and I'm trying to use a reusable workflow coming from the public repo foo/git-workflows/.github/workflows/tag_validation.yaml@master

name: Tag Validation

on:
  pull_request:
    branches: [master]
  push:
    branches:    
      - '*'         # matches every branch that doesn't contain a '/'
      - '*/*'       # matches every branch containing a single '/'
      - '**'        # matches every branch
      - '!master'   # excludes master
  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

jobs:

  tag_check:
    uses: foo/git-workflows/.github/workflows/tag_validation.yaml@master

And this is the reusable workflow file from the public git-workflows repo that has the script that should run on it. What is happening is that the workflow is trying to use a script inside the repo terraform-do-database

name: Tag Validation

on:
  pull_request:
    branches: [master]
  workflow_call:

jobs:

  tag_check:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v3

      # Runs a single command using the runners shell
      - name: Verify the tag value
        run: ./scripts/tag_verify.sh

So the question: How can I make the workflow use the script stored in the git-worflows repo instead of the terraform-do-database?

I want to have a single repo where I can call the workflow and the scripts, I don't want to have everything duplicated inside all my repos.

Answer 1

I was able to solve it adding a few more commands to manually download the script and execute it.

steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v3

      # Runs a single command using the runners shell
      - name: Check current directory
        run: pwd
      - name: Download the script
        run: curl -o $PWD/tag_verify.sh https://raw.githubusercontent.com/foo/git-workflows/master/scripts/tag_verify.sh
      - name: Give script permissions
        run: chmod +x $PWD/tag_verify.sh
      - name: Execute script
        run: $PWD/tag_verify.sh
