using variable and secrets in gitub calling workflow

Accessing variables

If you defined your variables via Github-> Settings-> Secret and Variable -> Variable, then you can reference it using ${{ vars.my_variable }}. Pretty straight forward. 

Accessing secrets 

Accessing secret is abit tricky for calling workflow. You need to declare the secrets to be used, like what is shown below

1. add secrets before calling the workflow 

  build-image:

    uses: mitzen/dotnet-gaction/.github/workflows/buildimage.yaml@main

    needs: build-project

    with:

      artifact: build-artifact

      repository: kepung

      tags: "dotnetaction"

     

    secrets:

      docker_username: ${{ secrets.DOCKERUSER}}

      docker_token: ${{ secrets.DOCKERUSER}}

2. Next, add the secret as parameter in the calling workflow and use it

on:

  workflow_call:

    secrets:

      docker_username:

        required: true

     

      docker_token:

        required: true

    inputs:

      artifact:

        required: true

        type: string

      repository:

        required: true

        type: string

     

      tags:

        required: true

        type: string

 

jobs:

 build-docker-image:

   runs-on: ubuntu-latest

   steps:

      -

        name: Checkout

        uses: actions/checkout@v3

      - name: run script

        run: |

           echo  ${{ secrets.docker_username}}

   

You will noticed we still reference it as secrets.docker_username.
