branch-based-secrets GitHub Action

This action makes it easy to use different secrets for different branches. It relies on the following naming scheme for secrets: <name>_<branch>.

Usage example

In a project with 2 branches, prod and dev, define the following secrets:

• SECRET_TOKEN_DEV
• SECRET_TOKEN_PROD

Step configuration:

      - uses: stampix/branch-based-secrets@v1
        with:
          secrets: SECRET_TOKEN

In turn, when running an action on a push to dev or a pull_request targeted at branch dev, this will define the following environment variables:

• SECRET_TOKEN_NAME=SECRET_TOKEN_DEV
• TARGET_BRANCH=dev
• TARGET_BRANCH_U=DEV

After the action runs, you can pass the correct secret to other steps:

        env:
          SECRET_TOKEN: ${{ secrets[env.SECRET_TOKEN_NAME] }}
