This GitHub Action allows you to run envsubst against a file/list of files, with optional pattern specificity.

Relies on your workflow job running in a Linux VM and therefore does not use docker containers.

steps:
  - name: Inject version number into files
    uses: dominicwatson/github-action-envsubst@v1
    with:
      files: manifest.json package.json static/bundle.mf
      patterns: $VERSION_NUMBER
    env:
      VERSION_NUMBER: ${{ steps.anotherstep.outputs.version_number }}

Required. One or more files, separated by a space, that will have envsubst performed on them.

Optional. Restrict the substitution to a strict set of patterns, rather than attempting to match any patterns found. Patterns separated by a space.
