retag and push

Publish a distribution

Actions are run from GitHub repos so we will checkin the packed dist folder.

Then run ncc and push the results:

$ npm run package
$ git add dist
$ git commit -a -m "prod dependencies"

Usage:

This action is a small wrapper around docker tag and docker push which allows you to use to split the build and the push into two steps. We use this so that we can run image security scans before we push images to any registries, like this:

name: test
on:
  # push:
  pull_request:
    types:
      - synchronize
      - opened
      - reopened

jobs:
  # Label of the container job
  tests:
    # Containers must run in Linux based operating systems
    runs-on: ubuntu-latest
    steps:
      # Downloads a copy of the code in your repository before running CI tests
      - name: Check out repository code
        uses: actions/checkout@v2
      - uses: actions/setup-go@v1
        with:
          go-version: '1.16'
      - name: Get Short SHA
        id: vars
        run: echo "::set-output name=sha_short::$(git rev-parse --short HEAD)"
      # build phase
