Gated steps with GitHub Actions

The workflow_dispatch event allows us to manually trigger a build with given parameters.

1. Add the deploy.sh script that will run in the pipeline

   if [ ${DEPLOY:-"false"} == "true" ]
   then
       echo "deploying!"
   fi

   • Will only deploy if DEPLOY is set to "true"

2. Add the workflow_dispatch event to the pipeline .github/workflows/pipeline.yml

   name: pipeline
   on:
       push:
           branches:
               - master
       workflow_dispatch:
           inputs:
               deploy:
                   description: deploy
                   required: true
                   default: "true" 
   jobs:
       pipeline:
           runs-on: ubuntu-latest
           steps:
               - uses: actions/checkout@v2
               - name: deploy
                   env:
                       DEPLOY: ${{ github.event.inputs.deploy }}
                   run: |
                       sh ./deploy.sh

3. Trigger the workflow_dispatch event through the UI
