GitHub Action In-line if - github-actions

Question

So I have the following workflow and its working perfectly. I now want to enhance it and when I am doing a PR to master, I want to set NETLIFY_DEPLOY_TO_PROD: false instead of it being true? Do I have to duplicate this all in a new workflow, or could do some inline if check of github.event_name === push ? true : false
name: 'Netlify Deploy'
on:
push:
branches: [ master ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- uses: jsmrcaga/action-netlify-deploy#master
with:
NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}
NETLIFY_SITE_ID: ${{ secrets.SITE_ID }}
NETLIFY_DEPLOY_MESSAGE: "${{ github.event.head_commit.message }}"
NETLIFY_DEPLOY_TO_PROD: true

Answer 1

You could set an environment variable to indicate if deploy to prod should happen, and change it depending on the event name:
name: Netlify Deploy
on:
push:
branches:
- master
pull_request:
branches:
- master
env:
DEPLOY: false
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- name: Deploy on pushes
if: github.event_name == 'push'
run: echo 'DEPLOY=true' >> "$GITHUB_ENV"
- uses: jsmrcaga/action-netlify-deploy#master
with:
NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}
NETLIFY_SITE_ID: ${{ secrets.SITE_ID }}
NETLIFY_DEPLOY_MESSAGE: ${{ github.event.head_commit.message }}
NETLIFY_DEPLOY_TO_PROD: ${{ env.DEPLOY }}

Answer 2

You want to use github action expressions for this as it's quicker and you don't need any other unnecessary steps. I would only use steps to run scripts when they are more complex in nature
Reference: https://docs.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions
Example 1: Trigger on push
- uses: jsmrcaga/action-netlify-deploy#master
with:
NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}
NETLIFY_SITE_ID: ${{ secrets.SITE_ID }}
NETLIFY_DEPLOY_MESSAGE: "${{ github.event.head_commit.message }}"
NETLIFY_DEPLOY_TO_PROD: ${{ github.event_name == 'push' }}
Example 2 & Solution: Trigger on push and branch is master
NOTE: You only need to check for branch master if you are planning to let this workflow run on other branches. Otherwise you can just use example 1 above that sets variable to true if event name is push only.
- uses: jsmrcaga/action-netlify-deploy#master
with:
NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}
NETLIFY_SITE_ID: ${{ secrets.SITE_ID }}
NETLIFY_DEPLOY_MESSAGE: "${{ github.event.head_commit.message }}"
NETLIFY_DEPLOY_TO_PROD: ${{ github.event_name == 'push' && contains(github.ref, 'master') }}
