# GitHub Actions workflow: Builds the site and uploads it to the target server.
#
# For more details on workflows, see README.md.
#
# See also: https://gohugo.io/hosting-and-deployment/hosting-on-github/
#
name: Build and Deploy
# When to run this workflow
#
# See: https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows
# See: https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#on
#
# TIP: Don't use "schedule" triggers as this will cause the workflow to be disabled after 60 days of inactivity
# (and afterward the workflow must be manually reenabled).
on:
# Trigger the workflow on push to the main branch (deploy to production).
push:
branches:
- main
# NOTE: The preview branch is for tests without pull request (as GitHub Action sometimes work differently for pushes
# and pull requests).
- preview
# Trigger the workflow for any pull requests (deploy to preview, if "local" PR; don't deploy if PR from fork).
pull_request:
# Allow manual run of this workflow (https://docs.github.com/en/actions/using-workflows/manually-running-a-workflow)
workflow_dispatch:
# Permissions for GITHUB_TOKEN for this workflow.
#
# See: https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token
#
# NOTE: Because we run with minimal permissions, we use "@vX" (instead of "@hash") for non-GitHub steps below.
# Usually you would use "@hash" as a security measure to pin a specific version. However, since we run with
# minimal permissions here, malicious code can't do much harm (most likely). For more details, see:

# The Hugo version to use: https://github.com/gohugoio/hugo/releases
# NOTE: It sometimes happens that new Hugo versions break the site. So I've decided to always
# "pin" the Hugo version (instead of using the latest version). This way, the Hugo version
# can be updated with a pull request where I can test the new version.
# IMPORTANT: Always USE A PULL REQUEST TO UPDATE THE HUGO VERSION to be able to fix all problems
# before pushing the result to production!!!
