GitHub Action: Deploy GitHub Pages

A simple GitHub Action to deploy already generated static pages to GitHub Pages.

Inputs

• cname- If set, create a CNAME file with the provided value.
• defaultBranch - The default branch name for the repository, defaults to master for
  backwards-compatiblity reasons. Version 2.x will likely default to main.
• docsPath - The folder where the generated docs are located, defaults to docs.
• gitCommitEmail - The email to use when committing to the repository, defaults to the repository
  owner's fake GitHub email.
• gitCommitFlags - Any extra git commit flags to pass, such as --no-verify.
• gitCommitMessage - The commit message to use when creating/updating the GitHub Pages branch.
  Defaults to Publish.
• gitCommitUser - The value to set git config user.name, defaults to the repository owner.
• noCommit - If set, stage changes but do not commit them, defaults to false.
• publishBranch - The branch name that GitHub Pages uses to build the website, defaults
  to gh-pages.
• redirectURLSuffix - The path suffix for the redirect URL used in index.html, when
  versionDocs is true.
• showUnderscoreFiles - If set, adds a .nojekyll file to the root so files that start with
  _ are accessible.
• versionDocs- If set, put docs for all branches and tags in their own subfolders, defaults
  to false.

Secrets used

This action uses one of two methods to push the commit back up to the repository:

• If GH_PAGES_SSH_DEPLOY_KEY is specified in the repository secrets, it is used to push the
  commit back to the repository's SSH endpoint.
• Otherwise, GITHUB_TOKEN is used to push the commit back to the repository's HTTPS endpoint. This
  currently only works with private repositories. See the GitHub Actions forum post for details.

Example workflow

name: Publish Documentation

on: push

jobs:
  docs:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - run: git fetch --no-tags --prune --depth=1 origin +refs/heads/*:refs/remotes/origin/*
    - name: Build docs
    - run: make docs
    - name: Publish docs
      uses: malept/github-action-gh-pages@main
      with:
        gitCommitUser: Docs Publisher Bot
      env:
        DOCS_SSH_DEPLOY_KEY: ${{ secrets.DOCS_SSH_DEPLOY_KEY }}

In a production setting, main should be a tagged version (e.g., v1.0.0).

Debugging

If you need to debug the entrypoint.sh script, you can set the GH_PAGES_DEBUG environment variable, which sets -x in the shell script.
