Host on GitHub

GitHub provides free and fast static hosting over SSL for personal, organization, or project pages directly from a GitHub repository via its GitHub Pages service and automate development workflows and build with GitHub Actions.

Assumptions  

1. You have Git 2.8 or greater installed on your machine.
2. You have a GitHub account. Signing up for GitHub is free.
3. You have a ready-to-publish Hugo website or have at least completed the Quick Start.

Types of GitHub Pages  

There are two types of GitHub Pages:

• User/Organization Pages (https://<USERNAME|ORGANIZATION>.github.io/)
• Project Pages (https://<USERNAME|ORGANIZATION>.github.io/<PROJECT>/)

Please refer to the GitHub Pages documentation to decide which type of site you would like to create as it will determine which of the below methods to use.

GitHub User or Organization Pages  

As mentioned in the GitHub Pages documentation, you can host a user/organization page in addition to project pages. Here are the key differences in GitHub Pages websites for Users and Organizations:

1. You must use a <USERNAME>.github.io to host your generated content
2. Content from the main branch will be used to publish your GitHub Pages site

This is a much simpler setup as your Hugo files and generated content are published into two different repositories.

Build Hugo With GitHub Action  

GitHub execute your software development workflows. Everytime you push your code on the Github repository, Github Action will build the site automatically.

Create a file in .github/workflows/gh-pages.yml containing the following content (based on https://github.com/marketplace/actions/hugo-setup ):

name: github pages

on:
  push:
    branches:
      - main  # Set a branch to deploy

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2
        with:
          submodules: true  # Fetch Hugo themes (true OR recursive)
          fetch-depth: 0    # Fetch all history for .GitInfo and .Lastmod

      - name: Setup Hugo
        uses: peaceiris/actions-hugo@v2
        with:
          hugo-version: 'latest'
          # extended: true

      - name: Build
        run: hugo --minify

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./public

Use a Custom Domain  

If you’d like to use a custom domain for your GitHub Pages site, create a file static/CNAME. Your custom domain name should be the only contents inside CNAME. Since it’s inside static, the published site will contain the CNAME file at the root of the published site, which is a requirement of GitHub Pages.

Refer to the official documentation for custom domains for further information.
