Publishing Subdirectory to Github Pages

I’m using Hugo + Github Pages as my personal blog platform. A Hugo site yields the following directory structure, where the public/ subdirectory stores the generated static pages:

├── archetypes/
├── config.toml
├── content/
├── data/
├── layouts/
├── public/
├── resources/
├── static/
└── themes/

How do I publish the public/ subdirectory, instead of the root directory, to Github Pages?

We need two branches to achieve this. Assuming your default publishing source is the gh-pages branch (check out this link for more information about default publishing source), we commit the entire Hugo site to the master branch, and commit only the public/ subdirectory to the gh-pages branch. Here are the steps:

1. Commit public/ to master branch. You need first make sure it isn’t ignored by Git.
2. Push only public/ to gh-pages branch: git subtree push --prefix public origin gh-pages.

This should do the trick.
