## Getting started

### (1) Add ssh deploy key

Generate your deploy key with the following command.

```sh
ssh-keygen -t rsa -b 4096 -C "$(git config user.email)" -f gh-pages -N ""
# You will get 2 files:
#   gh-pages.pub (public key)
#   gh-pages     (private key)
```

Next, Go to **Repository Settings**

- Go to **Deploy Keys** and add your public key with the **Allow write access**
- Go to **Secrets** and add your private key as `ACTIONS_DEPLOY_KEY`

### (2) Create `.github/workflows/gh-pages.yml`

#### :star: Repository type - Project

An example workflow for Hugo.

- [peaceiris/actions-hugo: GitHub Actions for Hugo](https://github.com/peaceiris/actions-hugo)

[![peaceiris/actions-hugo - GitHub](https://gh-card.dev/repos/peaceiris/actions-hugo.svg?fullname)](https://github.com/peaceiris/actions-hugo)

![peaceiris/actions-hugo latest version](https://img.shields.io/github/release/peaceiris/actions-hugo.svg?label=peaceiris%2Factions-hugo)
![peaceiris/actions-gh-pages latest version](https://img.shields.io/github/release/peaceiris/actions-gh-pages.svg?label=peaceiris%2Factions-gh-pages)

```yaml
name: github pages

on:
  push:
    branches:
    - master

jobs:
  build-deploy:
    runs-on: ubuntu-18.04
    steps:
    - uses: actions/checkout@master

    - name: Setup Hugo
      uses: peaceiris/actions-hugo@v2.1.0
      with:
        hugo-version: '0.58.2'

    - name: Build
      run: hugo --gc --minify --cleanDestinationDir

    - name: Deploy
      uses: peaceiris/actions-gh-pages@v2.3.1
      env:
        ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
        PUBLISH_BRANCH: gh-pages
        PUBLISH_DIR: ./public
```

The above example is for [Project Pages sites]. (`<username>/<project_name>` repository)

#### :star: Repository type - User and Organization

For [User and Organization Pages sites] (`<username>/<username>.github.io` repository),
we have to set `master` branch to `PUBLISH_BRANCH`.

```yaml
on:
  push:
    branches:
    - source  # default branch

PUBLISH_BRANCH: master  # deploying branch
```

[Project Pages sites]: https://help.github.com/en/articles/user-organization-and-project-pages#project-pages-sites
[User and Organization Pages sites]: https://help.github.com/en/articles/user-organization-and-project-pages#user-and-organization-pages-sites

### Options

#### :star: Pull action image from Docker Hub

You can pull a public docker image from Docker Hub.
By pulling docker images, you can reduce the overall execution time of your workflow. In addition, `latest` tag is provided.

```diff
- uses: peaceiris/actions-gh-pages@v2.3.1
+ uses: docker://peaceiris/gh-pages:v2.3.1
```

- [peaceiris/gh-pages - Docker Hub](https://hub.docker.com/r/peaceiris/gh-pages)

#### :star: `PERSONAL_TOKEN`

[Generate a personal access token (`repo`)](https://github.com/settings/tokens) and add it to Secrets as `PERSONAL_TOKEN`, it works as well as `ACTIONS_DEPLOY_KEY`.

```diff
- ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
+ PERSONAL_TOKEN: ${{ secrets.PERSONAL_TOKEN }}
```

#### :star: `GITHUB_TOKEN`

> **NOTES**: This action supports `GITHUB_TOKEN` but it has some problems to deploy to GitHub Pages. See #9

```diff
- ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
+ GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```

#### :star: Suppressing empty commits

By default, a commit will always be generated and pushed to the `PUBLISH_BRANCH`, even if nothing changed. If you want to suppress this behavior, set the optional parameter `emptyCommits` to `false`. cf. [Issue #21]

[Issue #21]: https://github.com/peaceiris/actions-gh-pages/issues/21

For example:

```yaml
- name: deploy
  uses: peaceiris/actions-gh-pages@v2.3.1
  env:
    ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
    PUBLISH_BRANCH: gh-pages
    PUBLISH_DIR: ./public
  with:
    emptyCommits: false
```


## Tips and FAQ

### How to add `CNAME`

Most of the Static Site Generators support `CNAME` as a static file.

- [Use a Custom Domain | Hugo](https://gohugo.io/hosting-and-deployment/hosting-on-github/#use-a-custom-domain)
- [Using the Static folder | GatsbyJS](https://www.gatsbyjs.org/docs/static-folder/)

The same may be said of other files (`.nojekyll`, `BingSiteAuth.xml`, `robots.txt`, etc.). It is better to manage those files by Static Site Generators.

### Deployment completed but you cannot read

Does your `PUBLISH_DIR` contain files or directories that name starts with an underscore? (`_modules`, `_sources` and `_next`, etc.)
GitHub Pages does not read those by default.
Please add `.nojekyll` file to `PUBLISH_DIR`.

- [Bypassing Jekyll on GitHub Pages - The GitHub Blog](https://github.blog/2009-12-29-bypassing-jekyll-on-github-pages/)

> It is now possible to completely bypass Jekyll processing on GitHub Pages by creating a file named `.nojekyll` in the root of your pages repo and pushing it to GitHub. This should only be necessary if your site uses files or directories that start with underscores since Jekyll considers these to be special resources and does not copy them to the final site.
