## 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@v2.0.0
      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
```
