## GitHub Actions for GitHub Pages

This is a **GitHub Action** to deploy your static files to **GitHub Pages**.
This deploy action can be combined simply and freely with [Static Site Generators]. (Hugo, MkDocs, Gatsby, GitBook, mdBook, etc.)

[Static Site Generators]: https://www.staticgen.com/

The next example step will deploy `./public` directory to the remote `gh-pages` branch.


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

### Supported Tokens

Three tokens are supported.

| Token | Private repo | Public repo | Protocol | Setup |
|---|:---:|:---:|---|---|
| `github_token` | ✅️ | ✅️ | HTTPS | Unnecessary |
| `deploy_key` | ✅️ | ✅️ | SSH | Necessary |
| `personal_token` | ✅️ | ✅️ | HTTPS | Necessary |

### Supported Platforms

| runs-on | `github_token` | `deploy_key` | `personal_token` |
|---|:---:|:---:|:---:|
| ubuntu-18.04 | ✅️ | ✅️ | ✅️ |
| macos-latest | ✅️ | ✅️ | ✅️ |
| windows-latest | ✅️ | (2) | ✅️ |

## Getting started

### ⭐️ Repository type - Project

Add your workflow file `.github/workflows/gh-pages.yml` and push to the remote master branch.

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)

```yaml
name: github pages

on:
  push:
    branches:
      - master

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v1
        # with:
        #   submodules: true

      - name: Setup Hugo
        uses: peaceiris/actions-hugo@v2
        with:
          hugo-version: '0.64.0'

      - name: Build
        run: hugo --minify

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

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

| Actions log overview | Build step log |

| ![](./images/log1.jpg) | ![](./images/log2.jpg) |

| Deploy step log | GitHub Pages log |
|---|---|
| ![](./images/log3.jpg) | ![](./images/log4.jpg) |

### ⭐️ 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`.

A default value of `publish_branch` is `gh-pages`.

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

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2

      - run: somebuild

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./public
          publish_branch: master  # deploying branch
```

## Options

### ⭐️ `deploy_key`

Read [⭐️ Create SSH Deploy Key](#%EF%B8%8F-create-ssh-deploy-key), create your SSH deploy key, and set the `deploy_key` option like the following.

```yaml
- name: Deploy
  uses: peaceiris/actions-gh-pages@v3
  with:
    deploy_key: ${{ secrets.ACTIONS_DEPLOY_KEY }}
    publish_dir: ./public
```

### ⭐️ `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`.


```yaml
- name: Deploy
  uses: peaceiris/actions-gh-pages@v3
  with:
    personal_token: ${{ secrets.PERSONAL_TOKEN }}
    publish_dir: ./public
```

### ⭐️ CNAME

To add `CNAME` file, we can set the `cname` option.

For more details about `CNAME`, read the official documentation: [Managing a custom domain for your GitHub Pages site - GitHub Help](https://help.github.com/en/github/working-with-github-pages/managing-a-custom-domain-for-your-github-pages-site)

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

### ⭐️ Disable `.nojekyll`

By default, this action adds the `.nojekyll` file to only the `master` and `gh-pages` branches. When the file already exists, this action does nothing.

To disable this behavior, we can set the `disable_nojekyll` option to `true`.

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

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

### ⭐️ Allow empty commits

By default, a commit will not be generated when no file changes. If you want to allow an empty commit, set the optional parameter `allow_empty_commit` to `true`.

For example:

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

### ⭐️ Keeping existing files

By default, existing files in the publish branch are removed before adding the ones from publish dir. If you want the action to add new files but leave existing ones untouched, set the optional parameter `keep_files` to `true`.

For example:

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

### ⭐️ Deploy to external repository

By default, your files are published to the repository which is running this action.
If you want to publish to another repository on GitHub, set the environment variable `external_repository` to `<username>/<external-repository>`.

For example:

```yaml
- name: Deploy
  uses: peaceiris/actions-gh-pages@v3
  with:
    deploy_key: ${{ secrets.ACTIONS_DEPLOY_KEY }}
    external_repository: username/external-repository
    publish_branch: master
    publish_dir: ./public
```

You can use `deploy_key` or `personal_token`.
When you use `deploy_key`, set your private key to the repository which includes this action and set your public key to your external repository.

Be careful, `GITHUB_TOKEN` has no permission to access to external repositories.

### ⭐️ Force orphan

We can set the `force_orphan: true` option.
This allows you to make your publish branch with only the latest commit.

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

### ⭐️ Set Git username and email

Set custom `git config user.name` and `git config user.email`.
A commit is always created with the same user.

```yaml
- name: Deploy
  uses: peaceiris/actions-gh-pages@v3
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    publish_dir: ./public
    user_name: iris
    user_email: iris@peaceiris.com
```

### ⭐️ Set custom commit message

Set custom commit message.
When we create a commit with a message `docs: Update some post`, a deployment commit will be generated with a message `docs: Update some post ${GITHUB_SHA}`.

```yaml
- name: Deploy
  uses: peaceiris/actions-gh-pages@v3
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    publish_dir: ./public
    commit_message: ${{ github.event.head_commit.message }}
```

### ⭐️ Create Git tag

Here is an example workflow.

```yaml
name: github pages

on:
  push:
    branches:
      - master
    tags:
      - 'v*.*.*'

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2

      - name: Some build

      - name: Prepare tag
        id: prepare_tag
        if: startsWith(github.ref, 'refs/tags/')
        run: |
          TAG_NAME="${GITHUB_REF##refs/tags/}"
          echo "::set-output name=tag_name::${TAG_NAME}"
          echo "::set-output name=deploy_tag_name::deploy-${TAG_NAME}"

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./public
          tag_name: ${{ steps.prepare_tag.outputs.deploy_tag_name }}
          tag_message: 'Deployment ${{ steps.prepare_tag.outputs.tag_name }}'
```

Commands on a local machine.

```console
$ # On the master branch
$ git tag -a "v1.2.3" -m "Release v1.2.3"
$ git push origin "v1.2.3"

$ # After deployment
$ git fetch origin
$ git tag
deploy-v1.2.3  # Tag on the gh-pages branch
v1.2.3         # Tag on the master branch
```

## Tips and FAQ

### ⭐️ Create 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`

| Add your public key | Success |
|---|---|
| ![](./images/deploy-keys-1.jpg) | ![](./images/deploy-keys-2.jpg) |

| Add your private key | Success |
|---|---|
| ![](./images/secrets-1.jpg) | ![](./images/secrets-2.jpg) |

### ⭐️ Use the latest and specific release

We recommend you to use the latest and specific release of this action for stable CI/CD.
