action-github-app-token

This uses GitHub Apps to fetch a GitHub auth token for a GitHub App installation.
The GitHub App is used to authorize API access across multiple repositories.

Development

Install the dependencies
``bash
$ yarn
`

Build the typescript and package it for distribution
`bash
$ yarn build
`

Usage

You will need to provide the GitHub App ID and private key. The action will then provide a token output.

`
- name: my-app-install token
id: my-app
uses: 'getsentry/action-github-app-token'
with:
app_id: ${{ secrets.APP_ID }}
private_key: ${{ secrets.APP_PRIVATE_KEY }}

- name: Checkout private repo
uses: actions/checkout@v2
with:
repository: getsentry/my-private-repo
token: ${{ steps.my-app.output.token }}
