🧑‍💻 Usage

A GitHub App installation token can be created by the GitHub App id, the installation id and the private key like described in the docs.

To create an installation token with ghapp the private key can be injected via file or as environment variable.

The GitHub App id and installation id can be passed as flags or environment variables.

# load private key from file
ghapp token --id 123 --install-id 123456 --private-key-file .ghapp-private-key.pem

# load private key from environment variable
export GHAPP_PRIVATE_KEY=$(cat .ghapp-private-key.pem)
ghapp token --id 123 --install-id 123456

A usage on GitHub Actions could look like the following.

- id: setup-ghapp
  run: |
    curl -L "https://github.com/jhagestedt/ghapp/releases/latest/download/ghapp_linux_amd64" -o ./usr/local/bin/ghapp
    chmod +x ./usr/local/bin/ghapp
- id: ghapp-install-token
  run: |
    GHAPP_INSTALL_TOKEN=$(ghapp token)
    echo "::set-output name=ghapp_install_token::${GHAPP_INSTALL_TOKEN}"
  env:
    GHAPP_ID: 123
    GHAPP_INSTALL_ID: 123456
    GHAPP_PRIVATE_KEY: ${{ secrets.GHAPP_PRIVATE_KEY }}

🐳 Docker

There is also a docker container published at Dockerhub that contains the binary that can be used with docker run to not install it locally.

export GHAPP_PRIVATE_KEY=$(cat .ghapp-private-key.pem)
docker run --rm -e GHAPP_PRIVATE_KEY jhagestedt/ghapp token --id 123 --install-id 123456
