Authenticating to the GitHub API using a GitHub App is slightly more complicated than using a PAT but it is a more secure method.

In order to make this easier in ruby application this gem includes executables that can generate an authentication token or dispatch a GitHub event.

You must configure your GitHub App following the instructions here.

You should ensure that the following ENV variables are set:

• CLIENT_ID
• GITHUB_INSTALLATION_ID
• GITHUB_PRIVATE_KEY_B64 - the base 64 encoded private key.

ruby -Ilib ./bin/generate_token

Set the private key to an ENV variable:

$ export MY_KEY="----BEGIN RSA..."

$ export ENCODED_KEY=(echo $MY_KEY | base64)
