GitHub Action
Use App token
Run GitHub Actions as a GitHub App by using the app's authentication token
This GitHub Action can be used to impersonate a GitHub App when secrets.GITHUB_TOKEN
's limitations are too restrictive and a personal access token is not suitable. secrets.GITHUB_TOKEN
has limitations such as not being able to triggering a new workflow from another workflow. A workaround is to use a personal access token from a personal user/bot account. However, for organizations, GitHub Apps are a more appropriate automation solution.
We can also use an app token to custom an action's name and avatar.
Before staring, we should get the "APP ID" and "Private Key" in the app's setting page. For example, find the two values in my app's setting page https://github.com/settings/apps/wow-actions-bot.
Get the app's "APP ID"
Get or create a "Private Key"
Do not have a Github App? Get a quick start with probot.
Then add "APP ID" and "Private Key" to the target repo's secrets. For example, we can add two secrets named APP_ID
and PRIVATE_KEY
with corresponding values.
Now we can config our workflows.
