EVE

A bot to notify Slack users when their GitHub changes have been deployed on Heroku

Running

1. Create a GitHub App at https://github.com/settings/apps/new.
   • Uncheck the Webhook "Active" checkbox
   • Enable "Read-only" access to the "Contents" repository permission. This allows Eve to compare commits.
2. Download a private key to authenticate as the GitHub App
3. Create a Slack App at https://api.slack.com/apps.
   • Configure "Permissions" and add the "Bot Token Scopes" of chat:write and im:write
   • Install the app via "Install App to Workspace" and copy "Bot User OAuth Access Token"
4. Create a Heroku auth token.

   heroku authorizations:create -d 'eve credentials' -s read-protected
   

5. Run Eve

Deployment to Heroku

1. Create a Heroku app
2. Initialize your Heroku app: heroku git:remote -a my-app-name
3. Add the Rust buildpack: heroku buildpacks:set emk/rust
4. Push your app to Heroku: git push heroku master
5. Configure environment variables via the dashboard or heroku config:set KEY=VALUE
6. Finished. You could add the app url as a Heroku Post Deploy Hook, like https://my-app-name.herokuapp.com/heroku_deploy_hook?auth_token=my-secret-key.
