Hey Discord, the pipeline failed!

Cloudflare Worker which can be used as a middleware between Gitlab webhooks and Discord webhooks to send out custom discord messages when your projects pipeline failed.

Setup

1. Create a new Discord webhook in the desired notification channel and save the webhook url as a new secret named DISCORD_WEBHOOK
2. Choose a secret which will allow Gitlab to access to the worker and save it as a new secret named GITLAB_WEBHOOK_SECRET_TOKEN
3. Create a new KV store and change the wrangler.toml accordingly.
4. Create new KV pairs to configure the notifications (see configuration)
5. Create a new Gitlab webhook in the desired repository.
   1. URL: the deployment url of this worker
   2. Secret token: the chosen secret
   3. Trigger: disable all but Pipeline events
   4. SSL verification: true

Configuration

The configuration takes advantage of Cloudflare's key value store as each key in the configured kv store represents the notification configuration for one specific repository.

key: repository web url
value: {"branch_name": "notification text", ...}

for example:

key: https://gitlab.com/example-group/example-project
value: {"main": "<@&979396042485276733> Die Pipeline der Webseite für den main-Branch ist fehlgeschlagen!", ...}
