EXPERIMENTAL: This is a gateway for exposing Trello-compatible webhooks to Brigade. It is not ready for production use (namely, the payload validation is not done yet).

To use this gateway, you will need:

• A Kubernetes cluster
  • running Brigade
  • with Helm
• A Trello account, along with the developer token and apikey
• At least one Trello board

Trello API docs: https://developers.trello.com/

Clone this repo and install the Helm chart:

$ helm install -n brigade-trello charts/brigade-trello

You probably want to enable either Ingress or LoadBalancer

$ helm install -n brigade-trello charts/brigade-trello --set service.type=LoadBalancer

You may also want to enabled RBAC with --set rbac.enabled=true.

Once the gateway is installed and exposed on a public IP address, you will need to register a Webhook gateway with Trello. This is a manual process described in the Trello docs.

The webhook URL should take the form:

https://<GATEWAY_IP_OR_NAME>/trello/<PROJECT_ID>

(substitute https if your ingress or service is configured for TLS)

Note that the PROJECT_ID is of the form brigade-XXXXXXXXXXXXXXXXXXXX, not the human-readable name.

We highly recommend registering a webhook for a single board until you get the hang of using this gateway.

There is a highly experimental "generic webhook" implementation in this gateway as well. You can use this to run arbitrary webhooks, but it is insecure by design (since it does not seek to validate the identy of the sender or the payload). It is at https://<HOST>/webhook/<PROJECT_ID>.

Note: While the above URLs respond to GET and HEAD requests, it will always respond with a no-op 200-level request. Only POST can be used to actually trigger an event.

This gateway emits two Brigade events:

• trello: The event triggered any time a Trello event fires.
• webhook: (EXPERIMENTAL) Triggered if you use the experimental /generic/<PROJECT> endpoint. This hook is considered untrusted and should be treated with utmost caution.

A brigade.js that makes use of the trello hook can be found in the repository. In a nutshell, though, they look like this:

events.on("trello", (e, p) => {
  // Parse the JSON payload from Trello.
  var hook = JSON.parse(e.payload)
  // Now you can go about your business.
})

The Trello JSON format is described in their docs

$ make build
