This is a simple demo of an ACR webhook to automatically upgrade a Helm chart. The
brigade.js is configured to upgrade a Helm release every time the specified
Docker image is upgraded in an Azure Container Registry (ACR).
This is not production quailty. It is a demo.
To use this demo, you will need to point it to your own ACR repository. To do this, you will need to edit the registry in the following places:
Then you will need to configure your ACR to trigger a webhook on each push event.
Note: With a little bit of modification to the
brigade.js, you can also
use this for DockerHub webhooks.
- Helm and Brigade must be installed on your cluster
- Your cluster must have a routable IP attached to the
- You must have an ACR created with type
- You need a clone of this repository
- You need to configure a Slack incomming webhook. See Slack-Notify
You can either use the
az acr webhook tool or use the
webhooks panel in the
Container Registry section of the Azure portal. You must configure the webhook
to point to the Brigade gateway.
To get the external IP of the gateway, do:
$ kubectl get svc | brigade-gw
Set up your webhook to use
- The IP is the gateway IP from the command above (or a DNS address, if you set one up)
- Project name is the name of your Brigade project (
- Commit is the commit/branch/repo in the repo you want to use to fetch the brigade.js from, usually
So if project name is
technosophos/hello-helm, and the host is
the URL would be something like:
Configuring your Brigade project
If this is the first time you have used the Slack Notifier webhook, you need to add the Slack incomming webhook URL to your project.
Typically, you will want to edit the project's
values.yaml overrides. But here's how to do it
from the Helm commandline:
$ helm upgrade myproject brigade/brigade-project --set secrets.SLACK_WEBHOOK=https://rest/of/url
How it works
make docker-build docker-pushpushes a new image
- ACR responds to the push by calling the webhook
- The webhook triggers a brigade event
- The brigade event handler causes Helm to upgrade the chart with the new label
You can update the new build by running:
$ VERSION=0.1.2 make docker-build docker-push
The above will create a new tag for the image (
0.1.2), which will trigger a
