k8s-publisher

A simple kubernetes controller that watches pods for any changes and notify to sinks or trigger actions based on pods annotations

The idea behind k8s-publisher is to empower pod level custom channels, and avoid a super sink to aggregate all events of a kubernetes cluster. And make it easy a pod diagnostic in case of naive errors.

Slack integration

The very first integration is with slack. You can define a slack channel to subscribe for a pod.

annotations:
  # Tell k8s-publisher to send notifications of failure to slack #my-channel
  notify-channels: |
        [{"type":"slack", "value":"#my-channel"}]

And the k8s-publisher takes care of publishing messages related to the pod to that channel.

Http integration

The very first integration is with slack. You can define a slack channel to subscribe for a pod.

annotations:
  # Tell k8s-publisher to send notifications of failure to endpoint
  notify-channels: |
        [{"type":"http", "value":"http://myendpoint.com/webhook"}]

And the k8s-publisher takes care of publishing messages related to the pod to that channel.

Installation

git clone https://github.com/zmalik/k8s-publisher.git

edit the deploy/deployment.yaml file and add your slack-api-token

kubectl create -f deploy/deployment.yaml

A k8s-publisher pod will run and keep an eye on all pods and keep checking for the notify-channels annotation.

Work in Progress

This is a work in progress to add more integrations like stdout or email.
