Pod TTL Controller

Pod TTL Controller is a controller to manage pod TTLs. TTL == Time-To-Live.

There are some use cases where a Pod should not live longer than a given threshold.

One such use case is Docker registry "corrupting" it's cache every 7 days. :)

Running the controller

Check out the deploy folder. It has all the needed components to run the controller.

Enabling TTL on Pods

The Pod TTL Controller uses Pod annotations to trigger the TTL functionality. So the example Pod that would live for 5 minutes would look like:

kind: Pod
apiVersion: v1
metadata:
  name: ttl-pod
  labels:
    name: ttl-pod
  annotations:
    nummel.in/pod-ttl: "300"
spec:
  containers:
  - name: ttl-pod
    image: nginx
    ports:
      - containerPort: 80

When the operator sees the pod ready, i.e. all the containers are up-and-running, it'll start a timer with the given ttl time. When the timer expires, the operator will go and delete the pod.
