Label Kubernetes Pods

This binary will read kubernetes configuration by checking default locations for kubectl and then apply the deploy=groupN label to all pods that feature the app=sfu label.

There are four groups currently:

• group1 will be applied to ~10% of pods
• group2 will be applied to ~30% of pods
• group3 will be applied to ~30% of pods
• group4 will be applied to the rest of pods (~30%)

Rationale

We are using a statefulSet deployment in combination with OnDelete update strategy.

To delete the deployment in batches we are applying labels, splitting pods in groups.
