Kubernetes RollingUpdate - how to respect readinessProbe?

General Discussions

We have deployments with the following strategy:

      replicas: 6
      strategy:  
          type: RollingUpdate  
          RollingUpdate:  
            maxUnavailable: 1  
            maxSurge: 100%

The deployments also have readiness (and liveness) probes:

readinessProbe:  
            httpGet:  
              path: /  
              port: http  
            initialDelaySeconds: 30

The issue I am seeing is that Kubernetes instantly terminates the old replicas when doing an upgrade. It does not wait for the new pods to become ready before moving on.

What am I missing here?

Hi! Did you ever figure this out? If so, what is the solution?
