You need to add a readinessProbe (just copy your livenessProbe).

It's explained in the GCE L7 Ingress Docs.

Health checks

Currently, all service backends must satisfy either of the following requirements to pass the HTTP health checks sent to it from the GCE loadbalancer: 1. Respond with a 200 on '/'. The content does not matter. 2. Expose an arbitrary url as a readiness probe on the pods backing the Service.

Also make sure that the readinessProbe is pointing to the same port that you expose to the Ingress. In your case that's fine since you have only one port, if you add another one you may run into trouble.
