Issues while connecting containers in different Google Cloud clusters

9/6/2017

I have two clusters at Google Cloud Kubernetes.

The two clusters have different version. Cluster A is 1.6.4 and B is 1.6.7. When they were at both version (1.6.4), i was able to communicate (send HTTPS requests) with containers in this cluster. After upgrading cluster B, i can send a HTTPS request from B to A.
