GCP MySQL with private IP not reachable from GKE

Question

I have a mysql instance running with private IP enabled. When I try to connect using mysql-client from GKE container I get connection timeouts.

But mysql-client from VM instances is able to reach the server.

I verified that MySQL, VM instance, GKE all running with default network in same zone.

Answer 1

原来应该在GKE上启用Alias IP，以使用私有IP访问SQL。
