pod in kubernetes can't establish the grpc connection

My pod in kubernetes can't establish the grpc connection with other pod. But It can establish the connection after I promote the permissions of POD to privileged. But I can't use privileged pod in production environment.

I add NET_BIND_SERVICE privilege to pod and it can do a little work, which privilege should I add either? I also see the netstat in container, In the normal circumstance, In the abnormal circumstance

Solution

  • I open the grpc log, and found it's the container can't ping another container ipv6 address successfully.
