Trying to understand why I'm seeing this output from my kube-proxy logs
W0328 08:00:53.755379 1 server.go:468] Failed to retrieve node info: nodes "ip-172-31-55-175" not found
W0328 08:00:53.755505 1 proxier.go:249] invalid nodeIP, initialize kube-proxy with 127.0.0.1 as nodeIP
The cluster is working just fine, is that indicating an issue with the cluster configuration?
回答1:
Can you please show the output of the command kubectl get node?
Probably the registered name used when kubelet starts is different from the name that kube-proxy is using.
You can force the usage of this very same name starting kube-proxy with the --hostname-override directive, and point to the same name kubelet registered itself.
回答2:
For newcomers start the minions(nodes) services in this order. 1. kubelet 2. kube-proxy 3. docker
Incorrect follow ups can trip up the service registrations.
