I want to invoke service in my kuberetes cluster, so I try to invoke servcie(the backend pod deployment by deplyment) like this:
curl http://soa-illidan-hub-service.dabai-fat.svc.cluster.local:11024it tell me curl: (7) Failed to connect to soa-illidan-hub-service.dabai-fat.svc.cluster.local port 11024: Host is unreachable, and I am ping:
/ # ping soa-illidan-hub-service.dabai-fat.svc.cluster.local
PING soa-illidan-hub-service.dabai-fat.svc.cluster.local (10.254.42.62): 56 data bytes
64 bytes from 10.254.42.62: seq=0 ttl=64 time=0.051 ms
64 bytes from 10.254.42.62: seq=1 ttl=64 time=0.063 ms
64 bytes from 10.254.42.62: seq=2 ttl=64 time=0.057 mswhy the curl tell me host is unreachable? and. I could using endpoint ip to invoke servcie,should I using ip? using servcie ip is a good practice?
Try
wget -qO- http://soa-illidan-hub-service.dabai-fat.svc.cluster.localor try directly to pod ip
wget -qO- POD_IP:PORTI finnally find the reason, the pod's running node kube-proxy stopped. Try to start kube-proxy will fix this, in my centos 7.6 start like this:
systemctl start kube-proxy
