Hi, we’ve been investigating Kubernetes running on Rancher but it seems network connections to the apiserver are very unstable. We see sporadic timeouts from services like helm/tiller and kubectl. In the logs we see a number of connection resets e.g.:
2017/11/03 01:30:45 uninstall: Failed deletion of “redacted”: Delete https://172.19.0.1:443/api/v1/persistentvolumes/redacted: read tcp 172.18.176.125:60152->172.19.0.1:443: read: connection reset by peer
E1103 02:34:53.839563 5 leaderelection.go:253] error retrieving resource lock nginx-ingress/ingress-controller-leader-nginx: Get https://172.19.0.1:443/api/v1/namespaces/nginx-ingress/configmaps/ingress-controller-leader-nginx: read tcp 172.18.8.82:39570->172.19.0.1:443: read: connection reset by peer
Does anyone have any ideas on troubleshooting this? We’re using the ipsec network plugin.
