Automatically update the kubernetes-service endpoint. #752

Closed bergmannf closed 5 years ago

bergmannf commented 5 years ago

When a cluster is bootstrapped with multiple kube-apiservers, the kubernetes service contains a list of all of these endpoints.

By default, this list of endpoints will not be updated if one of the apiservers goes down. This can lead to the api becoming unresponsive and breaking it. To have the endpoints automatically keep track of the apiservers that are available the --endpoint-reconciler-type option lease needs to be added.

(The default option for 1.10 master-count only changes the endpoint when the count changes: https://github.com/apprenda/kismatic/issues/987)

Fixes bsc#1098664
