Description Jake Hunsaker 2015-07-31 14:12:12 UTC

Description of problem:

During boot, the apiserver process may fail to start as it cannot bind to an IP address, resulting in this error:


 Unable to find suitable network address.error='Unable to select an IP.' . Will try again in 5 seconds. Set the public address directly to avoid this wait.


This looks like a race condition where apiserver is trying to get a network address before the interface is ready. By enabling NetworkManager-wait-online.service, we never see kube-apiserver to fail on boot with this message.

Version-Release number of selected component (if applicable):

atomic 7.1.3-1
kubernetes-0.17.1-4.el7


How reproducible:
Reliably


Steps to Reproduce:
1. Have NM control the NICs on the host
2. Reboot
3.

Actual results:
kube-apiserver will fail to start on boot (even after retrying several times), but can be started manually without issue.

Expected results:
kube-apiserver should start normally on boot with no manual intervention

As of Red Hat Enterprise Linux 7.5, the kubernetes packages shipped in the RHEL Extras channel are deprecated, and Red Hat no longer supports the manual installation and configuration of kubernetes on RHEL. OpenShift Container Platform is Red Hat’s fully supported distribution of Kubernetes.
