Red Hat Openshift Container Platform 3.9
Showing errors
cni.go:171] Unable to update cni config: No networks found in /etc/cni/net.d There are no files in that directory as opposed to a working node which has a file named 80-openshift-network.conf kubelet_node_status.go:106] Unable to register node “ip-10-200-30-40.openshift-example.com” with API server: nodes “ip-10-200-30-40.openshift-example.com” is forbidden: node “ip-10-200-30-40.openshift-example.com” cannot modify node “ip-10-200-30-40.openshift-example.com”
This error is what happens when the host cannot resolve itself in DNS.
Root Cause
On this issue the VPC’s “DHCP Options Set”, had the value of domain-name = openshift-example.com instead of domain-name = openshift.example.com (notice the dash vs the period before the word ‘example’)
