OpenShift Installation Validation
External
Internal
Connect to the Support Node
As "ansible":
On All Nodes
OpenShift Packages
ansible nodes -m shell -a "yum list installed | grep openshift"
The desired OpenShift version must be installed.
OpenShift Version
ansible nodes -m shell -a "/usr/bin/openshift version" master1.local | SUCCESS | ... openshift v3.5.5.26 kubernetes v1.5.2+43a9be4 etcd 3.1.0
Exported Filesystems
On the support node run exportfs and make sure the following filesystems are exported:
exportfs
/nfs 192.168.122.0/255.255.255.0 /nfs/registry <world> /nfs/metrics <world> /nfs/logging <world> /nfs/logging-es-ops <world> /nfs/etcd <world>
On Masters
On each master node, run as root:
oc get nodes --show-labels
Output example:

Verify etcd
On nodes that run etcd, as root:
etcdctl cluster-health etcdctl member list
Note that etcdctl2 should be used on OCP 3.7 onward.
Docker Logs
Log into a few nodes and take a look at the docker logs:
journalctl -f -u docker
Docker Startup Paramenters
From the support/installation server, execute as "ansible":
ansible nodes -m shell -a "ps -ef | grep dockerd | grep -v grep"
Make sure "--selinux-enabled" and "--insecure-registry 172.30.0.0/16" are present.
--insecure-registry does not seem to propagate, update /etc/sysconfig/docker manually on all docker nodes with '--insecure-registry 172.30.0.0/16'.
Master Web Console
At this point the web console should be exposed on the external interface.
Use the administrative user defined as part of your "identity provider" declaration.

Per-project Validation
Logging Installation Validation
Must be performed after logging installation and post-install configuration:
Metrics Installation Validation
Must be performed after metrics installation and post-install configuration:
