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:

NAME                           STATUS                     AGE       LABELS

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.

https://master.openshift.novaordis.io/

Use the administrative user defined as part of your "identity provider" declaration.

Router Status

oc -n default get deploymentconfigs/router
NAME      REVISION   DESIRED   CURRENT   TRIGGERED BY
router    5          1         1         config

The values in the DESIRED and CURRENT columns should match the number of nodes hosts.
