• Verifying an OpenShift 3.5 Installation

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

On Masters

On each master node, run as root:

oc get nodes --show-labels

Output example:

Web Console

At this point the web console should be exposed on the external interface.

https://master.openshift35.external/

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

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

HAProxy Load Balancer Adjustments

Configure the load balancer HAProxy to log in/var/log/haproxy.log. The procedure is described here:

HAProxy Logging Configuration

Verify etcd

• etcd Cluster Health
• etcd Member List

Exported Filesystems

• Clarify the NFS directory/volume and update hosts/hosts-min

On the support node run exportfs and make sure the following filesystems are exported:

/storage/registry
/storage/metrics
/storage/logging
/exports/logging-es-ops

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.
