Download OpenShift Origin package
Un-tar the package
tar -zvxf openshift-origin-client-tools-v3.11.0–0cbc58b-linux-64bit.tar.gz
Copy ‘oc’ command to ‘/usr/local/bin/’ directory on the system
cd openshift-origin-client-tools-v3.11.0–0cbc58b-linux-64bit
cp oc /usr/local/bin/
Verify ‘oc’ version
oc version
Verify ‘oc’ version Output
root@ubuntu:~/# oc version
oc v3.11.0+0cbc58b
kubernetes v1.11.0+d4cacc0
features: Basic-Auth GSSAPI Kerberos SPNEGO
Add Insecure registry to docker daemon and restart docker service
This step is necessary — OpenShift caches images locally for image re-use purposes.
sudo su -
cat << EOF > /etc/docker/daemon.json
{
“insecure-registries” : [ “172.30.0.0/16” ]
}
EOF
Restart docker service
service docker restart (or) systemctl stop docker ; systemctl start docker
Start OpenShift Cluster
oc cluster up
Start OpenShift Cluster Output
root@ubuntu:~# oc cluster up
