sudo systemctl daemon-reload
sudo systemctl restart docker
  • Download and install OpenShift
tar xvfz openshift-origin-client-tools-v3.9.0-191fece-linux-64bit.tar.gz
sudo mv openshift-origin-client-tools-v3.9.0-191fece-linux-64bit/oc /usr/local/bin
rm openshift-origin-client-tools-v3.9.0-191fece-linux-64bit.tar.gz
rm –rf openshift-origin-client-tools-v3.9.0-191fece-linux-64bit
oc version
