I have a pod in Redhat Openshift running Tomcat and inside Tomcat I have Ozone Widget Framework, my site hosted in Tomcat. I have executed the oc command to use my existing configuration so that my pod won't disappear and lose my session and data. I ran

oc cluster up --host-data-dir=/path_to_data/openshiftdata --use-existing-config

But after making changes within OWF, when I take down the cluster and bring it back up my pod lives on, but my OWF instance is reverted back to it's default state.

How do I get Openshift to let Tomcat retain OWF's state?

You need to use a Persitent Volume.

Your /path_to_data/openshiftdata is probably on a disk that belongs to the pod and is being destroyed each time.

  • My path_to_data is set to a folder in my home directory, I don't think it can be owned by the pod. My Openshift project and it's pod were being destroyed when I shut down Openshift until I started using the switches above. – DemiSheep Mar 20 '18 at 1:12
