DNS and Storage Requirements

All of the services ingresses require DNS names to be pre-populated to get access to.

• Openshift: the GlusterFS storage should be pre-populated manually.
• NFS (for premise deployments) - should be pre-populated manually.
• GKE - just works out of the box, no further interaction required.
• AWS - dynamic storage provisioning works out of the box.
• No storage - just set the PERSISTENT_STORAGE to false variable in your environment file.
