Chapter 1. Overview of deploying in external mode

Red Hat OpenShift Container Storage can use an externally hosted Red Hat Ceph Storage (RHCS) cluster as the storage provider. This deployment type is supported for bare metal and user-provisioned VMware environments. See Planning your deployment for more information.

For instructions regarding how to install a RHCS 4 cluster, see Installation guide.

Follow these steps to deploy OpenShift Container Storage in external mode:

  1. If you use Red Hat Enterprise Linux hosts, Enable file system access for containers.

    Skip this step if you use Red Hat Enterprise Linux CoreOS (RHCOS) hosts.

  2. Install the OpenShift Container Storage Operator.
  3. Create the OpenShift Container Storage Cluster Service.
