Obtain the Multi-Cluster Manager deployment images

Download the IBM Storage Ceph Multi-Cluster Manager deployment images from IBM Cloud Container Registry (ICR).

Before you begin

Before you begin, make sure that you have the following prerequisites in place:

A host with internet access.
The ORAS (OCI Registry As Storage) command-line utility installed.

Note: ORAS is a command-line utility that enables storage and retrieval of artifacts from OCI-compliant registries. Multi-Cluster Manager deployment images are distributed as OCI artifacts and require the ORAS CLI for download. For more information, see the ORAS website.
Valid IBM Customer Portal credentials with access to IBM Cloud Container Registry (cp.icr.io).
Sufficient disk space to store the downloaded deployment images.
A valid Red Hat Enterprise Linux (RHEL) subscription.
