Image registry storage recommendations

  • Take account of the following recommendations for the container image registry:

    • Dell EMC recommends using the Dell EMC Unity 380F All Flash array for image-registry storage.
    • Red Hat does not recommend the Red Hat Enterprise Linux-backed NFS server for image-registry storage, although this is possible for POC implementations.
    • Although POC implementations can use “EmptyDir” for image-registry storage, images pushed to the registry are not saved after a reboot.
    • The OC commands that this deployment guide provides configure an NFS-backed Persistent Volume (PV) that is attached to a Unity 380F All-Flash array for image registry storage.

    For information about configuring image-registry in bare-metal installations, see the Red Hat OpenShift 4.2 Install documentation.

    For information about registry values and configuration, see the Red Hat OpenShift 4.2 Image Registry documentation.
