System requirements

Ensure that these requirements are met before you deploy OpenShift Container Platform accelerator and OpenShift Container Platform with OCS accelerator to your system.

  • IBM Cloud Pak® System V2.3.3.0.

  • (IBM® OS image for Red Hat Linux Systems) 64-Bit, V7.7 (RHEL 7.7 X64), base OS image V3.1.0.0:167, which is available with IBM Cloud Pak System V2.3.3.0 default data.

  • IBM OS Image for Red Hat Enterprise Linux CoreOS V4.4.3 is available with IBM Cloud Pak System V2.3.3.0 BYOL binaries.

  • IBM Cloud Pak System Registry Service that is connected to either an external Red Hat OpenShift Container Platform docker repository or internal Docker Private Registry with available OpenShift Container Platform V4.4.6 images.

    Note: This requirement is applicable only for OpenShift Container Platform 4 - HA and not for OpenShift Container Platform 4 - HA with OCS.

  • Red Hat Satellite Six Service that is connected to an external or internal Red Hat Satellite Server with the following packages for use with the Helper Node:

    • rhel-7-server-rpms
    • rhel-7-server-extras-rpms

  • If you are using an external NFS Server for the OpenShift Image Registry, provide permission for OpenShift to access the NFS directory. For example, if /export/ocp is the exported directory, then run the following commands:

    • Set the file access permission:

      chmod 777 /export/ocp/

    • Add the following to /etc/export:

      /export/ocp *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)

    Note: NFS and external NFS are applicable only for the OpenShift Container Platform 4 - HA topology variant. For OpenShift Container Platform 4 - HA with OCS topology variant, OpenShift Container Storage V4.2.3 is used for storage.
