Installation Manual - 130 spoke-dr-v7 GitOps catalog storage foundation

The accepted GitOps, catalog, image mirror, and LVMS storage foundation for the spoke-dr-v7 compact hot standby workload cluster.

This chapter records #471 / OP-GF-SPOKEDRV7-7, the GitOps, catalog, mirror, and storage foundation gate for spoke-dr-v7.

The result is a foundation gate, not an ACM import or application-parity start. No spoke-dr-v7 hub import, application overlay, CNPG workload, Open Liberty route, failover drill, or failback change was created here.

Governance

Decision

Bring up the same foundation pieces on spoke-dr-v7 that the active v7 clusters use for platform bootstrap:

• disconnected catalog and image mirror bootstrap;
• OpenShift GitOps operator and openshift-gitops;
• ArgoCD extension RBAC for the foundation app path;
• LVMS for the default storage class lvms-vg1.

This gate is still below full hub import and below full workload parity. The cluster is now ready for the next ACM import gate, but it is not yet imported into a hub cluster.

Live Execution Path

The live path was:

local coordinator -> dl385-2 -> gf-ocp-bootstrap-01

The foundation bootstrap was run from the active openshift-platform-gitops clone on gf-ocp-bootstrap-01 against the spoke kubeconfig.

Live Changes

• Applied the bootstrap namespace scaffold for the spoke foundation.
• Applied the disconnected image mirror resources.
• Applied the operator catalog bootstrap.
• Installed the OpenShift GitOps operator and the openshift-gitops instance.
• Applied the ArgoCD extension RBAC needed by the foundation app path.
• Installed LVMS and established StorageClass/lvms-vg1 as the default storage class.

The first pass exposed a bootstrap ordering issue: ResourceQuota was being applied before the baseline ConfigMap in the bootstrap namespace. That was corrected and the script was rerun successfully.

Validation

• openshift-gitops-operator CSV: openshift-gitops-operator.v1.20.3 succeeded.
• openshift-gitops namespace exists.
• ArgoCD/openshift-gitops exists.
• openshift-lvm-storage namespace exists.
• lvms-operator.v4.20.0 CSV succeeded.
• LVMCluster/lvmcluster is Ready.
• StorageClass/lvms-vg1 exists and is the default storage class.

The foundation checks were read-only; no hub import, app overlay, or route promotion was performed.

Residual Risks

• spoke-dr-v7 is still not ACM-imported into any hub cluster.
• Operator/security parity still needs to be completed in later gates.
• ODF/local storage parity, CNPG replication, Open Liberty standby, failover, failback, and final backup/compliance evidence are still pending.
• The bootstrap script must preserve the baseline ConfigMap before ResourceQuota ordering in the bootstrap namespace.

Next Gate

#472 / OP-GF-SPOKEDRV7-8 will import spoke-dr-v7 into hub-dr-v7 and enable pull GitOps for the standby cluster.
