Removing a two data center deployment
You can remove your two data center disaster recovery deployment on Kubernetes and OpenShift.
Before you begin
Ensure that you understand the concepts of two data center disaster recovery in API Connect. For more information, see A two data center deployment strategy on Kubernetes and OpenShift.
About this task
If you decide to remove your two data center disaster recovery (DR) deployment, you go from two data centers to one. The active data center remains as the only working system. The passive one loses all data as part of the process.
As part of the installation, you included a
multiSiteHA configuration section in
each data center. For example:
If you want to revert to a single data center topology, or temporarily remove the passive data center from DR, you must remove the multi-site HA CR section from the active data center, and then redeploy the passive data center. If the active data center is offline, you must first change the passive data center to be active, and then remove the multi-site HA CR section from the now active data center.
- Remove the
multiSiteHAsection from the Management and Portal subsystem CRs on the active data center.
- Apply the updated CR files to the subsystems on the active data center, for
kubectl apply -f portal_cr.yaml -n <namespace>
kubectl apply -f management_cr.yaml -n <namespace>
<namespace>is the target installation namespace in the Kubernetes cluster for the active data center.
- You must delete your passive data center. For more information, see Uninstalling API Connect.
