Installing a two data center deployment on OpenShift

How to deploy a two data center disaster recovery (2DCDR) deployment on OpenShift.

Introduction

Ensure that you understand the concepts of 2DCDR in API Connect. For more information, see Two data center warm-standby deployment on Kubernetes and OpenShift.

Familiarize yourself with the OpenShift installation instructions linked from Deploying on OpenShift and Cloud Pak for Integration.

Note: 2DCDR is not supported on OpenShift where the top-level CR is used. For 2DCDR on OpenShift, you must install API Connect as individual subsystems. See Installing API Connect in a single namespace on OpenShift and Installing API Connect subsystems in different namespaces or environments on OpenShift.

Prerequisites

The prerequisites for a 2DCDR deployment on OpenShift are as follows.

  • The management and portal endpoints must be the same on both data centers.
  • The network latency between data centers must be no more than 80 ms.
  • The management cluster in each data center must use the same encryption secret.
  • The portal cluster in each data center must use the same encryption secret.
  • The ingress-ca certificate must be the same on both data centers.
