Create A DR Basic Configuration

DisasterConfig combines source cluster, target cluster, storage repository, DataSync policy, and ResourceSync policy. Multiple instances can reuse one configuration.

Prerequisites​

  • Source and target clusters are registered and Ready.
  • The storage repository exists and is reachable from both clusters.
  • DataSync and ResourceSync policies already exist. A basic DR configuration references both policy types, so create them first in Create DataSync And ResourceSync Policies.

Console​

Open DR Management / Basic Configuration.

DR basic configuration

Create a configuration with source cluster, target cluster, repository, data sync policy, resource sync policy, sync type, and image rewrite rules.

CRD Example​

apiVersion: testudo.softcdata.com/v1
kind: DisasterConfig
metadata:
  name: prod-a-to-prod-b
spec:
  sourceCluster: prod-a
  targetCluster: prod-b
  storageRepository: minio-dr
  dataSyncPolicy: datasync-5m
  resourceSyncPolicy: resourcesync-5m

The configuration is a template. It does not protect an application until an instance references it.
