1 - Generic Applications

The following RecoveryPlan synchronize many Kubernetes resources between the source and destination clusters:

Deployments
ConfigMaps
Secrets
Services
CronJobs

Filters

Only the resources with label disaster-recovery=enabled will be synchronized.

2 - Namespaces

This RecoveryPlan synchronize namespaces between the source and destination clusters.

Filters

Only the resources with labels disaster-recovery=enabled will be synchronized. Note that system namespaces that start with either kube- or openshift- will not be replicated even when the labels match.

      filters:
        selector:
          matchLabels:
            disaster-recovery: enabled

3 - Secrets

This RecoveryPlan synchronize the secrets between the source and destination clusters.
