Recovering from a disaster

Introduction

In the circumstance that a disaster happens, the replicated contents can be recovered by using a RecoveryExecutionJob. Applying it will execute every recovery process set in the RecoveryPlan collection.

Requirements

• Have access to the destination cluster
• Have configured the recovery plan.

Process

1. Pause the RecoveryPlan

Pause the RecoveryPlan using the following path operation:

kubectl patch recoveryplan <recovery_plan_name> -p '{"spec":{"suspend":true}}' --type=merge

2. Identify the RecoveryExecutionPlan

Identify the RecoveryExecutionPlan configured in the previous step.

3. Deploy the RecoveryExecutionJob

Create the recoveryexecutionjob.yaml file with the following content:

apiVersion: dr.astronetes.io/v1alpha1
kind: RecoveryExecutionJob
metadata:
  generateName: <recovery_execution_plan_name>
  namespace: <namespace_name>
spec:
  recoveryExecutionPlanRef:
    name: <recovery_execution_plan_name>
    namespace: <namespace_name>

Deploy the RecoveryExecutionJob:

kubectl apply -f recoveryexecutionjob.yaml
