Stateless Application Backup/Restore - Nginx

Using an AWS s3 Bucket

Prerequisites

  • OADP operator, a credentials secret, and a DataProtectionApplication (DPA) CR are all created. Follow these steps for installation instructions.

    • Make sure your DPA CR is similar to below in the install step.

  • Information on backupLocations spec can be found here.

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: dpa-sample
spec:
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - aws
    nodeAgent:
      enable: true
      uploaderType: restic
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: my-bucket
          prefix: my-prefix
        config:
          region: us-east-1
          profile: "default"
        credential:
          name: cloud-credentials
          key: cloud

Create the Nginx deployment:

oc create -f docs/examples/manifests/nginx/nginx-deployment.yaml

This will create the following resources:

  • Namespace
  • Deployment
  • Service
  • Route

Verify Nginx deployment resources:

oc get all -n nginx-example

Should look similar to this:

$ oc get all -n nginx-example

Create application backup

oc create -f docs/examples/manifests/nginx/nginx-stateless-backup.yaml

Verify backup is completed

oc get backup -n openshift-adp nginx-stateless -o jsonpath='{.status.phase}'

should result in Completed

Delete the Nginx application

Once we have ensured the backup is completed, we want to test the restore process. First, delete the nginx-example project:

oc delete namespace nginx-example

Create the restore for the application

oc create -f docs/examples/manifests/nginx/nginx-stateless-restore.yaml

Ensure the restore has completed

oc get restore -n openshift-adp nginx-stateless -o jsonpath='{.status.phase}'

Should result in Completed

Verify resources have been recreated in the restore process

oc get all -n nginx-example

Should look similar to this:
