OpenShift APIs for Data Protection (OADP) Demo

This repo contains supporting files for OADP demo for this blog entry: Back up Kubernetes persistent volumes using OADP

Deploy sample application: WordPress

We need to deploy a Kubernetes application that uses persistent volumes. We will use WordPress, which uses the MySQL database. The instructions were based on this link.

1. Download the MySQL deployment configuration file:

   curl -LO \
   https://raw.githubusercontent.com/yortch/oadp/main/mysql-deployment.yaml
   

2. Download the WordPress configuration file:

   curl -LO \
   https://raw.githubusercontent.com/yortch/oadp/main/wordpress-deployment.yaml
   

3. Export PASSWORD as an environment variable:

   PASSWORD=<YOUR_PASSWORD>
   

4. Generate the following kustomization.yaml file:

   cat <<EOF >./kustomization.yaml
   secretGenerator:
   - name: mysql-pass
   literals:
   - password=${PASSWORD}
   resources:
   - mysql-deployment.yaml
   - wordpress-deployment.yaml
   EOF
   

5. Create a new application project:

   oc new-project wordpress
   

6. Apply the kustomization.yaml file:

   oc apply -n wordpress -k ./
   

7. Next, expose the WordPress service:

   oc expose service wordpress -n wordpress
   

8. Print the service URL and navigate to it from a browser.

   echo http://$(oc get route -n wordpress -o jsonpath='{.items[0].spec.host}')
   

9. Proceed with the initial WordPress setup so that it is included in the backup.
