What

This will migrate some PVCs to Portworx volumes

How

  1. Scale down any applications using the PVCs to be migrated.

  2. Edit migrate.sh - set NAMESPACE for the namespace containing the PVCs, and check the LABEL is acceptable.

  3. Label the PVCs to be migrated to match LABEL in step 2:

kubectl label pvc <pvc> -n <namespace> px/migrate=true
kubectl label pvc --all -n <namespace> px/migrate=true
  1. Run the migration:
sh migrate.sh
  1. Scale up your applications

Example

You can install Ondat (formerly known as StorageOS) and provision a PostgreSQL running on top, and migrate that PostgreSQL to Portworx:

sh install-ondat.sh
kubectl apply -f ondat-postgres.yml
kubectl scale deploy postgres -n postgres --replicas 0
kubectl label pvc postgres-ondat -n postgres px/migrate=true
sh migrate.sh
kubectl scale deploy postgres -n postgres --replicas 1
