Using persistent storage

Setup a storage volume for persistent data

Storage

odo lets users manage storage volumes in the cluster. A storage volume is a PVC, which is a way for users to “claim” durable storage (such as a GCE PersistentDisk or an iSCSI volume) without knowing the details of the particular cloud environment. The storage volume can be used to persist data across restarts and rebuilds of the component.

Adding a storage volume

We can add a storage volume to the cluster using odo storage create

  $ odo storage create store --path /data --size 1Gi
   ✓  Added storage store to nodejs-project-ufyy

  Please use `odo push` command to make the storage accessible to the component

The storage volume in the above example has been mounted to the /data path and has a size of 1Gi

Listing storage volumes

We can check the storage volumes currently used by the component using odo storage list

  $ odo storage list
  The component 'nodejs-project-ufyy' has the following storage attached:
  NAME      SIZE     PATH      STATE
  store     1Gi      /data     Not Pushed

Deleting a storage volume

We can delete a storage volume using odo storage delete

  $ odo storage delete store -f
  Deleted storage store from nodejs-project-ufyy

  Please use `odo push` command to delete the storage from the cluster
