Cannot create block storage volume

I’m following:

https://docs.digitalocean.com/products/kubernetes/how-to/add-volumes/

But both the pod I create and the pvc remain in pending state.

When I run kubectl describe pod elasticsearch-basic-0 (I’m following https://www.digitalocean.com/community/tutorials/how-to-set-up-an-elasticsearch-fluentd-and-kibana-efk-logging-stack-on-kubernetes tutorial as well to add elastic search) I get:

According to the first tutorial DO should automatically create a block storage volume but this does not seem to be happening. Am I missing something? Thanks.
