Starting elasticsearch in kubernetes

I am trying to start elasticsearch in kubernetes. I have used the quick starting guide therefore my manifest file looks like this:

    kind: Elasticsearch
    metadata:
      name: elasticsearch
      namespace: rcc
    spec:
      version: 7.11.0
      nodeSets:
      - name: default
        count: 1
        config:
          node.store.allow_mmap: false

However it does not start because it is waiting for a PVC but I didn't created any PVC for it.
