<p>I'm trying to connect my k8s cluster to my ceph cluster with  this manual:
<a href="https://akomljen.com/using-existing-ceph-cluster-for-kubernetes-persistent-storage/" rel="nofollow noreferrer">https://akomljen.com/using-existing-ceph-cluster-for-kubernetes-persistent-storage/</a></p>

<p>I want to deploy rbd-provision pods into kube-system namespace like this <a href="https://paste.ee/p/C1pB4" rel="nofollow noreferrer">https://paste.ee/p/C1pB4</a> </p>

<p>After deploying pvc I get errors because my pvc is in default namespace. Can I do with that anything? I read docs and if I'm right I can't use ServiceAccount with 2 ns, or can?</p>

<p>Service accounts can be granted permissions in another namespace. </p>

<p>For example, within the namespace "acme", grant the permissions in the <code>view</code> <code>ClusterRole</code> to the service account in the namespace "acme" named "myapp" :</p>

<pre><code>kubectl create rolebinding myapp-view-binding \
  --clusterrole=view --serviceaccount=acme:myapp \
  --namespace=acme
</code></pre>
