<p>I am currently installing QlikSense on Kubernetes. In order to work with Qlik the Kubernetes Cluster needs to have a readwritemany storage class.</p>

<p>How do I configure a readwritemany storage class in EKS with kubectl?</p>

<p>Amazon AWS supports Elastic File System (EFS) as a highly scalable NFS service basically. By installing their new CSI driver in your EKS cluster, this allows a ReadWriteMany storage class. This should satisfy your requirements. You can read more about installing that <a href="https://docs.aws.amazon.com/eks/latest/userguide/efs-csi.html" rel="nofollow noreferrer">here</a>.</p>

<p>Note however that EFS performance will not be great. It depends on how the software will want to use it. For example, hosting a database on EFS is not recommended and will probably be too slow. However, hosting shared files on EFS with moderate load and no stringent latency requirements can work well enough!</p>

<p>I am the developer behind <a href="https://airkube.io/" rel="nofollow noreferrer">airkube.io</a>, which is a managed EKS hosting that runs on AWS spot instances. We tested and had good luck with <a href="https://openebs.io/" rel="nofollow noreferrer">openebs</a>. This is a good option if you need fairly high performance RWX, you can read more about that option <a href="https://docs.openebs.io/docs/next/rwm.html" rel="nofollow noreferrer">here</a>. The opebebs solution might bring slight complexity though especially if you don't have a dedicated SRE person, or use a managed EKS solution. Another possibly simpler solution, is to use <a href="https://github.com/helm/charts/tree/master/stable/nfs-server-provisioner" rel="nofollow noreferrer">NFS provisioner</a>. This deploys an NFS server and dynamically creates PVs as EKS users deploy PVCs.</p>

<p>Hope that was helpful! Don't hesitate to ping me for more details or hands-on help! Regards</p>
