## WIP not yet integrated into KubeZero
### EFS CSI
To deploy the EFS CSI driver the backing EFS filesystem needs to be in place ahead of time. This is easy to do by enabling the EFS functionality in the worker CloudBender stack.
- retrieve the EFS: `cloudbender outputs config/kube-control-worker.yaml` and look for *EfsFileSystemId*
- update values.yaml in the `aws-efs-csi` artifact folder as well as the efs_pv.yaml
- execute `deploy.sh`
### Istio
Istio is currently pinned to version 1.4.X as this is the last version supporting installation via helm charts.
Until Istio is integrated into KubeZero as well as upgraded to 1.6 we have to install manually.
