##### CSI plugin

If you want to create a [persistent volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) on a Bottlerocket host, you will need to use the [EBS CSI Plugin](https://github.com/kubernetes-sigs/aws-ebs-csi-driver).
This is because the default EBS driver relies on file system tools that are not included with Bottlerocket.
A walk-through of creating a storage class using the driver is available [here](https://docs.aws.amazon.com/eks/latest/userguide/ebs-csi.html).

##### conntrack configuration

By default `kube-proxy` will set the `nf_conntrack_max` kernel parameter to a default value that may differ from what Bottlerocket originally sets at boot.
