Limitations

Deploying Kubernetes on Localhost (LXD) provider.

There are some unknown issues when attempting to deploy Kubernetes on LXD with a storage of ZFS or btrfs. The most common error is "Waiting for kube-system pods to start".

Until a solution is found, please only use the dir storage backend when configuring LXD.
