这个报错是在用docker启动autok3s的时候报的错误。已经解决，解决方法：docker run 的时候将~/.k3d目录挂载进容器

[orangedeng]

Seems like it is a k3d limitation. You will encounter the same issue with k3d cli to generate k3s cluster.

[piaobeizu]

no, i generate a k3s cluster successfully with k3d cli.

[orangedeng]

If you are running docker as remote server via setting DOCKER_HOST environment variable, you will encounter the same problem. This is the problem that k3d needs to mount the resource limit file into k3s container which requires the k3d and the docker server are in the same host.

[piaobeizu]

yes, my k3d and docker server are in the same host.

Updated docs for K3d provider. If running AutoK3s with docker and want to use K3d provider, please mount the .k3d directory to the docker container. Please feel free to reopen the issue if there's still have any problems here. Thanks.
