Execute the docker version command on the host to check the Server API version and Client API version. The two API versions should be the same.

I'm seeing this as well, it appears that --local ignores ignore_docker_version: true

[wenerme]

I use the DOCKER_API_VERSION env var to fix this. But when I reinstall the rke, the problem was solved, 0.3.2

[YaredTaddese]

ctx := context.Background()
cli, err := client.NewClientWithOpts(client.FromEnv)
if err != nil {
    panic(err)
}
cli.NegotiateAPIVersion(ctx)

@wenerme NegotiateAPIVersion function seems like it can negotiate API version and solve this issue. At least, it solved this problem for me.
