As the final step, add the `dockerless` tags to all files in the dockershim. Using `-tags=dockerless` in `go build`, we can compile kubelet without the dockershim. Once cadvisor no longer depends on `docker/docker`, compiling with `-tags=dockerless` should be sufficient to compile the Kubelet w/o a dependency on `docker/docker`.
