func NewClient

func NewClient(defaultHost string) (dockerClient client.CommonAPIClient, dockerHostInRemote string, err error)

NewClient creates a new docker client. reads the DOCKER_HOST env-var but it may or may not return it as dockerHost.

• For local connection (unix socket and windows named pipe) it returns the DOCKER_HOST directly.
• For ssh connections it reads the DOCKER_HOST from the ssh remote.
• For TCP connections it returns "" so it defaults in the remote (note that one should not be use client.DefaultDockerHost in this situation). This is needed beaus of TCP+tls connections.
