commandconn

Overview ¶

Package commandconn provides a net.Conn implementation that can be used for proxying (or emulating) stream via a custom command.

For example, to provide an http.Client that can connect to a Docker daemon running in a Docker container ("DIND"):

httpClient := &http.Client{
	Transport: &http.Transport{
		DialContext: func(ctx context.Context, _network, _addr string) (net.Conn, error) {
			return commandconn.New(ctx, "docker", "exec", "-it", containerID, "docker", "system", "dial-stdio")
		},
	},
}
