You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: docker_socket.go
    path of file: ./repos/zeebe/clients/go/vendor/github.com/testcontainers/testcontainers-go/internal/core
    
    the code of the file until where you have to start completion: package core

import (
	"net/url"
	"strings"

	"github.com/docker/docker/client"
)

// DockerSocketSchema is the unix schema.
var DockerSocketSchema = "unix://"

// DockerSocketPath is the path to the docker socket under unix systems.
var DockerSocketPath = "/var/run/docker.sock"

// DockerSocketPathWithSchema is the path to the docker socket under unix systems with the unix schema.
var DockerSocketPathWithSchema = DockerSocketSchema + DockerSocketPath

// TCPSchema is the tcp schema.
var TCPSchema = "tcp://"

// WindowsDockerSocketPath is the path to the docker socket under windows systems.
var WindowsDockerSocketPath =
    
func init() {
	const DefaultDockerHost = client.DefaultDockerHost

	u, err := url.Parse(DefaultDockerHost)
	if err != nil {
		// unsupported default host specified by the docker client package,
		// so revert to the default unix docker socket path
		return
	}

	switch u.Scheme {
	case "unix", "npipe":
		DockerSocketSchema = u.Scheme + "://"
		DockerSocketPath = u.Path
		if !strings.HasPrefix(DockerSocketPath, "/") {
			// seeing as the code in this module depends on DockerSocketPath having
			// a slash (`/`) prefix, we add it here if it is missing.
			// for the known environments, we do not foresee how the socket-path
			// should miss the slash, however this extra if-condition is worth to
			// save future pain from innocent users.
			DockerSocketPath = "/" + DockerSocketPath
		}
		DockerSocketPathWithSchema = DockerSocketSchema + DockerSocketPath
	}
