Package client

v1.13.1
Latest Go to latest

The latest major version is .

Published: Feb 8, 2017 | License: Apache-2.0 | Module: github.com/docker/docker

Overview

Package client is a Go client for the Docker Engine API.

The "docker" command uses this package to communicate with the daemon. It can also be used by your own Go applications to do anything the command-line interface does – running containers, pulling images, managing swarms, etc.

For more information about the Engine API, see the documentation: https://docs.docker.com/engine/reference/api/

Usage

You use the library by creating a client object and calling methods on it. The client can be created either from environment variables with NewEnvClient, or configured manually with NewClient.

For example, to list running containers (the equivalent of "docker ps"):

package main

import (
	"context"
	"fmt"

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

func main() {
	cli, err := client.NewEnvClient()
	if err != nil {
		panic(err)
	}

	containers, err := cli.ContainerList(context.Background(), types.ContainerListOptions{})
	if err != nil {
		panic(err)
	}

	for _, container := range containers {
		fmt.Printf("%s %s\n", container.ID[:10], container.Image)
	}
}
