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 or pushing images, etc.

For example, to list all containers (the equivalent of docker ps --all):

package main

import (
	"context"
	"fmt"

	"github.com/moby/moby/client"
)

func main() {
	// Create a new client with "client.FromEnv" (configuring the client
	// from commonly used environment variables such as DOCKER_HOST and
	// DOCKER_API_VERSION) and set a custom User-Agent.
	//
	// API-version negotiation is enabled by default to allow downgrading
	// the API version when connecting with an older daemon version.
	apiClient, err := client.New(
		client.FromEnv,
		client.WithUserAgent("my-application/1.0.0"),
	)
	if err != nil {
		panic(err)
	}
	defer apiClient.Close()

	// List all containers (both stopped and running).
	result, err := apiClient.ContainerList(context.Background(), client.ContainerListOptions{
		All: true,
	})
	if err != nil {
		panic(err)
	}

	// Print each container's ID, status and the image it was created from.
	fmt.Printf("%s  %-22s  %s\n", "ID", "STATUS", "IMAGE")
	for _, ctr := range result.Items {
		fmt.Printf("%s  %-22s  %s\n", ctr.ID, ctr.Status, ctr.Image)
	}
}
