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 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)
	}
}

Full documentation is available on GoDoc.

Documentation

Overview

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

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)
	}
}

Variables

var ErrRedirect = errors.New("unexpected redirect in response")

ErrRedirect is the error returned by checkRedirect when the request is non-GET.

Functions

func CheckRedirect 

func CheckRedirect(req *http.Request, via []*http.Request) error

CheckRedirect specifies the policy for dealing with redirect responses: If the request is non-GET return `ErrRedirect`. Otherwise use the last response.

Go 1.8 changes behavior for HTTP redirects (specifically 301, 307, and 308) in the client . The Docker client (and by extension docker API client) can be made to to send a request like POST /containers//start where what would normally be in the name section of the URL is empty. This triggers an HTTP 301 from the daemon. In go 1.8 this 301 will be converted to a GET request, and ends up getting a 404 from the daemon. This behavior change manifests in the client in that before the 301 was not followed and the client did not generate an error, but now results in a message like Error response from daemon: page not found.

ContainerWait waits until the specified container is in a certain state indicated by the given condition, either "not-running" (default), "next-exit", or "removed".

If this client's API version is before 1.30, condition is ignored and ContainerWait will return immediately with the two channels, as the server will wait as if the condition were "not-running".

If this client's API version is at least 1.30, ContainerWait blocks until the request has been acknowledged by the server (with a response header), then returns two channels on which the caller can wait for the exit status of the container or an error if there was a problem either beginning the wait request or in getting the response. This allows the caller to synchronize ContainerWait with other calls, such as specifying a "next-exit" condition before issuing a ContainerStart request.

Example (WithTimeout) 
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

client, _ := NewEnvClient()
_, errC := client.ContainerWait(ctx, "container_id", "")
if err := <-errC; err != nil {
