Introduction

Engine-api is a set of Go libraries to implement client and server components compatible with the Docker engine. The code was extracted from the Docker engine and contributed back as an external library.

Components

Client

The client package implements a fully featured http client to interact with the Docker engine. It's modeled after the requirements of the Docker engine CLI, but it can also serve other purposes.

Usage

You can use this client package in your applications by creating a new client object. Then use that object to execute operations against the remote server. Follow the example below to see how to list all the containers running in a Docker engine host:

package main

import (
	"fmt"
	"github.com/docker/engine-api/client"
	"github.com/docker/engine-api/types"
)

func main() {
	defaultHeaders := map[string]string{"User-Agent": "engine-api-cli-1.0"}
	cli, err := client.NewClient("unix:///var/run/docker.sock", "v1.22", nil, defaultHeaders)
	if err != nil {
		panic(err)
	}

	options := types.ContainerListOptions{All: true}
	containers, err := cli.ContainerList(options)
	if err != nil {
		panic(err)
	}

	for _, c := range containers {
		fmt.Println(c.ID)
	}
}
Types

The types package includes all typed structures that client and server serialize to execute operations.

Server

The server package includes API endpoints that applications compatible with the Docker engine API can reuse. It also provides useful middlewares and helpers to handle http requests.

This package is still pending to be extracted from the Docker engine.

Overview

Package engineapi provides libraries to implement client and server components compatible with the Docker engine.

The client package in github.com/docker/engine-api/client implements all necessary requests to implement the official Docker engine cli.

Create a new client, then use it to send and receive messages to the Docker engine API:

defaultHeaders := map[string]string{"User-Agent": "engine-api-cli-1.0"}
cli, err := client.NewClient("unix:///var/run/docker.sock", "v1.22", nil, defaultHeaders)

Other programs, like Docker Machine, can set the default Docker engine environment for you. There is a shortcut to use its variables to configure the client:

cli, err := client.NewEnvClient()

All request arguments are defined as typed structures in the types package. For instance, this is how to get all containers running in the host:

options := types.ContainerListOptions{All: true}
containers, err := cli.ContainerList(options)
