Generated largely from the specified config; small parts taken from `docker image inspect`, such as the command line. Renamed some of the yaml keys to match the OCI spec rather than Docker Compose as we decided they are more readable, no more underscores. Add some extra functionality - tmpfs specification - fully general mount specification - no new privileges can be specified now For nostalgic reasons, using engine-api to talk to the docker cli as we only need an old API version, and it is nice and easy to vendor...

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"
"golang.org/x/net/context"
)
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(context.Background(), 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.
Developing
engine-api requires some minimal libraries that you can download running make deps.
To run tests, use the command make test. We use build tags to isolate functions and structures that are only available for testing.
To validate the sources, use the command make validate.
