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