You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

Docker client library in Go
===========================
[![GoDoc](http://godoc.org/github.com/samalba/dockerclient?status.png)](http://godoc.org/github.com/samalba/dockerclient)
Well maintained docker client library.
# How to use it?
Here is an example showing how to use it:
```go
package main
import (
"github.com/samalba/dockerclient"
"log"
"time"
)
// Callback used to listen to Docker's events
func eventCallback(event *dockerclient.Event, ec chan error, args ...interface{}) {
log.Printf("Received event: %#v\n", *event)
}
func main() {
// Init the client
docker, _ := dockerclient.NewDockerClient("unix:///var/run/docker.sock", nil)
// Get only running containers
containers, err := docker.ListContainers(false, false, "")
if err != nil {
log.Fatal(err)
}
for _, c := range containers {
log.Println(c.Id, c.Names)
}
// Inspect the first container returned
if len(containers) > 0 {
id := containers[0].Id
info, _ := docker.InspectContainer(id)
log.Println(info)
}
// Create a container
containerConfig := &dockerclient.ContainerConfig{
Image: "ubuntu:14.04",
Cmd: []string{"bash"},
AttachStdin: true,
Tty: true}
containerId, err := docker.CreateContainer(containerConfig, "foobar")
if err != nil {
log.Fatal(err)
}
// Start the container
hostConfig := &dockerclient.HostConfig{}
err = docker.StartContainer(containerId, hostConfig)
if err != nil {
log.Fatal(err)
}
// Stop the container (with 5 seconds timeout)
docker.StopContainer(containerId, 5)
// Listen to events
docker.StartMonitorEvents(eventCallback, nil)
// Hold the execution to look at the events coming
time.Sleep(3600 * time.Second)
}
```
