Most examples code snippet are taken from the test cases

Intialize docker client
DockerClient dockerClient = new DockerClientImpl("http://localhost:2375");
Get Docker info:
Info info = dockerClient.infoCmd().exec();
System.out.print(info);
Search Docker repository:
List<SearchItem> dockerSearch = dockerClient.searchImagesCmd("busybox").exec();
System.out.println("Search returned" + dockerSearch.toString());
Create new Docker container, wait for its start and stop it:
ContainerCreateResponse container = dockerClient.createContainerCmd("busybox")
   .withCmd("touch", "/test")
   .exec();

dockerClient.startContainerCmd(container.id).exec();
dockerClient.waitContainerCmd(container.id).exec();
dockerClient.stopContainerCmd(container.id).exec();
Create new Docker container and start it with mount binded volumes
Volume volume1 = new Volume("/opt/webapp1");
Volume volume2 = new Volume("/opt/webapp2");

CreateContainerResponse container = dockerClient.createContainerCmd("busybox")
   .withVolumes(volume1, volume2)
   .withCmd("true")
   .exec();

dockerClient.startContainerCmd(container.getId())
   .withBinds(new Bind("/src/webapp1", volume1, true), new Bind("/src/webapp2", volume2))
   .exec();
Create new Docker container and start it with exposed ports
ExposedPort tcp22 = ExposedPort.tcp(22);
ExposedPort tcp23 = ExposedPort.tcp(23);

CreateContainerResponse container = dockerClient.createContainerCmd("busybox")
   .withCmd("true")
   .withExposedPorts(tcp22, tcp23)
   .exec();

Ports portBindings = new Ports();
portBindings.bind(tcp22, Ports.Binding(11022));
portBindings.bind(tcp23, Ports.Binding(11023));

dockerClient.startContainerCmd(container.getId())
   .withPortBindings(portBindings)
   .exec();
Create two Docker containers and start it with linking
CreateContainerResponse container1 = dockerClient.createContainerCmd("busybox")
   .withCmd("sleep", "9999")
   .withName("container1")
   .exec();

dockerClient.startContainerCmd(container1.getId()).exec();

CreateContainerResponse container2 = dockerClient.createContainerCmd("busybox")
   .withCmd("true")
   .withName("container2")
   .exec();

dockerClient.startContainerCmd(container2.getId())
   .withLinks(new Link("container1", "container1Link"))
   .exec();
Build image from Dockerfile
File baseDir = new File("~/kpelykh/docker/netcat");

InputStream response = dockerClient.buildImageCmd(baseDir).exec();

StringWriter logwriter = new StringWriter();

try {
    LineIterator itr = IOUtils.lineIterator(response, "UTF-8");
    while (itr.hasNext()) {
        String line = itr.next();
        logwriter.write(line);
        LOG.info(line);
    }
} finally {
    IOUtils.closeQuietly(response);
}
