The master branch in this fork is pointing at v3.0.6 commit hash and on top of that we have made some adjustments in order to be able to run the library with fasterxml version 2.4.3 in order to overcome a version clash.

Java API client for Docker

The current implementation is based on Jersey 2.x and therefore classpath incompatible with older Jersey 1.x dependent libraries!

• Java min 1.7
• Maven 3

Build and run integration tests as follows:

$ mvn clean install

If you do not have access to a Docker server or just want to execute the build quickly, you can run the build without the integration tests:

$ mvn clean install -DskipITs

By default the docker engine is using local UNIX sockets for communication with the docker CLI so docker-java client also uses UNIX domain sockets to connect to the docker daemon by default. To make the docker daemon listening on a TCP (http/https) port you have to configure it by setting the DOCKER_OPTS environment variable to something like the following:

DOCKER_OPTS="-H tcp://127.0.0.1:2375 -H unix:///var/run/docker.sock"

More details about setting up Docker server can be found in official documentation: http://docs.docker.io/en/latest/use/basics/

To force docker-java to use TCP (http) configure the following (see Configuration for details):

DOCKER_HOST=tcp://127.0.0.1:2375

For secure tls (https) communication:

DOCKER_HOST=tcp://127.0.0.1:2376
DOCKER_TLS_VERIFY=1
DOCKER_CERT_PATH=/Users/marcus/.docker/machine/machines/docker-1.11.2

There are a couple of configuration items, all of which have sensible defaults:

• DOCKER_HOST The Docker Host URL, e.g. tcp://localhost:2376 or unix:///var/run/docker.sock
• DOCKER_TLS_VERIFY enable/disable TLS verification (switch between http and https protocol)
• DOCKER_CERT_PATH Path to the certificates needed for TLS verification
• DOCKER_CONFIG Path for additional docker configuration files (like .dockercfg)
• api.version The API version, e.g. 1.23.
• registry.url Your registry's address.
• registry.username Your registry username (required to push containers).
• registry.password Your registry password.
• registry.email Your registry email.

There are three ways to configure, in descending order of precedence:

In your application, e.g.

DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder()
    .withDockerHost("tcp://my-docker-host.tld:2376")
    .withDockerTlsVerify(true)
    .withDockerCertPath("/home/user/.docker/certs")
    .withDockerConfig("/home/user/.docker")
    .withApiVersion("1.23")
    .withRegistryUrl("https://index.docker.io/v1/")
    .withRegistryUsername("dockeruser")
    .withRegistryPassword("ilovedocker")
    .withRegistryEmail("dockeruser@github.com")
    .build();
DockerClient docker = DockerClientBuilder.getInstance(config).build();

DOCKER_HOST=tcp://localhost:2376
DOCKER_TLS_VERIFY=1
DOCKER_CERT_PATH=/home/user/.docker/certs
DOCKER_CONFIG=/home/user/.docker
api.version=1.23
registry.url=https://index.docker.io/v1/
registry.username=dockeruser
registry.password=ilovedocker
registry.email=dockeruser@github.com

java -DDOCKER_HOST=tcp://localhost:2375 -Dregistry.username=dockeruser pkg.Main

export DOCKER_HOST=tcp://localhost:2376
export DOCKER_TLS_VERIFY=1
export DOCKER_CERT_PATH=/home/user/.docker/certs
export DOCKER_CONFIG=/home/user/.docker

In $HOME/.docker-java.properties

In the class path at /docker-java.properties
