docker-java

docker-java 是 Docker的 Java 版本API Docker

当前的实现基于 Jersey 2.x 因此 classpath 不兼容老版本的 Jersey 1.x !

版本支持

Supports a subset of the Docker Remote API v1.37, Docker Server version since 1.12.6

配置Docker环境

系统的可配置项及默认值如下:

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:

编程方式配置:

DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder()

.withDockerHost("tcp://my-docker-host.tld:2376")

.withDockerTlsVerify(true)

.withDockerCertPath("/home/user/.docker/certs")

.withDockerConfig("/home/user/.docker")

.withApiVersion("1.30") // optional

.withRegistryUrl("https://index.docker.io/v1/")

.withRegistryUsername("dockeruser")

.withRegistryPassword("ilovedocker")

.withRegistryEmail("dockeruser@github.com")

.build();

DockerClient docker = DockerClientBuilder.getInstance(config).build();

通过Properties (docker-java.properties)

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

通过System Properties:

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

通过 Environment

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

测试

我们来简单测试下：

DockerClient dockerClient = createClient();

// docker info

Info info = dockerClient.infoCmd().exec();

System.out.print(info);

// 搜索镜像

List dockerSearch = dockerClient.searchImagesCmd("busybox").exec();

System.out.println("Search returned" + dockerSearch.toString());

// pull

dockerClient.pullImageCmd("busybox:latest").exec(new ResultCallback() {

public void onStart(Closeable closeable) {

}

public void onNext(PullResponseItem object) {

System.out.println(object.getStatus());

}

public void onError(Throwable throwable) {

throwable.printStackTrace();

}

public void onComplete() {

System.out.println("pull finished");

}

public void close() throws IOException {

}

});

// 创建container 并测试

// create

CreateContainerResponse container = dockerClient.createContainerCmd("busybox")

.withCmd("/bin/bash")

.exec();

// start

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

dockerClient.stopContainerCmd(container.getId()).exec();

dockerClient.removeContainerCmd(container.getId()).exec();

EventsResultCallback callback = new EventsResultCallback() {

@Override

public void onNext(Event event) {

System.out.println("Event: " + event);

super.onNext(event);

}

};

dockerClient.eventsCmd().exec(callback).awaitCompletion().close();
