前一篇提到了docker-java，这里介绍另一个docker client 库，Docker Client

版本兼容

兼容17.03.1~ce - 17.12.1~ce (点 [here][1]查看).

下载jar包

点击 [via Maven][maven-search]搜索和下载最新的jar包.

pom.xml配置如下：

<dependency>

  <groupId>com.spotify</groupId>

  <artifactId>docker-client</artifactId>

  <version>LATEST-VERSION</version>

</dependency>

当前最新的是8.15.0

<dependency>

	<groupId>com.spotify</groupId>

	<artifactId>docker-client</artifactId>

	<version>8.15.0</version>

</dependency>

使用举例

// Create a client based on DOCKER_HOST and DOCKER_CERT_PATH env vars

final DockerClient docker = DefaultDockerClient.fromEnv().build();

// Pull an image

docker.pull("busybox");

// Bind container ports to host ports

final String[] ports = {"80", "22"};

final Map<String, List<PortBinding>> portBindings = new HashMap<>();

for (String port : ports) {

    List<PortBinding> hostPorts = new ArrayList<>();

    hostPorts.add(PortBinding.of("0.0.0.0", port));

    portBindings.put(port, hostPorts);

}

// Bind container port 443 to an automatically allocated available host port.

List<PortBinding> randomPort = new ArrayList<>();

randomPort.add(PortBinding.randomPort("0.0.0.0"));

portBindings.put("443", randomPort);

final HostConfig hostConfig = HostConfig.builder().portBindings(portBindings).build();

// Create container with exposed ports

final ContainerConfig containerConfig = ContainerConfig.builder()

    .hostConfig(hostConfig)

    .image("busybox").exposedPorts(ports)

    .cmd("sh", "-c", "while :; do sleep 1; done")

    .build();

final ContainerCreation creation = docker.createContainer(containerConfig);

final String id = creation.id();

// Inspect container

final ContainerInfo info = docker.inspectContainer(id);

// Start container

docker.startContainer(id);

// Exec command inside running container with attached STDOUT and STDERR

final String[] command = {"sh", "-c", "ls"};

final ExecCreation execCreation = docker.execCreate(

    id, command, DockerClient.ExecCreateParam.attachStdout(),

    DockerClient.ExecCreateParam.attachStderr());

final LogStream output = docker.execStart(execCreation.id());

final String execOutput = output.readFully();

// Kill container

docker.killContainer(id);

// Remove container

docker.removeContainer(id);

// Close the docker client

docker.close();
