使用的k8s client包:

<dependency>
	<groupId>io.fabric8</groupId>
	<artifactId>kubernetes-client</artifactId>
	<version>2.6.1</version>
	<exclusions>
		<exclusion>
			<artifactId>slf4j-api</artifactId>
			<groupId>org.slf4j</groupId>
		</exclusion>
	</exclusions>
</dependency>
<dependency>
	<groupId>io.fabric8</groupId>
	<artifactId>kubernetes-model</artifactId>
	<version>1.1.4</version>
</dependency>
<dependency>
	<groupId>io.fabric8</groupId>
	<artifactId>kubernetes-api</artifactId>
	<version>2.3.5</version>
	<exclusions>
		<exclusion>
			<artifactId>slf4j-api</artifactId>
			<groupId>org.slf4j</groupId>
		</exclusion>
	</exclusions>
</dependency>

  

使用方式k8sApiUrl为k8s apiserver地址:

Config config = new ConfigBuilder().withMasterUrl(k8sApiUrl).build();
DefaultKubernetesClient kubernetesClient = new DefaultKubernetesClient(config);

  

然后可以通过kubernetesClent进行RC创建、删除、scale;service创建删除等等操作,另外就是传入执行命令:

// 创建RC
kubernetesClient.replicationControllers().inNamespace(namespace).createOrReplace(rc);

//扩缩容
kubernetesClient.replicationControllers().inNamespace(namespace).withName(
                rcName).scale(replicas);

// POD执行命令
kubernetesClient.pods().withName(podName).exec("command1","command2");

更多方法自行挖掘,比如RC、POD、Endpoints 监听......
