Kubernetes1.14.1的开发指南

本篇内容主要讲解“Kubernetes1.14.1的开发指南”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Kubernetes1.14.1的开发指南”吧!

从yaml生成对象

Yaml yaml = new Yaml();
ExtensionsV1beta1Deployment body = yaml.loadAs(new FileReader("deployment.yaml"), ExtensionsV1beta1Deployment.class);
ExtensionsV1beta1Api api = new ExtensionsV1beta1Api();
api.createNamespacedDeployment("default", body, "");

import io.kubernetes.client.ApiClient
import io.kubernetes.client.apis.CoreV1Api
import io.kubernetes.client.util.Config

  def setKubeApiClient() throws IOException, ApiException {
    StringReader reader = new StringReader(this.kubeConfig)
    ApiClient apiClient = Config.fromConfig(reader)
    Configuration.setDefaultApiClient(apiClient)
    this.api = new CoreV1Api()
  }

Where kubeConfig is a yaml.

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

import org.yaml.snakeyaml.Yaml;

import io.kubernetes.client.ApiException;
import io.kubernetes.client.models.ExtensionsV1beta1Deployment;
import io.kubernetes.client.models.V1Namespace;
import io.kubernetes.client.models.V1Service;

public class Solution {

	private static final String yaml_file = "/home/karthik/Desktop/cloud/java/kubernetes/1.yaml";
	static Map<String,Object> objMap = new HashMap<>();
	static Yaml yaml = new Yaml();
	static {
		objMap.put("Deployment", ExtensionsV1beta1Deployment.class);
		objMap.put("Namespace",V1Namespace.class);
		objMap.put("Service", V1Service.class);
                //fill the hashmap
	}
	
	public static void main(String[] args) throws FileNotFoundException, ApiException {
		FileReader fr =new FileReader(yaml_file);
	    InputStream input = new FileInputStream(new File(yaml_file));
		Map map = (Map) yaml.load(input);
		ExtensionsV1beta1Deployment body = (ExtensionsV1beta1Deployment) convertyamlToObject(fr, (String) map.get("kind"));
		ExtensionsV1beta1Api api = new ExtensionsV1beta1Api();
		System.out.println(body);
	}
	
	public static Object convertyamlToObject(FileReader fr, String kind) {
		return yaml.loadAs(fr, (Class<Object>) objMap.get(kind));
	}
}
