将 SpringCloud 微服务项目部署至 K8S 平台，以下步骤均在 k8s 的 master1 节点操作

（1）安装 openjdk 和 maven

在 k8s 的 master1 节点操作:

yum install java-1.8.0-openjdk maven-3.0.5* -y

 （2）上传微服务源码包到 k8s 的 master 节点

unzip microservic-test.zip
cd microservic-test

[root@master microservic-test]# ls
basic-common  eureka-service   k8s      lombok.config  pom.xml         product-service  stock-service
db            gateway-service  LICENSE  order-service  portal-service  README.md

（3）在 k8s 的 master1 节点操作

1）修改库存数据库

[root@master ~]# cd microservic-test
[root@master microservic-test]# cd stock-service/
[root@master stock-service]# ls
pom.xml  stock-service-api  stock-service-biz
[root@master stock-service]# cd stock-service-biz/
[root@master stock-service-biz]# ls
Dockerfile  pom.xml  src  target
[root@master stock-service-biz]# cd src/
[root@master src]# ls
main
[root@master src]# cd main/
[root@master main]# ls
java  resources
[root@master main]# cd resources/
[root@master resources]# ls
application-dev.yml  application-fat.yml  application.yml
[root@master resources]# vim application-fat.yml 
spring:
  datasource:
url: jdbc:mysql://192.168.0.12:3306/tb_stock?characterEncoding=utf-8

[root@master microservic-test]# cd product-service/

就是将order,product，stock数据库的地址都修改为自己的数据库地址。

（4)通过 Maven 编译、构建、打包源代码

在 k8s 的 master1 节点操作

修改源代码之后回到/root/microservic-test 目录下执行如下命令：

[root@master microservic-test]# mvn clean package -D maven.test.skip=true
