环境：（docker ,k8s集群），继续上次docker 启动的java程序的镜像为例(https://www.cnblogs.com/levcon/p/12442662.html)

将制作的镜像推送到docker的私有仓库

docker tag demo-img:latest localhost:5000/demo-img:1.0

docker push localhost:5000/demo-img:1.0

k8s部署该镜像

k8s创建命名空间及secret

创建命名空间cl-test，这里名字根据自己的命名规范自己定义，我这是测试用的

kubectl create namespace cl-test

创建完ns后，我们要给这个ns创建secret

kubectl create secret docker-registry regcred --docker-server=your resroty ip:5000 --docker-username=root --docker-password=xxxx@ --docker-email=xxxx@163.com -n cl-test

控制台返回“secret/regcred created”表示创建成功

创建demo服务的yaml文件，我们service和deployment放在一个yaml文件中
