K8s容器部署两个项目（主节点操作）
1、创建yaml文件
master节点上创建todo-list.yaml文件，两个jar包设置了两个副本，vue设置了一个副本，端口号固定配置。
当前文件目录为：/home/docker

创建yaml文件命令为：sudo vim todo-list.yaml

文件内容如下，保存文件方法同上：

apiVersion: apps/v1
kind: Deployment

namespace: default

app: web-todo

2、部署
部署命令同样要在todo-list.yaml文件同级目录下进行。

部署命令：

kubectl create -f todo-list.yaml

查看pod:

kubectl get pods -o wide

如果所有pod都在running状态则表示项目都起好了。

查看deployment和service:

kubectl get deployment

kubectl get svc

查看pod日志：

kubectl logs

删除pod,deployment,service

kubectl delete svc note-k8s

kubectl delete deployment note-k8s

kubectl delete pods

3、查看部署好的页面
浏览器访问：192.168.3.200:30260/DLHYXT/dsmMgr/login

至此，前后端均已部署完成。
常用命令
查看所有运行的进程

docker ps -a

停止进程
docker stop id

删除承载进程的容器

docker rm id

删除镜像

docker rmi <镜像ID>

我们生成的镜像一般都是打过标签的，会出现同一个镜像ID对应两个镜像的情况，这时候删除命令为：

docker rmi [REPOSITORY]:[TAG]
