一、案例

  1.1 自主式创建service关联上方的pod

资源名称	my-nginx-kkk
命名空间	my-kkk
容器镜像	nginx:1.21
容器端口	80
标签	njzb:my-kkk

1.1.1 创建一个demo文件夹

  1.1.2 创建并获取模版文件

  1.1.3 查看服务并编写yaml文件

  1.1.4 编写yaml文件并部署，查看服务是否运行成功

apiVersion: v1
kind: Namespace
metadata:name: my-kkk
---
apiVersion: v1
kind: Pod
metadata:labels:njzb: my-kkkname: my-nginx-kkknamespace: my-kkk
spec:containers:- image: nginx:1.21name: my-nginx-kkkports:- containerPort: 80restartPolicy: Always

apiVersion: v1

spec:ports:- nodePort: 31111  ###节点端口号port: 80         ###服务暴露端口protocol: TCP    ###通信协议targetPort: 80   ###要转发到的容器端口selector:njzb: my-kkk     ###该服务所选择的后端podtype: NodePort

修改yaml文件

apiVersion: v1
kind: Namespace
metadata:name: my-kkk
---
apiVersion: v1
kind: Pod
metadata:labels:njzb: my-kkkname: my-nginx-kkknamespace: my-kkk
spec:containers:- image: nginx:1.21name: my-nginx-kkkports:- containerPort: 80restartPolicy: Always

查看所有内容，进入到pod内，输入内容，退出后检测是否有内容 

  1.2 部署redis

  1.2.1 编写redis配置文件 

apiVersion: apps/v1
kind: Deployment
metadata:name: redis-dpmlabels:app: redis
spec:               ###资源所需参数replicas: 1selector:matchLabels:app: redis   ###只会与标签app：redis的pod关联template:          ###业务模板，如果有多个副本，所有副本属性会按照模板进行匹配metadata:labels:app: redisspec:           ###资源所需参数containers:- name: redisimage: redis:latestports:- containerPort: 6379

apiVersion: v1
kind: Service
metadata:name: redis-dbmlabels:app: redis
spec:selector:app: redisports:- nodePort: 32379port: 6379protocol: TCPtargetPort: 6379type: NodePort

  1.2.2 运行redis配置文件

  1.2.3 查看是否有服务和pod端口

  1.3 部署myapp

  1.3.1 编写myapp配置文件

apiVersion: apps/v1
kind: Deployment
metadata:name: myapp-kknamespace: defaultlabels:app: myapp
spec:replicas: 1selector:matchLabels:app: myapptemplate:metadata:labels:app: myappspec:containers:- name: myappimage: soscscs/myapp:v1ports:- containerPort: 80

  1.3.2 运行服务并查看default下的pod是否运行成功

  1.4 部署mysql

  1.4.1 编写mysql配置文件

apiVersion: v1
kind: Namespace
metadata:name: mysql-server
---
apiVersion: apps/v1
kind: Deployment
metadata:labels:app: mysql-01name: mysql-01namespace: mysql-server
spec:                     replicas: 1              selector:               matchLabels:         app: mysql-01        template:                metadata:             labels:           app: mysql-01spec:              containers:- image: mysql:latest         name: mysql                ports:                    - containerPort: 3306    env:                    - name: MYSQL_ROOT_PASSWORD  value: "123123"  volumeMounts:- name: mysql-datamountPath: /var/lib/mysqlvolumes:- name: mysql-dataemptyDir: {}

metadata:name: mysql-servicenamespace: mysql-serverlabels:app: mysql-01
spec:type: NodePortports:- port: 3306targetPort: 3306selector:app: mysql-01

   1.4.2 运行mysql配置文件

  1.4.3 查看pod，服务更详细的信息

  1.4.4 登录数据库
