第1章 nginx配置文件yaml
1.1 nginx _rc文件数据持久化（rc资源类型）

cat nginx_rc.yaml
apiVersion: v1
kind: ReplicationController
metadata:
  name: nginx4
spec:
   replicas: 1
   selector:
     app: nginx4
   template:
     metadata:
       labels:
         app: nginx4
     spec:
       containers:
       - name: nginx4
         image: 10.0.0.10:5000/nginx:v2
         ports:
         - containerPort: 80
         volumeMounts:
          - mountPath: /usr/local/nginx/html     #容器的站点目录
            name: web
       volumes:
        - hostPath:
           path: /root/test                      #本地（宿主机）目录
          name: web

1.2 nginx_service文件

apiVersion: v1
kind: Service
metadata:
  name: nginx4
spec:
  type: NodePort
  ports:
   - port: 80
     nodePort: 30082
  selector:
    app: nginx4

1.3 nginx_rc文件（pod资源类型）不需要创建service文件即可外部访问

[[email protected] nginx1]# cat nginx-rc.yaml
apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    name: nginx
spec:
  containers:
  - name: nginx
    image: nginx
    ports:
    - containerPort: 80        #源端口
      hostPort: 80             #宿主机映射端口

1.4 nginx数据持久化（基于nfs实现）

cat /docker/nginx_rc/nginx-rc.yaml
apiVersion: v1
kind: ReplicationController
metadata:
  name: nginx2
spec:
   replicas: 1
   selector:
     app: nginx2
   template:
     metadata:
       labels:
         app: nginx2
     spec:
       containers:
       - name: nginx2
         image: nginx
         ports:
         - containerPort: 80
         volumeMounts:
         - mountPath: /usr/share/nginx/html
           readOnly: false
           name: nginx-data
       volumes:
       - name: nginx-data
         nfs:
           server: 192.168.1.89
           path: "/app/www_data"
