[系统运维]k8s搭建nginx文件服务器成功（解答昨天的问题）7月22日学习笔记

首先，附上最终版yaml文件

apiVersion: apps/v1
kind: Deployment
metadata: 
   name: nginx-deployment
   namespace: default
   labels: 
     app: nginx-test
spec:
   selector:
     matchLabels:
       app: nginx-test
   replicas: 3
   template: 
     metadata:
       name: nginx-test
       labels: 
         app: nginx-test
     spec:
       containers:
        - name: nginx-container
          image: nginx
          imagePullPolicy: IfNotPresent
          ports:
          - containerPort: 80
         # volumeMounts: 
         # - mountPath: /etc/nginx/conf.d/default.conf
         #   name: nginx-conf
         #   subPath: default.conf
          volumeMounts:
          - mountPath: /usr/share/nginx/html/
            name: data	
          - mountPath: /etc/nginx/
            name: nginxconf
      # volumes:
      #  - name: nginx-conf
      #    configMap: 
      #      name: nginx-configmap
       volumes:
        - name: data
          hostPath:
            path: /opt/nginxdata/
            type: Directory
        - name: nginxconf
          hostPath:
            path: /opt/nginxconf/
            type: Directory
---
apiVersion: v1
kind: Service
spec:
    ports:
    - nodePort: 30030
      port: 8080
      targetPort: 80
    type: NodePort
    selector:
      app: nginx-test
metadata: 
    namespace: default
    labels: 
      app: nginx-test
    name: nginx-service 

注意点：

1. type: Directory这个好像是必填的，之前做的实验都失败了，不确定是不是因为这个
2. 这里的hostPath要提前到节点上去创建，否则是不会创建的
3. 这里要写成数组的形式，不确定是不是因为这个
4. nginx配置文件location字段中，要加autoindex on；否则会默认找index.html 找不到就403了

         - mountPath: /usr/share/nginx/html/
           name: data	
         - mountPath: /etc/nginx/
           name: nginxconf
      volumes:
       - name: data
         hostPath:
           path: /opt/nginxdata/
           type: Directory
       - name: nginxconf
         hostPath:
           path: /opt/nginxconf/
           type: Directory

验证

到了愉快的验证环节

不容易啊，describe一下看看
这里也是没问题的~

实现目标

1. 实现共享存储，即本地与容器共享存储，后续可本地修改配置文件，？持久化存储，NONO，持久化存储还是上pvc，pv吧，后续会学习这一方面
2. 关机睡觉~
