[系统运维]k8s搭建nginx文件服务器（遗留问题明天解决） 7月21日学习笔记

关于k8s配置nginx并创建本地目录

首先分享一下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
       volumes:
        - name: nginx-conf
          configMap: 
            name: nginx-configmap
       volumes:
        - name: data
          hostPath:
            path: /opt/data
---
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 

---
apiVersion: v1
data:
  default.conf: |-
    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /files;
            autoindex on;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
kind: ConfigMap
metadata: 
  name: nginx-configmap

这里通过hostoath的方式映射两个目录

usr/share/nginx/html ----/opt/data
/etc/nginx/ ----opt/conf
注意点：
在node节点需要往映射目录创建index.html

疑问：
只创建data目录
cm未生效

明天处理
