k8s small experiment nginx + php

Configuration storage volume nfs

-Y-utils nfs the install yum the rpcbind
## RPC services installation and service nfs
vim / etc / exports #nfs profile
/ Data / V1 10.1.1.0/24(rw,no_root_squash,no_all_squash,sync)
# to 10.1.1.0/ ip access permissions segment 24

2. Configure nginx configuration file "default.conf"

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

   location / {
             root         /usr/share/nginx/html;
             #nginx根文件地址,访问的资源都在这个文件夹里找
             index  index.html index.htm;
                     }
   location ~ \.php$ {
        root         /usr/share/nginx/html;
        #根文件地址,定义的nginx的根一样即可,同时这个地址也要和nignx一样有访问文件。
        fastcgi_pass    php.default.svc.cluster.local:9000;
        #访问后端php的地址,用内部server的dns解析,pod怎么重启都能正常访问的到
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
        fastcgi_buffers 8 16k;
        fastcgi_buffer_size 32k;
  }
     }

3.PHP profile "www.conf"
the listen = 0.0.0.0:9000
# to listen to all IP

4. Write the nginx yaml resource files nginx-php.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-php
  namespace: default
spec:
  type: NodePort
  #定义类型为NodePort,用户需要访问通过node节点的30081
  selector:
    app: web
  ports:
  - port: 80
    #service端口
    targetPort: 80
    #容器端口
    nodePort: 30081
    #node端口，如果是ClusterIP的这段不需要，也可以不填会随机
---
apiVersion: v1
kind: Pod
metadata:
  name: ngingx-php
  labels:
    app: web
spec:
  containers:
  - name: ngingx-php
    image:  nginx
    imagePullPolicy: IfNotPresent
    volumeMounts:
    - name: nginx-data
      #调用存储卷,映射到"/usr/share/nginx/html"文件夹，这里面是放nginx的访问文件的
      mountPath: /usr/share/nginx/html
    - name: nginx-conf
      #调用存储卷,映射到"/etc/nginx/conf.d"文件夹，这里面是放nginx的配置文件的
      mountPath: /etc/nginx/conf.d

  volumes:
  - name: nginx-data
    #定义Nginx访问文件存储卷
    nfs:
     path: /data/v1/data
     server: 10.1.1.111
    #存储卷是由nfs服务器10.1.1.111 提供的,"/data/v1/data"这个文件夹是真正存文件的
  - name: nginx-conf
    #定义Nginx配置文件存储卷
    nfs:
     path: /data/v1/nginx-conf
     server: 10.1.1.111

5.php yaml file php.yaml

apiVersion: v1
kind: Service
metadata:
  name: php
  namespace: default
spec:
  selector:
    app: php
  ports:
  - port: 9000
    targetPort: 9000
    #由于nginx和php都是pod 内部访问就可以了暴露内部端口即可
---
apiVersion: v1
kind: Pod
metadata:
  name: php
  labels:
    app: php
spec:
  containers:
    - name: php
      image:  phpdockerio/php56-fpm
      imagePullPolicy: IfNotPresent
      volumeMounts:
      - name: php-conf
        #调用php配置存储卷
        mountPath: /etc/php5/fpm/pool.d
      - name: php-data
        #调用nginx的存储文件夹,php也要一份nginx的访问文件,没有调用过来是无文件处理
        mountPath: /usr/share/nginx/html
  volumes:
  - name: php-conf
    nfs:
     path: /data/v1/php-conf
     server: 10.1.1.111
  - name: php-data
    nfs:
     path: /data/v1/data
     server: 10.1.1.111

6.php test file "info.php"

<?php
    phpinfo();
?>

7. Access


# 30081 to find a node of port access http://10.1.1.111:30081/info.php
