k8s nginx-php 环境部署

环境基于minikube
configmap.yaml nginx配置

kind: ConfigMap # 对象类型
apiVersion: v1 # api 版本
metadata: # 元数据
  name: nginx-config # 对象名称
data: # key-value 数据集合
  nginx.conf: | 
    events {
    }
    http {
      server {
        listen 80 default_server;
        listen [::]:80 default_server;
        root /var/www/html; #php 与 nginx 的目录必须相同
        index index.php;
        server_name _;
        location / {
          try_files $uri $uri/ =404;
        }
        location ~ \.php$ {
          include fastcgi_params;
          fastcgi_param REQUEST_METHOD $request_method;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; #注意目录
          fastcgi_pass 127.0.0.1:9000;
        }
      }
    }

php-fpm.yaml nginx fpm共用一个pod 这样127.0.0.1:9000能访问到

kind: Deployment # 对象类型
apiVersion: apps/v1 # api 版本
metadata: # 元数据
  name: php-fpm-nginx # Deployment 对象名称
spec: # Deployment 对象规约
  selector: # 选择器
    matchLabels: # 标签匹配
      app: php-fpm-nginx
  replicas: 1 # 副本数量
  template: # 模版
    metadata: # Pod 对象的元数据
      labels: # Pod 对象的标签
        app: php-fpm-nginx
    spec: # Pod 对象规约
      containers: # 这里设置了两个容器
        - name: php-fpm # 第一个容器名称
          image: hejinxue/fpm:v1 # 容器镜像 已经把代码打包到镜像中
          ports:
            - containerPort: 9000 # php-fpm 端口
　　　　　 envFrom:
　　　　　　　- secretRef:
　　　　　　　　　　name: mysecret #把敏感的数据信息放入$_SERVER
　　　　　　

        - name: nginx # 第二个容器名称
          image: hejinxue/nginx:v1 # 容器镜像 创建了默认的index.php空文件
          ports:
            - containerPort: 80 # nginx 端口
          volumeMounts:
            - mountPath: /etc/nginx/nginx.conf #  挂载配置了 nginx.conf 的 volume
              subPath: nginx.conf
              name: nginx-config
      volumes:
        - name: nginx-config 
          configMap: 
            name: nginx-config

 

kubectl expose deployment php-fpm-nginx --type=NodePort --port=80  暴露80端口 会创建Service

 

创建nginx—ingress

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  rules:
    - host: hello-world.info
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: php-fpm-nginx
                port:
                  number: 80

创建Secret

apiVersion: v1
kind: Secret
metadata:
  name: mysecret
type: Opaque
data:
  USER_NAME: YWRtaW4=
  PASSWORD: MWYyZDFlMmU2N2Rm
