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


 
apiVersion: v1
kind: Pod
metadata:
  name: php-pod
spec:
  containers:
    - name: fpm
      image: php-fpm
      ports:
        - name: web
          containerPort: 80
      lifecycle:
        preStop:
          exec:
            command:
              - sh
              - '-c'
              - sleep 5 && kill -SIGQUIT 1 //通过此种方式 处理pod删除时 未完成的请求
    - name: nginx
      image: nginx
      ports:
        - name: http
          containerPort: 80
      lifecycle:
        preStop:
          exec:
            command:
              - sh
              - '-c'
              - sleep 5 && /usr/sbin/nginx -s quit
  terminationGracePeriodSeconds: 30
