k8s啟動nginx服務

本次需要啟動的是一個通過nginx實現的靜態文件服務器。

創建命名空間腳本create_shjujubu_namespace.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: shujubu
  labels:
    name: shujubu

 

執行文件創建 shujubu命名空間：

kubectl create -f  create_shjujubu_namespace.yaml

 

需要的鏡像列表：

nginx                                                                      1.17                62c261073ecf        3 months ago        109MB

 

定義pod文件 nginx-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: sjb-nginx
  namespace: shujubu
  labels:
    name: sjb-nginx
spec:
  containers:
  - name: nginx
    image: ccr.ccs.tencentyun.com/shujubu/nginx:1.17
    imagePullPolicy: IfNotPresent
    ports:
    - containerPort: 80
    volumeMounts:
    - mountPath: /etc/nginx/nginx.conf
      name: config
    - mountPath: /etc/nginx/conf.d/default.conf
      name: default
    - mountPath: /var/log/nginx/
      name: log
    - mountPath: /usr/share/nginx/shzr/area
      name: shzr
    - mountPath: /usr/share/nginx/zgbs/mujun
      name: mujun
    - mountPath: /usr/share/nginx/zgbs/area
      name: zgbs

  restartPolicy: Never

  volumes:                                                                                                                                                                                           
  - name: config
    hostPath:
      path: /home/users/qix/sjb_bs_source/nginx/nginx.conf
  - name: default
    hostPath:
      path: /home/users/qix/sjb_bs_source/nginx/conf.d/default.conf
  - name: log
    hostPath:
      path: /home/users/qix/sjb_bs_source/nginx/log/
  - name: shzr
    hostPath:
      path: /home/users/qix/sjb_bs_source/shzr/area/
  - name: mujun
    hostPath:
      path: /home/users/qix/sjb_bs_source/zgbs/mujun/
  - name: zgbs
    hostPath:
      path: /home/users/qix/sjb_bs_source/zgbs/area/

 

 

上面的pod中只定義了一個容器，並在容器中掛載了nginx的配置文件、日志文件及我們要訪問的資源文件。

定義service文件 nginx-np.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx
spec:
  selector:
    name: sjb-nginx
  type: NodePort
  ports:
    - protocol: TCP
      port: 10008
      targetPort: 80
      nodePort: 30008

 

注意，service中的selector中的配置要與pod中的labels保持一致。

並附上nginx.conf中的部分配置

user  root;
worker_processes  1;

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    gzip  on;
    gzip_min_length 1024K;   # 大於1M的壓縮
    gzip_comp_level 5;    # 壓縮級別 1-10 數字越大壓縮的越好
    gzip_types text/plain application/x-javascript text/css application/xml application/json text/javascript application/x-httpd-php image/jpeg image/gif image/png;   # 壓縮的文件類型

    server {
        listen       80;
        server_name  192.168.111.36:80;
        location / {
            root /usr/share/nginx/html;
            index index.html;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
        location ^~ /shzr/area/ {
            root /usr/share/nginx/;
            autoindex on;
        }
        location ^~ /zgbs/mujun/ {
            root /usr/share/nginx/;
            autoindex on;
        }
        location ^~ /zgbs/area/ {
            root /usr/share/nginx/;
            autoindex on;
        }
    }
}

 

啟動pod命令：

kubectl create -f nginx-pod.yaml -n shujubu

 

啟動service命令：

kubectl create -f nginx-np.yaml -n shujubu

 

大功告成！訪問http://IP:30008/查看nginx服務是否正常：
