k8s启动nginx服务

本次需要启动的是一个通过nginx实现的静态文件服务器。

创建命名空间脚本create_shjujubu_namespace.yaml

apiVersion: v1

kind: Namespace

metadata:

name: shujubu

labels:

name: shujubu

执行文件创建 shujubu命名空间：

kubectl create -f create_shjujubu_namespace.yaml

需要的镜像列表：

nginx 1.17 62c261073ecf 3 months ago 109MB

定义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中只定义了一个容器，并在容器中挂载了nginx的配置文件、日志文件及我们要访问的资源文件。

定义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中的配置要与pod中的labels保持一致。

并附上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; # 大于1M的压缩

gzip_comp_level 5; # 压缩级别 1-10 数字越大压缩的越好

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; # 压缩的文件类型

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;

}

}

}

启动pod命令：

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

1

启动service命令：

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

1

大功告成！访问http://IP:30008/查看nginx服务是否正常：

访问其中一个静态文件：
