k8s集群中部署微服务项目前端代理服务 Nginx

一、微服务项目静态资源准备

# mkdir sangomall-proxy
# cd sangomall-proxy/

[root@k8s-master01 sangomall-proxy]# ls
conf  Dockerfile  html  html.tar.gz

[root@k8s-master01 sangomall-proxy]# cd conf/
[root@k8s-master01 conf]# ls
default.conf
[root@k8s-master01 conf]# vim default.conf
[root@k8s-master01 conf]# cat default.conf

upstream sangomall {
      server mall-gateway.sangomall.svc.cluster.local.:8072;
    }

server {
    listen       80;
    server_name  *.msb.com;

    #access_log  /var/log/nginx/host.access.log  main;

    location /static/ {
       root   /usr/share/nginx/html;
    }

    location / {
       proxy_set_header Host $host;
       proxy_pass http://sangomall;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

[root@k8s-master01 sangomall-proxy]# ls
conf  Dockerfile  html  html.tar.gz
[root@k8s-master01 sangomall-proxy]# cd html
[root@k8s-master01 html]# ls
es  index.html  static
[root@k8s-master01 html]# cat es/fenci.txt
sango
mall
[root@k8s-master01 html]# cat index.html
<h1>sangomall </h1>

[root@k8s-master01 html]# ls static
cart  index  item  login  order  reg  search

[root@k8s-master01 sangomall-proxy]# cd html/
# tar czvf html.tar.gz *

[root@k8s-master01 sangomall-proxy]# mv html.tar.gz ../

[root@k8s-master01 sangomall-proxy]# vim Dockerfile
[root@k8s-master01 sangomall-proxy]# cat Dockerfile
FROM nginx

MAINTAINER nextgo@126.com

RUN rm -rf /etc/nginx/conf.d/*

COPY conf/* /etc/nginx/conf.d/

ADD html.tar.gz  /usr/share/nginx/html/

EXPOSE 80

ENTRYPOINT nginx -g "daemon off;"

二、微服务项目前端代理服务镜像制作

[root@k8s-master01 sangomall-proxy]# docker build -t docker.io/nextgomsb/nginx:v1 .

[root@k8s-master01 sangomall-proxy]# docker images
REPOSITORY                                TAG       IMAGE ID       CREATED         SIZE
nextgomsb/nginx                           v1        f83f673f91df   4 seconds ago   173MB

[root@k8s-master01 sangomall-proxy]# docker login

[root@k8s-master01 sangomall-proxy]# docker push docker.io/nextgomsb/nginx:v1

三、微服务项目前端代理服务部署及访问

四、添加微服务访问路由规则

五、添加域名解析

[root@dnsserver ~]# cat /var/named/msb.com.zone
$TTL 1D
@       IN SOA  msb.com admin.msb.com. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
