docker中nginx配置反向代理

将容器/etc/nginx/conf.d/default.conf复制到宿主主机中

docker cp 容器id:/etc/nginx/conf.d/nginx.conf /home

编辑该文件为如下内容：

upstream local_tomcat{
        server 172.17.0.3:8080;
        server 172.17.0.4:8080;
}

server {
        listen 80;
        server_name localhost;
        
        location / {
                proxy_pass http://local_tomcat;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header REMOTE-HOST $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

再将该文件复制回原来的容器中，替换源文件：

docker cp /home/default.conf d24b775334da:/etc/nginx/conf.d/

最后从其docker的nginx容器

docker restart 容器id
