I install nginx in one container then install gitlab in another container;
I also create a custom network bridge with them;
I config reverse proxy but it dosen’t work
is there any document I can read? or anybody help me?

docker run -p 80:80 --name nginx -v /root/docker/nginx/html:/usr/share/nginx/html -v /root/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx

docker run -d -h gitlab -p 8100:80 -p 8200:443 -p 8300:22 -v /docker/gitlab/config:/etc/gitlab -v /docker/gitlab/logs:/var/log/gitlab -v /docker/gitlab/data:/var/opt/gitlab --name gitlab gitlab/gitlab-ce:latest

	####Gitlab
server {
        listen       80;
        server_name  gitlab.localserver.com;
        
        charset utf-8;
        #access_log  logs/host.access.log  main;

        #对 / 所有做负载均衡+反向代理
        location / {
        #    root   /apps/oaapp;
        #    index  index.jsp index.html index.htm;

            proxy_pass        http://gitlab:8100;
			#proxy_pass        http://nexus:8081;
            proxy_redirect off;
            # 后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
            proxy_set_header  Host  $host;
            proxy_set_header  X-Real-IP  $remote_addr;  
            proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
