Dockernginx反向代理设置

最近在公司搭建了一个基于 Gogs 的代码管理系统，以及基于 Kanboard 的任务管理系统等几个内部系统。由于部署在同一台机器上，基于不同的端口区分不同的服务。比如：

• Git 服务 http://10.10.1.110:10080
• 任务管理系统http://10.10.1.110:8888
• 其他

为了更好的使用，通过内部域名区分，比如 ：

• Git 服务 http://gogs.vking.io
• 任务管理系统 http://task.vking.io
• 其他

方案一

现有服务都是通过 Docker 部署，nginx 同样通过 Docker 部署，使用官方提供的镜像即可。

• 新建 nginx 配置文件， nginx.conf，存放路径为 /srv/docker/nginx/nginx.conf

# user nginx; worker_processes auto; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; } # daemon off; 

• 新建反向代理设置文件 reverse-proxy.conf，存放路径为 /srv/docker/nginx/conf.d/reverse-proxy.conf

# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the # scheme used to connect to this server map $http_x_forwarded_proto $proxy_x_forwarded_proto { default $http_x_forwarded_proto; '' $scheme; } # If we receive X-Forwarded-Port, pass it through; otherwise, pass along the # server port the client connected to map $http_x_forwarded_port $proxy_x_forwarded_port { default $http_x_forwarded_port; '' $server_port; } # If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any # Connection header that may have been passed to this server map $http_upgrade $proxy_connection { default upgrade; '' close; } # Apply fix for very long server names server_names_hash_bucket_size 128; # Default dhparam ssl_dhparam /etc/nginx/dhparam/dhparam.pem; # Set appropriate X-Forwarded-Ssl header map $scheme $proxy_x_forwarded_ssl { default off; https on; } gzip_types text/plain text/css application/javascript application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; log_format vhost '$host $remote_addr - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent ' '"$http_referer" "$http_user_agent"'; access_log off; # HTTP 1.1 support proxy_http_version 1.1; proxy_buffering off; proxy_set_header Host $http_host; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $proxy_connection; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $proxy_x_forwarded_proto; proxy_set_header X-Forwarded-Ssl $proxy_x_forwarded_ssl; proxy_set_header X-Forwarded-Port $proxy_x_forwarded_port; # Mitigate httpoxy attack (see README for details) proxy_set_header Proxy ""; server { server_name _; # This is just an invalid value which will never trigger on a real hostname. listen 80; access_log /var/log/nginx/access.log vhost; return 503; } # gogs.vking.io upstream gogs.vking.io { # gogs server gogs:3000; } server { server_name gogs.vking.io; listen 80; location / { proxy_pass http://gogs.vking.io; } access_log /var/log/nginx/access.log vhost; } # task.vking.io upstream task.vking.io { # kanboard server kanboard:80; } server { server_name task.vking.io; listen 80; location / { proxy_pass http://task.vking.io; } access_log /var/log/nginx/access.log vhost; } 

gogs 启动命令

docker container run -d --name gogs \ --restart always \ -p 10022:22 \ -p 10080:3000 \ --network gogs-net \ -v /srv/docker/gogs:/data \ gogs/gogs:latest 

注： upstream gogs.vking.io 中的 server 中的 gogs:3000 分别指容器名称和原始expose 的端口。

• 启动容器

docker container run -d --name nginx \ --restart always \ -p 80:80 \ --network gogs-net \ -v /srv/docker/nginx/nginx.conf:/etc/nginx/nginx.conf \ -v /srv/docker/nginx/conf.d:/etc/nginx/conf.d \ nginx:alpines 

注：–network gogs-net 指定三个容器在同一网络，如果用默认的 bridge的话，不需要设置

方案二

因为这些服务都是部署在一台机器上的，可以通过 Docker 的自动服务发现部署，原理见此。

• gogs

docker container run -d --name gogs \ --restart always \ -p 10022:22 -p 10080:3000 \ --network gogs-net \ -e VIRTUAL_HOST=gogs.vking.io \ -e VIRTUAL_PORT=3000 \ -v /opt/docker/gogs:/data \ gogs/gogs:latest 

• Kanboard

docker container run -d --name kanboard \ --restart always \ -p 8888:80 \ --network gogs-net \ -e VIRTUAL_HOST=task.vking.io \ -e VIRTUAL_PORT=80 \ -v /srv/docker/kanboard/data:/var/www/app/data \ -v /srv/docker/kanboard/plugins:/var/www/app/plugins \ kanboard/kanboard:latest 

• nginx

docker container run -d --name nginx \ --restart always \ -p 80:80 \ --network gogs-net \ -v /var/run/docker.sock:/tmp/docker.sock:ro \ jwilder/nginx-proxy:alpine 

注：关键是容器通过 -e VIRTUAL_HOST 指定 url，通过 -e VIRTUAL_PORT=80 指定端口，同样端口也必须是原始镜像 expose 的端口。

目前服务都是通过 shell 启动，可改成通过 Docker Compose 统一编排任务，把 dnsmasq+nginx+gogs+… 等统一管理。如果是部署在公网上的话，还可以把 SSL 证书到期自动刷新等一起编排。
