緣起

最近在公司搭建了一個基于 Gogs 的代碼管理系統，以及基于 Kanboard 的任務管理系統等幾個內部系統。由于部署在同一臺機器上，基于不同的端口區分不同的服務。比如：

Git 服務 http://10.10.1.110:10080

任務管理系統http://10.10.1.110:8888

其他

為了更好的使用，通過內部域名區分，比如 ：

Git 服務 http://gogs.vking.io

任務管理系統 http://task.vking.io

其他

注：vking.io 是內部域名，可通過 dnsmasq (http://www.thekelleys.org.uk/dnsmasq/doc.html) 配置。

方案一

現有服務都是通過 Docker 部署，nginx 同樣通過 Docker 部署，使用官方提供的鏡像即可。

新建 nginx 配置文件， nginx.conf，存放路徑為 /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;

新建反向代理設置文件 reverse-proxy.conf，存放路徑為 /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 啟動命令

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 分別指容器名稱和原始expose 的端口。

啟動容器

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 指定三個容器在同一網絡，如果用默認的 bridge的話，不需要設置

方案二

因為這些服務都是部署在一臺機器上的，可以通過 Docker 的自動服務發現部署，原理見此。

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：關鍵是容器通過 -e VIRTUAL_HOST 指定 url，通過 -e VIRTUAL_PORT=80 指定端口，同樣端口也必須是原始鏡像 expose 的端口。

延伸

目前服務都是通過 shell 啟動，可改成通過 Docker Compose 統一編排任務，把 dnsmasq+nginx+gogs+… 等統一管理。如果是部署在公網上的話，還可以把 SSL 證書到期自動刷新等一起編排。
