我希望能够访问同一主机上包含 Web 应用程序的多个容器。
当我想访问主机 (通过 IP 地址) 或容器 (例如通过 host_ip_adress/container1) 时,我都会收到 503 错误nginx
。我想要的是通过 ip_addrress_host/container1 访问我的容器 1。
我在网上找到的解决方案是设置一个nginx-proxy
前端服务器(来源:https://blog.florianlopes.io/host-multiple-websites-on-single-host-docker/)
我的docker-compose文件: docker-compose.yml
version: '2'
services:
nginx-proxy:
image: jwilder/nginx-proxy
ports:
- "80:80"
volumes:
- /var/run/docker.sock:/tmp/docker.sock
site_a:
image: php:7.0-apache
expose:
- "80"
environment:
- VIRTUAL_HOST=container1
volumes:
- ./php:/var/www/html
site_b:
image: php:7.0-apache
expose:
- "80"
environment:
- VIRTUAL_HOST=container2
volumes:
- ./php:/var/www/html
我用命令:
docker-compose up
我的参赛作品/etc/hosts 文件:
127.0.1.1 container1
127.0.0.1 container2
当我从外部发出请求时看到的日志:
nginx-proxy_1 | nginx.1 | 192.168.12.28 192.168.12.82 - - [25/Oct/2017:09:46:42 +0000] "GET /container1 HTTP/1.1" 503 615 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36"

谢谢你的帮助,抱歉我的英语不好!:-)
编辑 :
以下是我启动时 nginx-proxy 容器的日志:

编辑2:我尝试使用 Paweł Tatarczuk 提供的配置文件来“定制” nginx-proxy(https://serverfault.com/a/880384/441157)
现在,当我发出类似这样的请求时http://192.168.12.28/container1我得到了这个日志:
nginx-proxy_1 | nginx.1 | 2017/10/26 08:46:19 [error] 41#41: *1 open() "/etc/nginx/html/container1" failed (2: No such file or directory), client: 192.168.12.82, server: 192.168.12.28, request: "GET /container1 HTTP/1.1", host: "192.168.12.28"
编辑3:将 ? 添加到重写中
nginx-proxy_1 | nginx.1 | 2017/10/26 09:11:00 [error] 31#31: *1 container1 could not be resolved (2: Server failure), client: 192.168.12.82, server: 192.168.12.28, request: "GET /container1 HTTP/1.1", host: "192.168.12.28"
答案1
我想要的是通过 ip_addrress_host/container1 访问我的 container1。
您确定要使用例如访问容器吗http://127.0.0.1/container1? 那么就jwilder/nginx-proxy
不是最好的办法了。
您的代理正在本地监听端口 80,它将代理请求到container1
和,container2
但不会代理路径/container1
和/container2
。
卷曲
curl -H "Host: container1" localhost
浏览器
您可以附加一个自定义配置,该配置将负责处理代理路径以使ip_address/container-name
工作正常进行:
- 将其添加到
volumes
:./custom.conf:/etc/nginx/conf.d/custom.conf
custom.conf
在旁边创建docker-compose.yml
:server { server_name 192.168.X.Y; listen 80; location ~ ^/([^/]+)(/.*)? { proxy_pass http://$1$2; } }
链接容器
nginx-proxy: ... links: - site_a:container1 - site_b:container2
这只是开始,你应该改进它以满足你的需求。它应该适用于http://192.168.XY/container1或者http://192.168.XY/container2。
请注意,有一个重写,因此http://192.168.XY/container1/some/path代理至 http://container1/some/path。我假设您不想要带有/container1
前缀的请求到您的目标容器。
