使用jwilder nginx-proxy,如何将子目录url代理传递到特定容器? [英] With jwilder nginx-proxy, how to proxypass a subdirectory url to a specific container?
问题描述
我使用 jwilder/nginx-proxy 做反向代理.我尝试将http://localhost:8000/api
重定向到特定的php服务.
I use jwilder/nginx-proxy to make a reverse proxy. I try to redirect http://localhost:8000/api
to a specific php service.
目录结构:
.
+-- docker-compose.yml
+-- nginx
+-- nodejs
| +-- index.js
| +-- …
+-- php
| +-- api
docker-compose.yml:
docker-compose.yml:
version: "3.1"
services:
nginx-proxy:
image: jwilder/nginx-proxy:alpine
ports:
- "8000:80"
volumes:
- ./php:/srv/www
- /var/run/docker.sock:/tmp/docker.sock:ro
nodejs:
image: node:alpine
environment:
- NODE_ENV=production
- VIRTUAL_HOST=localhost
- VIRTUAL_PORT=8080
expose:
- "8080"
working_dir: /home/app
restart: always
volumes:
- ./nodejs:/home/app
command: ["node", "index.js"]
php:
image: php:apache
environment:
- VIRTUAL_HOST=localhost
volumes:
- ./php:/var/www/html
这对于nodejs
服务正常工作.
This works fine for the nodejs
service.
现在,我想将对http://localhost:8000/api
的调用重定向到php
服务.我想我必须在nginx conf
中添加以下内容:
Now, I would like to redirect calls to http://localhost:8000/api
to the php
service. I imagine that I have to add to the nginx conf
something like:
server {
location /api {
proxy_pass http://php:80/api;
proxy_set_header Host $host;
}
}
此功能未内置在库中. 那么,我该如何实现呢?
This feature is not built into the lib. So, how can I achieve that?
推荐答案
一种方法是为php应用提供自己的虚拟主机:
One approach is to give the php app its own virtual host:
php:
image: php:apache
environment:
- VIRTUAL_HOST=api.localhost
volumes:
- ./php:/var/www/html
然后,它将是可访问的:
Then, it will be accesible as this:
curl -H 'Host: api.localhost' http://localhost:8000/api
几乎可以用任何一种语言来设置标题.或者,为避免设置自定义标头,您可以将该DNS添加到您的/etc/hosts
文件中:
Setting the header can be achieved in practically any language. Or to avoid setting custom header, you can add that DNS to your /etc/hosts
file:
127.0.0.1 api.localhost
因此,您可以像这样卷曲:
So you can curl as this:
curl -H http://api.localhost:8000/api
这是设置自定义标头的方式,例如在节点中:
This is how set custom headers, for example in node:
var request = require('request')
var formData = {}
request({
headers: {
'Host': 'api.localhost'
},
uri: 'http://localhost:8080',
method: 'POST'
}, function (err, res, body) {
console.log("it works")
console.log(res)
}
)
但是,我建议您采用/etc/hosts方法,该方法在生产环境(DNS服务器)中应该等效.因此,您无需触摸节点代码.
But, I recommend you to go for the /etc/hosts approach, that should has an equivalent in production environment (a DNS server). So you don't need to touch node code.
