docker - How to rewrite or proxy url in nginx? -


i new in nginx. want rewrite 

feature-1234.mydomain.com/xyz?foo=bar

to

docker-feature-1234:9000/xyz?foo=bar

with request parameters.

i use official nginx docker image. how should nginx.conf file?

edit: 'feature-1234' variable so:

feature-5678.mydomain.com

should serve 

docker-feature-5678:9000

by combining answers, found solution.

docker network nginx resolver

nginx: [emerg] "server" directive not allowed here

nginx.conf:

events { }  http {   server {     listen 80;     server_name ~(.*).test.go;      location / {       if ($host ~* ^([a-za-z0-9-]+)\.test\.go$) {         set $proxyhost docker-$1:9000;       }        resolver 127.0.0.11 ipv6=off;       proxy_pass http://$proxyhost;       proxy_http_version 1.1;       proxy_set_header upgrade $http_upgrade;       proxy_set_header x-forwarded-for $remote_addr;       proxy_set_header x-real-ip $remote_addr;       proxy_set_header host $host;      }   } }
