java - How to run "Eclipse Che" behind NGINX reverse proxy? -

i have installed on server eclipse che , runs on machine when use locally localhost:8080

i make available internet, behind nginx front reverse proxy. here idea:

example.com/che/ ---> nginx reverse proxy ---> server:8080/

i tried many different nginx configuration... without success. information, eclipse che embeds tomcat instance rewrite rules:

rewriterule ^/api/ext/(.*)$ /ide/ext/$1 [l] rewriterule ^/api/(.*)$ /ide/api/$1 [l] rewriterule ^/$ /dashboard [r] 

there 3 webapps deployed on tomcat server:

ide dashboard  swagger 

if eclipse che behind nginx, above rewrite rules useless , can done directly nginx (that's did)

i have 1 single block in nginx configuration (if possible) here tried far, it's not working , eclipse che not load (my guess websockets not proxified, , miss something) basically, tried "proxypass" different webapps, may not best option.

location /dashboard {  proxy_pass http://localhost:8080/dashboard;  proxy_redirect off;  proxy_set_header host $host;  proxy_set_header x-real-ip $remote_addr;  proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for; } location /ide {  proxy_pass http://localhost:8080/ide;  proxy_redirect off;  proxy_set_header host $host;  proxy_set_header x-real-ip $remote_addr;  proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for; } location /api {  rewrite ^/api/ext/(.*)$ /ide/ext/$1 redirect;  rewrite ^/api/(.*)$ /ide/api/$1 redirect; } 

you can notice added rewrite rules in nginx "api" location rather in tomcat configuration (root webapp) help.

fyi http://nginx.org/ru/docs/http/websocket.html have add websocket connection upgrade specific conf:

map $http_upgrade $connection_upgrade {             default upgrade;             ''      close;         }  proxy_http_version 1.1; proxy_set_header upgrade $http_upgrade; proxy_set_header connection $connection_upgrade;
