I'm trying to run lets-chat inside docker behind nginx acting as a reverse proxy so that lets-chat will be accessible on /chat over HTTP.

In the past when using nginx as a reverse proxy inside of docker for another docker container I set resolver 127.0.0.11 valid=300s; so that nginx uses the docker DNS server and set proxy_pass as a variable so that the nginx container can start without needing the upstream web service to be ready. Example.

However, lets-chat seems to need proxy_redirect default; which the nginx configuration does not allow combined with a variable proxy_pass.

Does anyone know a way around this to get the desired effect? I've tried a few manual redirects with no luck. My relevant nginx config is below.

# use docker's nameserver for changing container IPs
resolver 127.0.0.11 valid=300s;
resolver_timeout 5s;

server 
 listen 80;
 server_name localhost;

 location / 
 root /usr/share/nginx/html;
 index index.html index.htm;
 

 location /chat/ 
 # I would like this part to work
 #set $chat_backend http://chat_server:8080/;
 #proxy_pass $chat_backend;

 # But I can only get it to work like this
 proxy_pass http://chat_server:8080/;
 proxy_redirect / /chat/;
 proxy_redirect default; # this line errors when setting a variable to proxy_pass

 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection "upgrade";
 proxy_set_header Host $host;
 

Thanks.

From the manual, the following statements are equivalent:

location /chat/ 
 proxy_pass http://chat_server:8080/;
 proxy_redirect default;

location /chat/ 
 proxy_pass http://chat_server:8080/;
 proxy_redirect http://chat_server:8080/ /chat/;

proxy_redirect default does not work if the value of proxy_pass is not a literal string, however, proxy_redirect itself can also be constructed from variables.

So this solution may work for you:

location /chat/ 
 set $chat_backend http://chat_server:8080/;
 proxy_pass $chat_backend;

 proxy_redirect / /chat/;
 proxy_redirect $chat_backend /chat/;
 ...
