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.
