Nginx reverse proxy for tomcat

Finally figured it out. The app has a filter that redirects to /webapp/index.html , which made nginx make the request for /webapp/webapp/index.html which was giving the 404.

I added a rewrite rule

location / {                proxy_pass  https://backend/webapp/;                proxy_redirect off;                proxy_set_header   Host             $host;                proxy_set_header   X-Real-IP        $remote_addr;                proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;                rewrite ^/webapp/(.*)$ /$1 last;}

And this seems to be working for now !

full nginx config to pass to tomcat context :

server {  listen 80;         # e.g., listen 192.168.1.1:80; In most cases *:80 is a good idea  listen [::]:80;  server_name tomcat-context.domain.com ;  # individual nginx logs for this vhost  access_log  /var/log/nginx/tomcat-context_domain_access.log main;  error_log   /var/log/nginx/tomcat-context_domain_error.log;    error_page 500 502 503 504 /50x.html;    location = /50x.html {        root /usr/share/nginx/www;    }    location / {                proxy_pass  http://127.0.0.1:10080/tomcat-context/;                proxy_redirect off;                proxy_set_header   Host             $host;                proxy_set_header   X-Real-IP        $remote_addr;                proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;                rewrite ^/tomcat-context/(.*)$ /$1 last;    }    location /tomcat-context {      rewrite ^/tomcat-context(.*)$ $1  redirect;    }}
