NGINX - Spring Boot app ( "/etc/nginx/html/index.html" is not found ) - spring

Question

So I have spring boot app that i want to put behind nginx, problem is i get Connection refused when accessing localhost.
What my nginx config looks like :
server {
listen 80;
server_name workaround;
charset utf-8;
access_log off;
location / {
proxy_pass http://172.19.0.3:8080/workaround;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $host;
}
}
What I have running :
What I get as a response when accesing localhost
404 not found. How come Its looking for some etc/nginx/html/index, when this is in my docker compose file :
nginx:
container_name: workaround-nginx
image: nginx:1.15.12-alpine
restart: always
ports:
- 80:80
- 443:443
volumes:
- ./nginx/conf.d:/etc/nginx/conf.d
- ./data/certbot/conf:/etc/letsencrypt
- ./data/certbot/www:/var/www/certbot
depends_on:
- workaround
What is wrong with my configuration? How do i properly access my SB application?
I have tried to use localhost instead of IP bud that didnt worked.
Since it used nginx ip where app is not running.
I was thinking about rewriting somehow default config of nginx bud how do i even do that from dockerfile , and then why would i have to be forced to do that when volume has mapping already set.

Answer 1

Ok i figured it out, and i even managed to fix it so it works with resources that have hash prefixes:
events {
worker_connections 1024;
}
http {
server {
listen 80;
charset utf-8;
access_log off;
try_files $uri $uri/ =404;
location / { #this still has to be here, otherwise i get ISE
proxy_pass http://workaround:8085/;
}
location ^~ { #this thing fixes hashes and resources
proxy_pass $scheme://workaround:8085/$request_uri;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
expires 30d;
}
}
}
