Nginx - Reverse proxy - 404 - nginx

Question

Receive 404 error while calling URL - http://10.240.0.133/swagger. Below is the snippet of nginx.conf file, I need to append index.html at end of the URI, so I placed a rewrite rule.
server {
listen 80;
listen [::]:80;
server_name localhost;
server_name 10.240.0.133;
server_name 127.0.0.1;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
access_log /var/log/nginx/resources-reverse-access.log;
error_log /var/log/nginx/resources-reverse-error.log;
location /swagger {
rewrite ^/swagger/index.html break;
proxy_pass http://52.177.131.103:8082/;
}
}
When I visited the URL - curl -v http://10.240.0.133/swagger
404 is thrown:-
* Trying 10.240.0.133...
* TCP_NODELAY set
* Connected to 10.240.0.133 (10.240.0.133) port 80 (#0)

Answer 1

I believe your rewrite rule is incorrect. It should look more like this.
location /swagger {
rewrite ^\/swagger\/?.*?$ /swagger/index.html break;
proxy_pass http://52.177.131.103:8082/;
}
but I believe this still not correct since you have not a set a root directive for this server.
