Is there a better way? Nginx config on subdirectory/url path

Configuration Frontend

I managed to configure Nginx to load the HA dashboard on a subdirectory (public-url-addr /homeassistant), and with some minor hickups, it is working.

The issue I have is that I had to configure a location for each subdirectory that HA uses individually. It might break in the future, would need to add/remove other url paths if stuff change, could potentially break other stuff on my home server etc.

How did others do it? Is there a better way of doing this as subdirectory?

Here is the HA part in my current nginx config:

 location = /homeassistant {
     port_in_redirect off;
     rewrite ^ /homeassistant/ permanent;
 }
 location /homeassistant/ {
     proxy_set_header Host openmediavault.local:8123;
     proxy_set_header X-Forwarded-Host $http_host;
     proxy_set_header X-Forwarded-For $remote_addr;
     proxy_http_version 1.1;
     proxy_cookie_path / "/; Secure";

     proxy_pass http://openmediavault.local:8123/;
 }
 location /static/ {
     proxy_set_header Host openmediavault.local:8123;
     proxy_set_header X-Forwarded-Host $http_host;
     proxy_set_header X-Forwarded-For $remote_addr;
     proxy_http_version 1.1;
     proxy_cookie_path / "/; Secure";

     proxy_pass http://openmediavault.local:8123/static/;
 }
 location /frontend_latest/ {
     proxy_set_header Host openmediavault.local:8123;
     proxy_set_header X-Forwarded-Host $http_host;
     proxy_set_header X-Forwarded-For $remote_addr;
     proxy_http_version 1.1;
     proxy_cookie_path / "/; Secure";

     proxy_pass http://openmediavault.local:8123/frontend_latest/;
 }
 location /auth/ {
     proxy_set_header Host openmediavault.local:8123;
     proxy_set_header X-Forwarded-Host $http_host;
     proxy_set_header X-Forwarded-For $remote_addr;
     proxy_http_version 1.1;
     proxy_cookie_path / "/; Secure";

     proxy_pass http://openmediavault.local:8123/auth/;
 }
 location /api/ {
     proxy_set_header Host openmediavault.local:8123;
     proxy_set_header X-Forwarded-Host $http_host;
     proxy_set_header X-Forwarded-For $remote_addr;
     proxy_http_version 1.1;
     proxy_cookie_path / "/; Secure";

     proxy_set_header Upgrade $http_upgrade;
     proxy_set_header Connection "upgrade";

     proxy_pass http://openmediavault.local:8123/api/;
 }

Note: I’m running the HA in Docker container on my home OpenMediaVault server.
