Can I make code server access on a sub path?

[imran0]

I run code server on a docker container which I access from various machines using http://machine-name.local:8080.
Is it possible to serve the site on http://machine-name.local/code? When I try to proxy it using NGINX it doesn't work.

Sure, that should work. Something like this, I think:

   server {
       listen 80;
       listen [::]:80;
       server_name machine-name.local;

       location /code {
         proxy_pass http://localhost:8080/;
         proxy_set_header Host $http_host;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection upgrade;
         proxy_set_header Accept-Encoding gzip;
       }
   }

Note that the trailing slash in proxy_pass is important, it tells NGINX to rewrite the path which code-server requires.

I have the following setup following your example but when I type in http://diskstation/code, it redirects to http://diskstation/?folder=/workspace/docker/projects. When I do http://diskstation.local/code, it redirects to http://diskstation.local/login. In both redirects the page lands on a 404 page.

server {
    listen 80;
    listen [::]:80;
    server_name diskstation.local diskstation.sugar-thorn.ts.net diskstation;

    # Common proxy settings
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_redirect off;

    location /code {
        proxy_pass http://localhost:8443/;
        proxy_set_header Host $http_host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection upgrade;
        proxy_set_header Accept-Encoding gzip;
    }

    location /other-app {
        proxy_pass http://localhost:8988;
    }
...

Any ideas what I'm doing wrong?

I get 401 not found when I try diskstatation.local/code/

[code-asher]

Are you sure it is 401 not found? That is an unusual combination of code and status.

Can you verify whether the error is coming from code-server or NGINX?

[imran0]

Sorry I'm mistaken, its a 404 header. The page is black and theres some white text which says says "Not found" when I hit https://diskstation/code/
When I hit https://diskstation/code without the trailing slash, I see the URL is redirected to http://diskstation/?folder=/workspace/docker/projects it it shows a 404 Not Found page, but it looks like a generic nginx 404 page unlike the first URL.

[code-asher]

I tried it out and got the same error. It looks like NGINX is sending requests with double slashes like //login for some reason. I was able to get it working like this:

location = /code {
  return 302 /code/$is_args$args;
}
location /code/ {
  proxy_pass http://localhost:8080/;
  proxy_set_header Host $http_host;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection upgrade;
  proxy_set_header Accept-Encoding gzip;
}

This has got it working! Thank you!
