How to Proxy Multiple Code-Servers via Nginx?

[yuzhuoheng]

I have multiple code-servers deployed in Docker containers. They are located at 127.0.0.1:13001, 127.0.0.1:13002, and so on. How can I achieve this through Nginx? For example, accessing /code/13001 should forward to 127.0.0.1:13001, and accessing /code/13002 should forward to 127.0.0.1:13002. It's important to note that the ports I mentioned (e.g., 13001) are not fixed.

I tried using the following configuration, but the browser cannot open the page normally.

I think once you use a regex you have to tell NGINX what the full target is, but I am not sure. This seems to work for me:

proxy_pass http://127.0.0.1:$1$2$is_args$args;

Thank you very much for being willing to help me!! But I still haven't solved it。

I have modified nginx according to your suggestion and hope to use/vscode/31013/proxy to access it http://127.0.0.1:31013

After the nginx - s reload, I accessed it using a browser http://192.168.8.74:31013/ , can be accessed normally

But I use https://vscode.rd.supcon.com/vscode/31013/ The page displays' not found '

To verify if there is an issue with nginx, I will follow your answers in other posts. Added a section of ngixn configuration:

After nginx - s reload, access it again through the browser: https://vscode.rd.supcon.com/code/ , can be accessed normally

Your location is a little different than what you originally posted. This is what I was using (notice the $2):

location ~/code/(\d+)(/.*)?$ {
  proxy_pass http://127.0.0.1:$1$2$is_args$args;
  proxy_set_header ... etc etc ....

But, I was able to make ~ ^/vscode/(.*)/?$ work by omitting the slash in proxy_pass:

location ~ ^/vscode/(.*)/?$ { 
  proxy_pass http://127.0.0.1:$1$is_args$args; 
  proxy_set_header ... etc etc ....

I used your configuration:

When I opened the following URL in my browser: https://hos-studio.rd.supcon.com/vscode/15555/

I noticed that the page resources loaded correctly, but its WebSocket was not properly forwarded.

Make sure to include all the other headers as well. NGINX will not forward web sockets without Upgrade and Connection. I would include Host and Accept-Encoding as well.
