How do I change generated local address url in port forwarding?

[Wireless4024]

I'm using code-server in coder,
by default auto forward will generate local address such as http://localhost:{PORT}, coder have config to use wildcard subdomain but I don't want to use it.
so I want to change it to be something like {CURRENT_URL}/proxy/{PORT} instead, how do I achieve this? (url that I want is accessible if I type it manually)

if this is coder's problem or have soluion to do please let me know.

Great question! Apologies for not having this in the docs or easier to find. This is where it's documented: https://github.com/coder/code-server/releases/tag/v4.8.0

So you'll want to set VSCODE_PROXY_URI=https://your-url/proxy/{{port}} as an environment variable. Let me know if you have any issues!

Unfortunately, this does not work for me. I am running coder via the kubernetes helm chart. When i set VSCODE_PROXY_URI=https://your-url/proxy/{{port}}. The local address is still https://your-url/. I double checked that the env var is set in the coder container.

Hmm it seems to work as expected for me. Is the environment variable for sure set in code-server's environment?

Setup:

$ /tmp/code-server/bin/code-server --version 
4.20.0 d0215eca8804d0be5d3551c39404e336032c3141 with Code 1.85.1
$ VSCODE_PROXY_URI=https://your-url/proxy/{{port}} /tmp/code-server/bin/code-server

In code-server's terminal:

$ printenv VSCODE_PROXY_URI
https://your-url/proxy/{{port}}
$ python3 -m http.server 8000
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

And the result in the ports panel:

Thank you, i was setting the environment variable in my coder helm values. Instead i should have set it in the template within coder and now it works. I was trying to get port-forwarding without a wildcard cert to work, but currently it can only be done via subdomains. From the doc:

To enable port forwarding via the dashboard, Coder must be configured with a wildcard access URL.

@michaelkoelle
I am having the same issue. do you mind to share what you have to add in the template? thanks

@michaelkoelle I am having the same issue. do you mind to share what you have to add in the template? thanks

I edited the default kubernetes terraform template and added the env variable like this:

env {
    name  = "VSCODE_PROXY_URI"
    value = "https://your-url/proxy/{{port}}"
}

Code-server now has the correct link under the forwarded ports section. Unfortunately, coder does not know about this route and I could not access the container via the link.
