KasmVNC in coder not working with my personalized template

Hi, First, good job on coder, it is a very nice tool. About the error. I have coder installed in a Kubernetes cluster k3s with traefik. Using this template https://github.com/sharkymark/v2-templates/tree/main/src/pod-idea-vnc I access correctly the VNC client trough the browser. Now I want to use my own template with Kasmvnc or noVNC installed (prefer KasmVNC). Both templates are working in docker client with port forward, however they do not work on coder. I have this message that I attached. To be honest I am not a specialist, so I do not know If there is more logs to have a look into to debbug my issue Do you have any idea of things that I can try? Thanks

@bruno-laranjo how are you installing KasmVNC?

bruno-laranjoOP•2mo ago

With your help @深雪 I get what is going on. @Phorcys I have kasmVNC installed from the RPM installer available on their website. The issue is the correct way to run KasmVNC with the "default" way of installing it is, on the template file, for the "coder_app" use the subdomain=true. I cannot set subdomain=true because of my networks requirements. I just need a way to config KasmVNC with subdomain=false

bruno-laranjoOP•2mo ago

With the info I have I managed to put working noVNC with coder For the container I built it based on this example https://github.com/coder/enterprise-images/blob/main/deprecated/vnc/Dockerfile.ubuntu Now I need to understand how to get KasmVNC container working.

@bruno-laranjo we have a KasmVNC module in the works that should be released very soon I would advise you to wait and use our module when it comes out

bruno-laranjoOP•2mo ago

Ok I will wait it them. Thank you for the support.

If you are eager to try, you can test it by adding

module "kasmvnc" {
  source   = "git::https://github.com/coder/modules.git//kasmvnc?ref=kasmVNC"
  agent_id = coder_agent.dev.id
  desktop_environment = "REPLACE with your desktop environment name" # i.e. lxde, xfce, gnome, kde, lxqt
}

module "kasmvnc" {
  source   = "git::https://github.com/coder/modules.git//kasmvnc?ref=kasmVNC"
  agent_id = coder_agent.dev.id
  desktop_environment = "REPLACE with your desktop environment name" # i.e. lxde, xfce, gnome, kde, lxqt
}

Replace dev with your coder_agent resource name. Please share any feedback you have and if it works for you. Currently we require the workspace to have a desktop emnvironment already installed.

Thanks, I will try and give feedback Hi @Atif , so I tested the module and do not work on my case. My network configuration does not allow me to have the subdomain = true option But I am happy with noVNC for now. Thank you all for your help. This tread can be closed.

Atif•2mo ago

There would be probably a way to run this without a subdomain but I haven't explored that out. Happy that hear that you were able to use noVNC.
