Operating system

Description

Usecase
Create custom docker image with reverse proxy(e.g caddy) on port 8080 using dockurr/windows as a base image to forward traffic to noVNC client running on 8006.

Sample Dockerfile

FROM dockurr/windows:latest
WORKDIR /

# Set environment variables
ENV VERSION="win11"
ENV CADDY_VERSION=2.7.6


# Download and install Caddy
RUN curl -L https://github.com/caddyserver/caddy/releases/download/v"$CADDY_VERSION"/caddy_"$CADDY_VERSION"_linux_amd64.tar.gz -o caddy_"$CADDY_VERSION"_linux_amd64.tar.gz && \
   mkdir caddy-download-"$CADDY_VERSION" && tar -xvf caddy_"$CADDY_VERSION"_linux_amd64.tar.gz -C ./caddy-download-"$CADDY_VERSION" && \
   mv ./caddy-download-"$CADDY_VERSION"/caddy /usr/local/bin/

# Copy files
COPY Caddyfile /Caddyfile
COPY entrypoint.sh /entrypoint.sh

# Ensure entrypoint.sh is executable
RUN chmod +x /entrypoint.sh

EXPOSE 8006 3389 5900 8080

# Set the entrypoint
ENTRYPOINT [ "/entrypoint.sh" ]

** Entrypoint.sh**

`#!/bin/sh

# Start Caddy server to reverse-proxy noVNC to port 8080

caddy start -c /Caddyfile --pidfile /var/caddy.pid

`

** Caddyfile**

`:8080

route *  {
	reverse_proxy 127.0.0.1:8006
}


`

Command Used to Build Docker Image
docker build -t windows-vnc-vm . && docker run -p 8006:8006 -p 5900:5900 -p 8080:8080 --device=/dev/kvm --device=/dev/net/tun --cap-add NET_ADMIN --stop-timeout 120 windows-vnc-vm

Expected Result
Once windows VM is up and running, we should be able to connect to VM using webclient (no-vnc) on port 8080

Current Result
Once VM is downloaded and started but its not able to run on 8080 , its only running on 8006.
