Current Behavior

Problem Description

I'm currently running Coder in a Docker container usingnetwork_mode: "host" which works perfectly, but I need to avoid using host networking mode for security and isolation reasons. When I remove the host network mode, the container doesn't function properly.

Current Working Configuration

version:'3.8'services:coder:image:ghcr.io/coder/coder:latestcontainer_name:codernetwork_mode:"host"# This works but I want to avoid itvolumes:      -coder_data:/home/coder      -/var/run/docker.sock:/var/run/docker.sockrestart:unless-stoppedvolumes:coder_data:

What I've Tried

I attempted to replacenetwork_mode: "host" with explicit port mapping:

ports:  -"7080:7080"environment:  -CODER_HTTP_ADDRESS=0.0.0.0:7080

However, this doesn't provide the same functionality as the host network mode.

Expected Behavior

I expect Coder to work with standard Docker networking (bridge mode) using explicit port mappings, providing the same functionality asnetwork_mode: "host" but with better container isolation.

Additional Context

From thecoder ping output, I can see the service is running on port 7080, but I suspect there might be additional networking requirements for workspace communication or other Coder features.

Any guidance on the proper network configuration would be greatly appreciated!

Relevant Log Output

Steps to Reproduce

1. What is the recommended Docker Compose configuration for Coder without usingnetwork_mode: "host"?
2. Are there specific ports or network requirements that need to be configured?
3. Do I need additional environment variables for proper network configuration?
4. How should I handle dynamic port allocation for workspaces in this setup?

Environment

• Coder Version: Latest (from ghcr.io/coder/coder:latest)
• Docker Compose Version: 3.8
• Host OS: proxmox
• Network Setup: Private network with WireGuard VPN
