LandJail

Note

Agent Firewall requires the AI Governance Add-On. As of Coder v2.32, deployments without the add-on will not be able to access Agent Firewall.

landjail is Agent Firewall's alternative jail type that uses Landlock V4 for network isolation.

Overview

Agent Firewall uses Landlock V4 to enforce network restrictions:

All bind syscalls are forbidden
All connect syscalls are forbidden except to the port that is used by http proxy

This provides network isolation without requiring network namespace capabilities or special Docker permissions.
