GitHub - markamo/envpod-ce: Zero-trust governance environments for AI agents

EnvPod v0.1.15 — Zero-trust governance environments for AI agents Author: Mark Amo-Boateng, PhD · mark@envpod.dev Copyright 2026 Xtellix Inc.

Envpod is the zero-trust governance layer for AI agents.

Docker isolates environments. Envpod governs access to real ones.

AI agents are useful only when they can work with real local context: your code, files, tools, shell state, and workflows. But direct host access creates a broken trust model.

Docker forces a tradeoff: either the agent works in an isolated environment and loses real context, or you bind-mount the host and lose meaningful control. Envpod removes that tradeoff — agents work with your real environment through a copy-on-write layer, with review, rollback, audit, approval gates, secret isolation, and per-pod DNS governance.

Isolation is a wall. Governance is a policy. Docker was built for microservices. Envpod was built for agents.

Nothing touches the host until you review it.

$ envpod diff my-agent
M  .gitconfig
A  src/utils.py
A  src/helper.py
D  tests/old_test.py
A  node_modules/...  (47 files)

$ envpod commit my-agent src/ --rollback-rest
Committed 2 file(s). Rolled back 48.

Why Not Just Docker?

Because Docker gives you coarse isolation, not fine-grained governance.

With Docker, you usually end up in one of two modes:

1. Strong isolation, weak usefulness — the agent works in a separate environment, losing access to your real files, tools, and working context.
2. Strong access, weak control — you bind-mount the host so the agent can work on real files, but lose the review-and-commit model.

Envpod lets the agent work with real local context through a copy-on-write layer, while keeping changes reviewable and adding controls: audit, approval, secret isolation, and per-pod DNS policy. See Docker vs Envpod for a full comparison.

Features

COW Foundation — OverlayFS copy-on-write. Every write goes to a private overlay — the host is untouched. Review changes with diff, accept with commit, discard with rollback. The foundation makes everything else reversible.

Processor Wall — cgroups v2 (CPU, memory, PID limits), seccomp-BPF syscall filtering, CPU affinity. A runaway agent cannot starve the host.

Network Wall — Each pod gets its own network namespace with veth pairs. Embedded DNS resolver per pod with allowlist, denylist, or monitor modes. Every DNS query is logged.

Memory Wall — PID, mount, UTS, and user namespace separation. Processes in the pod cannot see or signal host processes.

Devices Wall — Selective GPU, display, and audio passthrough. Hardware access without escaping governance.

Credential Vault — Secrets stored encrypted (ChaCha20-Poly1305), injected as environment variables at runtime. Vault proxy injection (v0.2) goes further: a transparent HTTPS proxy intercepts API requests, strips dummy auth headers, and injects real credentials at the transport layer — the agent never has access to real API keys in env vars, memory, or config files.

Web Dashboard — Browser-based fleet management UI (envpod dashboard). Real-time pod overview with resource monitoring, audit trail viewer, filesystem diff inspector, and one-click commit/rollback/freeze/resume actions. Create, destroy, and clone pods from the browser. Session-token authenticated — blocks CSRF and local process attacks. See Dashboard Guide.

Action Queue — Actions classified by reversibility: immediate (COW-protected), delayed (auto-execute after timeout), staged (human approval required), blocked (denied).

Audit Trail — Append-only JSONL logs for every action. Static security analysis of pod configurations via envpod audit --security.

Monitoring Agent — Background policy engine polls resource usage and can autonomously freeze or restrict a pod based on configurable rules.

Remote Control — Freeze, resume, kill, or restrict a running pod in real time via envpod remote.

Live DNS Mutation — Update a pod's DNS allow/deny lists without restarting via envpod dns.

Undo Registry — Every executed action records its undo mechanism. envpod undo reverses any reversible action.

Display + Audio Forwarding — GPU passthrough, Wayland/X11 display forwarding, PipeWire/PulseAudio audio forwarding for GUI agents. Auto-install desktop environments (xfce, openbox, sway) via devices.desktop_env.

Web Display (noVNC) — Run a full browser desktop inside a pod, accessible from any browser at localhost:6080. Envpod auto-brands the interface, auto-connects (no click needed), and includes a file upload button (files go to /tmp/uploads/). Built-in audio streaming via PulseAudio + Opus/WebM with toast notifications for upload status. All supervisor processes auto-restart on crash. Works on headless servers, SSH sessions, no host display needed. Three desktop environments: xfce (~200MB), openbox (~50MB), sway (~150MB). Default ports: 6080 (display), 6081 (audio), 5080 (upload).

Snapshots — Save and restore the agent's overlay state at any point. envpod snapshot create/ls/restore/destroy/prune/promote. Auto-snapshot before every run. Promote any snapshot to a clonable base pod. Configurable retention.

Port Forwarding — Three scopes: ports (localhost only), public_ports (all interfaces), internal_ports (pod-to-pod only). State-tracked for exact cleanup. Live forwarding via -p/-P/-i flags at run time.

Pod Discovery — Pods find each other by name (agent-b.pods.local). Bilateral enforcement: both pods must opt in. Central envpod dns-daemon manages the registry. Live mutation via envpod discover.

Budget Enforcement — budget.max_duration auto-kills the pod after the configured time. Logs a budget_exceeded audit event.

Presets & Interactive Wizard — 18 built-in presets across 4 categories. envpod init my-agent launches an interactive wizard. --preset claude-code for non-interactive. Customize CPU, memory, GPU after selection.

Guardian Cgroup — Display, audio, and upload processes run in a guardian/ subcgroup that survives envpod lock/envpod unlock (cgroup freeze/thaw). The user's app runs in app/. Lock freezes the app but the desktop stays responsive.

Jailbreak Test — Built-in security boundary probe (examples/jailbreak-test.sh). Tests filesystem escape, PID namespace, network namespace, seccomp, cgroup limits, and information leakage. Three phases: host boundary, pod boundary, hardening. Runs as root and non-root.

Host App Auto-Mount — List apps in pod.yaml and envpod resolves binaries, shared libraries, and data directories via which + ldd, then bind-mounts them read-only. No reinstalling Chrome, Python, or Node inside every pod — instant, zero disk overhead.

Clone Host User — host_user: { clone_host: true } clones your username, shell, dotfiles, and workspace directories into the pod with COW isolation. The agent works in your real environment — your files, your tools, your config — but every change is staged for review. Sensitive paths (.ssh, .gnupg, .aws) excluded by default.

Mount Working Directory — filesystem: { mount_cwd: true } or envpod run -w mounts the current working directory into the pod with COW isolation. The agent sees your project files; writes go to the overlay. diff/commit/rollback as usual.

SDKs

Programmatic governance — manage pods, screen prompts, and orchestrate agents from Python or TypeScript.

Python: pip install envpod

from envpod import Pod, screen

with Pod("my-agent", config="pod.yaml") as pod:
    pod.run("python3 agent.py")
    pod.commit("src/", rollback_rest=True)
# auto: destroy + gc

result = screen("check this prompt")

TypeScript: npm install envpod

import { Pod, screen } from 'envpod';

await Pod.with('my-agent', { config: 'pod.yaml' }, async (pod) => {
    pod.run('python3 agent.py');
    pod.commit(['src/'], { rollbackRest: true });
});
// auto: destroy + gc

Auto-installs the envpod binary on first use. 44 methods with full CLI parity.

Performance

envpod vs Docker vs Podman (10 iterations, tests/benchmark-podman.sh)

Docker 29.2.1, Podman 4.9.3, envpod on Ubuntu 24.04, NVIDIA TITAN RTX x2:

• fresh = create from base + run + destroy (docker run --rm / podman run --rm / envpod clone+run+destroy)
• warm = run in existing instance (docker exec / podman exec / envpod run)

Envpod is faster at every operation while adding governance features neither Docker nor Podman have.

Core Benchmarks (50 iterations, tests/benchmark.sh)

*First run after init is ~1.3s (cold start: DNS resolver, cgroup init). Subsequent runs are 20-45ms.

Clone is ~10x faster than init — rootfs is symlinked (not copied), only cgroup + network namespace are recreated.

GPU Passthrough (NVIDIA TITAN RTX x2, 10 iterations, tests/benchmark-gpu.sh)

GPU passthrough is a zero-copy bind-mount of /dev/nvidia* and /dev/dri/* — no virtualization layer, no measurable overhead.

Disk Footprint (tests/benchmark-size.sh)

Docker 29.2.1, Podman 4.9.3, envpod on Ubuntu 24.04, NVIDIA TITAN RTX x2:

Base image / base pod (ubuntu 24.04):

Envpod base is 12% smaller than Docker. Docker/Podman copy the full distro userland into the image; envpod copies only /etc + apt state — /usr, /bin, /lib are bind-mounted from the host.

GPU image / base pod (CUDA 12.0 ubuntu 22.04):

Envpod GPU base is 69% smaller than Docker's CUDA image — CUDA libraries are bind-mounted from the host, not copied.

Per-instance overhead:

Clones share the base rootfs via symlink — near-zero per-clone overhead.

Scale Test (50 instances, tests/benchmark-scale.sh)

Docker 29.2.1, Podman 4.9.3, envpod on Ubuntu 24.04:

Envpod creation is 15x faster than Docker because envpod clone copies only a symlink + empty dirs (~1 KB per clone), while docker create allocates a full container layer. Envpod uses a two-phase destroy: envpod destroy is fast (deletes veth + netns, skips iptables), then envpod gc cleans up stale iptables rules in one batch. Dead rules are harmless — they reference non-existent interfaces. See Benchmarks for details.

Run the benchmarks yourself:

sudo ./tests/benchmark-podman.sh 10  # Docker + Podman + envpod comparison
sudo ./tests/benchmark-docker.sh 10  # Docker vs envpod only
sudo ./tests/benchmark.sh 50         # core benchmarks
sudo ./tests/benchmark-clone.sh 10   # clone vs init
sudo ./tests/benchmark-gpu.sh 10     # GPU passthrough (requires NVIDIA GPU)
sudo ./tests/benchmark-size.sh       # disk footprint comparison
sudo ./tests/benchmark-scale.sh 50   # scale test (create + run + destroy N)
