Jerboa

Jerboa is a unikernel engine for building, running, and orchestrating VM-based application images.

It is built around two binaries:

• jerboa: CLI
• jerboad: Linux daemon

The current project state is best described as public beta:

• the core architecture is real and coherent
• the feature surface is already meaningful
• the operational matrix is still opinionated and not friction-free

Current Status

What exists today:

• image builds from static ELF binaries and source projects
• build drivers for go, node, python, rust, and raw
• VM execution on QEMU and Firecracker
• managed bridge networks with TAP-backed guests
• internal DNS
• volumes
• compose stacks
• replicated services
• daemon-side metrics, traces, stats, and dashboard
• Windows support through a dedicated WSL2 distro hosting the daemon

What this is not yet:

• a general-purpose Docker replacement
• a zero-friction cross-platform runtime
• a fully stable networking/runtime surface for all workloads

Platform Model

Jerboa runs in two supported modes:

• Linux host: jerboa talks to a native jerboad
• Windows host: jerboa.exe talks to jerboad running inside a dedicated WSL2 distro managed by jerboa daemon

Important:

• jerboad is Linux-only
• native VM execution depends on Linux virtualization support
• Windows support is WSL2-based, not a native Windows daemon port

Quick Start

Linux

sudo scripts/install.sh
jerboa status
jerboa build examples/hello --name hello --lang go
jerboa run hello:latest --attach

Windows

jerboa daemon install
jerboa daemon start
jerboa status
jerboa build examples/hello --name hello --lang go
jerboa run hello:latest --attach

Documentation

• Getting Started
• CLI Reference
• Compose
• Architecture
• Observability

The short version:

• port publishing requires --network
• TCP forwarding works today
• UDP mappings are accepted syntactically but are not forwarded yet
• the Windows path depends on WSL2
• the public surface is broader than the amount of battle-hardening so far

Repository Layout

• cmd/jerboa/ - CLI
• cmd/jerboad/ - daemon
• internal/vm/ - VM lifecycle and hypervisor backends
• internal/image/ - image store and build path
• internal/network/ - bridge, TAP, IPAM, and port forwarding
• internal/service/ - replicated services
• internal/compose/ - compose parser and ordering
• internal/wslboot/, internal/wsldistro/ - Windows/WSL support
• tests/integration/, tests/e2e/ - higher-level tests
• kernel/ - Nanos-derived kernel tree and tooling
