reefy-dev-ubuntu

Ubuntu 24.04 with systemd as PID 1, packaged for use as a development environment container.

The base image for the dev-ubuntu app on Reefy - turn your home server into a Reef.

What's in the image

• ubuntu:24.04 base
• systemd + systemd-sysv so the container behaves like a Linux host (unit-managed services, journald, cron, sshd, udev, ...)
• Container-friendly pruning of default systemd units that don't make sense in a container (initctl, plymouth, conflicting udev sockets, most multi-user.target.wants/*, ...)

Build/dev dependencies (gcc, qemu, parted, mtools, ...) are NOT baked in - they live in the consuming project's setup script so this image rebuilds rarely.

Runtime requirements

systemd-as-PID-1 needs cgroup access + tmpfs for /run and /tmp:

docker run -d \
  --privileged \
  -v /sys/fs/cgroup:/sys/fs/cgroup:rw \
  --tmpfs /run --tmpfs /tmp:exec,mode=1777 \
  ghcr.io/reefyai/reefy-dev-ubuntu:24.04

Reefy app spec

The catalog spec for the Reefy dev-ubuntu app lives under reefy/app.json. It wires the runtime requirements above plus KVM passthrough, host /dev mount, and a /build volume for non-backed-up build artifacts.
