FreeBSD-Dockerbox

This project is still a work in progress.

This project aims to provide usage of docker on FreeBSD by installing and running dockerd inside a linux bhyve vm called dockerbox.

Project Structure

This repository (freebsd-docker) holds the core files to run a dockerbox service, including rc script and configs.

freebsd-dockerbox-debian is the repository for dockerbox's underlying disk images.

freebsd-dockerbox-port holds dockerbox's port related files.

Installation

To install from source, clone this repository and run make install.

# Install dockerbox script, config
make install

Download the dockerbox disk images.

make fetch-disk

Enable and start the dockerbox service.

service dockerbox enable
service dockerbox start

The make install command automatically detects the default gateway interface for connecting to the Internet. To modify it, edit ext_if specified in /usr/local/etc/dockerbox/dockerbox.conf

ext_if=ue0

Usage

Make sure you have docker installed and dockerbox's disk image downloaded.

pkg install docker

service dockerbox fetch

Also install tools like grub2-bhyve etc else you'll end up seeing error messages like pid 2859 (bhyve), jid 0, uid 0: exited on signal 6 (no core dump - other error) when you start dockerbox.

pkg install grub2-bhyve
pkg install e2fsprogs

Starting dockerbox

service dockerbox start

Export DOCKER_HOST.

export DOCKER_HOST=10.0.0.1:2375

Try out docker!

docker run hello-world

The ip address of dockerbox is currently fixed to 10.0.0.1

Stopping dockerbox

service dockerbox stop

Resize docker data storage.

dockerbox resize 1G

Currently only extending storage is supported.
