Configuration

These configuration have been tested only on FreeBSD 12.1-RELEASE.

1. Introduction

Wait… what? FreeBSD does not have Docker! Doesn’t it?

Well of course not really, but you can still install Docker using FreeBSD, it won’t just be FreeBSD in Docker since FreeBSD is not supported as Docker images.

In this blog post, I won’t discuss exactly how to install a few things, I will mostly point to blog posts and documentations so that you know what to do to install Docker and Kubernetes using FreeBSD.

These configuration have been tested only on FreeBSD 12.0-RELEASE.

Description

I’ve been trying for almost half a day to gather informations around about FreeBSD Jails using the VNET/VIMAGE, and since the only informations about this subject are only in /usr/share/examples/jails. It seems there are 2 choices when considering the VNET jail approach:

• using netgraph with the ngctl utility, and the jng helper in /usr/share/examples/jails
• using bridges and epair interfaces to bridge networks over the public interface, and so to use jib in the same folder

Since I don’t know anything about netgraph, I’ve prefered to take time and put the correct configurations on the host and the jail for bridge/epair.

Earlier this year, I decided not to throw as much money in some dedicated online server (dedicated racked server) from Online.net. Not that the service would have been horrible, but with my current budget I could not offer myself such a high level service anymore.

So and since I had already tested DO (DigitalOcean) VPS (Droplets), I had migrated my mail server there. It was a simple 40GB / 2GB / 2CPU VPS with ZFS installed until recently, so with just one disk.
