Welcome to the first part of a multipart series that will detail getting Home Assistant running in Docker on your RaspberryPi. We’ll be installing Docker on an Ubuntu server instance running on Raspberry Pi. It will expose the services it runs through an instance of Traefik - that will automatically configure SSL certificates and it will give you a management interface called Portainer so that you can directly control the services running.

I’ve been running a RocketChat instance on my Dokku server for a while now and recently I went to upgrade it from the 0.7x release I was running to a more recent 1.2.x version. This post detail how hard that actually ended up being.

This was the year I took some time out to rebuild this site. As is typical for the personal projects we take on it featured large amounts of scope creep, a non-existant deadline and too many new technologies to learn.

One of things I’ve been playing with of late is a Docker container orchestration system called Rancher. I’ve been very excited to discover the features and capabilities the developers have created and despite being quite new it’s extremely well polished - for the most part it just works.

One of the projects they’d developed alongside their software is an operating system called RancherOS. It’s a light weight linux installation that runs it’s userspace entirely from within containers; the init process is docker itself. This allows the systems to run with very low overhead once booted and devote as much of their resources to the serving of your containers as is possible.

I’ve recently started to refactor my server configuration¹. It’s always been built with Ansible but it was one of the first things I ever did using that and I was fairly certain that every way I could have been doing it wrong I was.
