    Hosting your own email server is not a mandatory task; it increase your attack surface too. But relaying too much on big emails provider (Gmail, Outlook, Aruba, Fastmail) could be a risk for our democracy. For instance, who decide how Spam is managed (i.e. what could be a Spam email)? Can we聽trust big providers? Email has legal value, and its content should stay as much as private as possible.

    Docker was born for the cloud. It is the easiest way to run different software in a tiny box, installing it in a rapid way and with a nice way to wipe it in a snap. But when docker shines are the little docker compose files, which realize the Infrastructure as Code, a configuration file which declare in an easy and simple way how services are connected.

    [UPDATED 21/3/2022]

    I have a shiny mail server on gioorgi.com. I decided to manage it on first person because it is important to have tight control on your email, in my humble opinion. It is not strictly necessary, but lending your email address to big company like Googles, Microsoft, Yahoo and so on could be a issue if you get banned by them for whenever reason.

    Misterio is a聽 docker-compose based Ansible alternative.Misterio rocks!
    https://github.com/daitangio/misterio

    Why

    I need to show Ansible and Saltstack configuration manager are nice tools but in a K8s world, the same result can be achieved in a much simpler way.
    It was to teach the container way to some co-worker.
    Without effort, I end up with a tool I am using on my home machines, which include a bunch of very different architecture (Ubuntu Boxes, ARMs RPi2, Windooze).
    So I think it would be nice show Misterio to the world...and yes there is a bit of magic, called containers.
