On Friday one of the biggest content delivery network (CDN) had a configuration issue on its DNS, causing a global outrage for about half an hour. Hacker news has a long thread about it, but the embarrassing point is a lot of services was affected (Patreon, npmjs, DigitalOcean, Coinbase, Zendesk, Medium, GitLab…) including healthcheck 3-thrd part services (!)

Misterio: Ansible and Saltstack killer in docker

Misterio is a docker-compose based Ansible alternative.

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.

[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.

With t3a.nano instance you got 512MB at a very reasonable price per month (around $5 / 4.5€ for an on-demand instance). It should be enough for running a micro wordpress blog with docker, but sometime it is not. A pair of docker containers can eat up all the memory and your little box will be unable to launch docker-compose shutdown commands with out of memory error all way around. But we are here to solve the issue, and get the best bang for your bucks :)

Docker done right: docker compose and up to kompose

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.

In 1985, all my work started with a VIC-20 with 5Kb of RAM, and only 3583 bytes free for the BASIC. With 3 more kilobytes, VIC-20 would be able to unveil its more versatile graphic capabilities, but we have no luck. In 1995 I got a 8 MegaBytes computer with 512MB hard disk as workstation for my University Exams. I was a lucky boy, and that PC helped me to graduate up to 2000.

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 trust big providers? Email has legal value, and its content should stay as much as private as possible.
