I am not familiar with matomo, but aren't those instructions enough? You go to DO, create new droplet from that image, and done? I assume once you have it installed you will get more info on how to add the tracker on your site from their interface ?

Matomo needs a database server (MySQL) and a way to execute cronjobs - that’s about it. There’s some gotchas if you’re running in a HA setup or if the database runs on a separate server.

I have a full deployment of Matomo in Kubernetes on gitlab [1] if anyone would find it useful (includes correct settings for running in multiple pods).

I haven't used the docker image, but Matomo is PHP in its simplest form.

You unzip it. Click through a setup wizard. Done.

(I also run in readonly noexec in an fpm chroot but that's not necessary.) I set it up for a couple of clients since the Piwik days and it's been pretty much set and forget, apart from the occasional upgrades.

There are plenty of advanced functionality which probably few people understand and use. For my personal projects I am fine with log analytics which I mostly use goaccess for.

Sorry for misleading you. You don't need docker to run matomo (docker makes it convenient to install matomo - especially if you are running other containers on your server - but there are shortcomings, mainly the container setup).

Matomo is just a set of php files. Upload them to any php hosting with a mysql database, in a matomo or matomoanalytics folder and point your browser to your domain name/matomo/ and the install setup should begin.

If you have 0 experience with docker and just needs matomo then forget about docker and start from the php file with a standard php/mysql host.
