Systemd timer as a cron replacement

Thu, 29 Dec 2022 23:35:48 +0100

Instead of using a cronjob placed in our crontab, we can make use of a systemd timer on a modern linux system which is running systemd.

For a systemd timer to work, it needs two parts. One part consists of a .timer file, and a .service file.

The .timer file specifies when our service should be started. Just like a cronjob we can specify here on which days, in which week or at which time our service should be started. Our .service file contains all the details about the script or command we want to run.

Docker Install on Debian 10

Thu, 22 Apr 2021 13:49:41 +0100

In this guide we are going to install Docker on Debian 10 Buster. To be able to use Docker to its full extent, we also install docker-compose. There are two ways to install the Docker Engine, one with a regular apt install and one with an install script made by docker.

Install Docker from apt repo

First, we make sure to remove all versions of Docker. This is especially important if you have ever tried to install Docker on your Debian server before.
