CFEngine 3.19 released - Collaboration

Today, we are pleased to announce the release of CFEngine 3.19.0! In 2021, for this release, and the launch of CFEngine Build, our focus has been on collaboration.

Cloning git repos and creating systemd services with CFEngine

Using modules, you can add custom promise types to CFEngine, to manage new resources. In this blog post, I’d like to introduce some of the first official modules, namely git and systemd promise types. They were both written by Fabio Tranchitella, who normally works on our other product, Mender.io. He decided to learn some CFEngine and within a couple of weeks he’s contributed 3 modules, showing just how easy it is to implement new promise types.
