Comparing Ansible and CFEngine

Generally speaking, CFEngine and Ansible can be used to solve the same problems, but their approaches are different. In this blog post I’d like to discuss the different approaches, their consequences, some advantages of each tool, and even using them together.

cf-remote is now available via pip

cf-remote is a tool for downloading and installing/deploying CFEngine.

Introducing GitHub Discussions for CFEngine

We are excited to announce that CFEngine is now using GitHub Discussions . GitHub Discussions is a feature of GitHub repos, and similar to Q&A platforms like Stack Overflow, and other online forums. After testing it out for a few weeks we are pleased with how it works and want to encourage all our users to try it. We hope this fuels more discussion and sharing among CFEngine users - it is easy to discover on GitHub, many of you already have GitHub users, the UI is nice, and so the barrier to entry should be very low.

Introducing CFEngine Custom Promise Types

In CFEngine 3.17 , custom promise types were introduced. This allows you to extend policy language, managing resources which don’t have built in promise types. The implementation of custom promise types is open source, and available in both CFEngine Enterprise and CFEngine Community. To implement a new custom promise type, you need a promise module. (The promise type is what you use in policy language (the concept), while the module is the underlying implementation - can be a python script, compiled executable or similar).
