Our beloved cfbs CLI tool for working with CFEngine Build is rapidly evolving. At the time of writing, we are currently at version 3.2.1. Thus I would like to take this opportunity to talk a bit about the latest and greatest features; including support for users to manipulate input parameters in modules, as well as a couple of new build steps.
If you haven’t yet got a hold of the latest version of cfbs, you can update it with pip using the following command:
Did you know that nightly builds of CFEngine are available?
cf-remote is the most convenient way to get nightly packages. If you’re not familiar with it, or if you need a refresher, check out our other blog posts about cf-remote.
Listing packages By default cf-remote list will emit a list of available releases and the URLs for the newest CFEngine Enterprise LTS release.

This guide is designed for the novice user of CFEngine who wishes to explore the power of Emacs while developing CFEngine policy files – and will introduce the use of some Emacs features and plugins along the way.
There are two types of editors available in the Unix and Linux world: line and visual. Examples of line editors are ed and sed. These allow you to edit a file one line at a time.
A while back we released version 2 of cfbs, and even though we release versions of this tool quite frequently, without announcing it on the blog, we thought this was a good opportunity to talk a bit about the tool, what’s new and our direction with it in the future. The reason why we called this the “2.0” release is that we are trying to follow semantic versioning, and there were some big new features in the release which could be considered breaking changes.

CFEngine and Ansible are two complementary infrastructure management tools. Findings from our analysis show that they can be combined and used side by side with joint forces to handle all areas in the best possible way. Part of infrastructure management is hosts deployment, either when building a brand new infrastructure or when growing one by adding new hosts. This is something Ansible truly excels in as it makes it very easy to run a sequence of steps on all hosts to initialize (deploy) them and it only requires SSH access to the hosts and Python installed on them. 1
With the recent release of build.cfengine.com and cfbs I have been thinking about the process of converting a traditionally manged policy set. I consider a traditionally manged policy set one where you have a repo with the root of masterfiles being the root of the repository, or even having no repository at all and managing masterfiles by editing directly in the distribution point (e.g. /var/cfengine/masterfiles). Before jumping in with both feet and converting to a cfbs managed policy set you might want a hybrid situation where you can leverage some of the benefits of cfbs but without making drastic changes to the way policy is currently managed. That’s what this post is about, using cfbs with your traditionally manged policy set. Note: This post assumes that you already have cfbs installed and understand the basics of how it works. Check out our previous blog posts if you want to review how to get started with cfbs.
How can I work with secrets using CFEngine?
Craig (Digger) demoed cf-secret and how he uses it for protecting secrets used to mount LUKS encrypted drives.
