CFEngine and Ansible are two complementary infrastructure management tools that both work with so-called inventories. However, the common term can be quite confusing because the way they are defined and created is very different for an Ansible Inventory and for a CFEngine Inventory. In the most basic case, an Ansible Inventory is just a file with a list of hosts and groups of hosts that Ansible then manages when fed the inventory file. On the other hand, CFEngine Inventory is a database of information about all the hosts in the infrastructure managed by CFEngine which the hosts themselves report. In a more complex scenario, an Ansible Inventory can also contain a lot of information about the hosts in the infrastructure, but those need to be pulled from somewhere else and given to Ansible. With CFEngine, hosts talk to a CFEngine Hub, pull policy from it and report information back to it. On the other hand, with Ansible, policy is pushed to the hosts from one place which thus must have a list of all hosts available in advance, potentially with some extra information (parameters) of the hosts.

Manually managing groups on a large infrastructure can be a tedious task, and is therefore best suited through automation software like CFEngine. Unfortunately - at time of writing - CFEngine does not have any built-in promise types for managing groups. But fear not; in CFEngine 3.17, custom promise types were introduced. This new exhilarating feature does not only allow for members of our community to make their own custom promise types, but also lets the CFEngine Core developers prototype new future promise types. In this blog post, I’d like to introduce one of our prototypes; the experimental groups promise type.
Come see what’s new in CFEngine policy management!
Herman (Product Manager) introduces and demonstrates new tooling, the CFEngine Build System (cfbs). cfbs is a command line tool to facilitate policy management and consuming modules written by others.

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. Thanks, Fabio!
I recently had a minor task involving changing an option - on one of our command line tools - from taking a required argument, to taking an optional argument. This should be easy they said; just change the respective option struct to take an optional argument, add a colon to the optstring, and get on with your life.
Well, it proved to be easier said than done. My initial expectation was that a solution similar to the one below should just work. And it does work, just not in the way I expected.
Come see the new hotness in the latest LTS series, 3.18!

Today, we are pleased to announce the release of CFEngine 3.18.0! The focus of this new version has been extensibility. It also marks an important event, the beginning of the 3.18 LTS series, which will be supported for 3 years.
Several new features have been added since the release of CFEngine 3.15 LTS, in the form of non-LTS releases. In this blog post we’ll primarily focus on what is new in 3.18, but we will also highlight some things released in 3.16 and 3.17.
In the past 2 and half months, we have refreshed the visual design of the CFEngine UI (Mission Portal). As part of the UX/UI design team, our goal is to provide an up-to-date design as well as an easy-to-use user interface. In this blog post, I will showcase the changes we made, the process behind the redesign, and the challenges encountered along the way. I am sharing the journey with you and hope to inspire the people who are currently planning to take a similar path.
