Today we are very happy to announce the release of CFEngine 3.13.0. This is a non-LTS release, introducing new features and functionality. There is a lot happening with CFEngine these days! This release is closely following last weeks release of CFEngine 3.10.5 LTS, and soon we will also release the next patch version of our 3.12 LTS series. So keep following our updates!
Contribute to CFEngine Did you know that CFEngine is a dual license open source project? And not only that, we are encouraging community contributions, and are always looking for ways to improve and grow our ecosystem.

How do you deal with config files that need different settings based on various services that are running on a host and cooperate with other teams? It’s a common question, and it came up on in #cfengine on libera.chat recently.
The issue is that team A might be working on package A, which requires some environment variables set. But team B might be working on a totally different thing – and want to achieve the same thing. I hoped to give them a bit of ’library’ code to take care of it, rather than have them touch a centralized environment-setting policy file.
Today we are very happy to announce the maintenance release of CFEngine 3.10.5. This is an update to the LTS 3.10 series, adding improved stability, several bug fixes and increased performance. 3.10 LTS is the successor of 3.7 LTS that, since August 2018, is no longer supported. We recommend everyone still using CFEngine 3.7 to upgrade to either 3.10 or 3.12. We are available to support you with such an upgrade if you need it. 3.10.5 LTS is a maintenance release (also known as a patch release), with the goal to increase the stability and reliability for CFEngine users and enable a safe upgrade path. As such, this release primarily includes bug fixes and low-risk changes that do not impact the compatibility between previous patch releases. Looking at the CFEngine release schedule, we can see that
At SURFsara we use CFEngine on our National Compute Cluster (LISA) and other systems as our configuration management tool. With the release of CFEngine 3.12 I want to highlight 2 new features, namely:
missing_ok multiple augments We use these 2 new features heavily in our framework in combination with my open source library cf_surfsara_lib. This library aims to be a central repository for configuring services, eg: ssh. For configuring the services we use JSON as data format and it is easily to override the default values via JSON. Pre CFEngine 3.12 there is only one strategy possible:
In some performance critical situations, it makes sense to limit management software to a single CPU (core). We can do this using systemd and cgroups. CFEngine already provides systemd units on relevant platforms, we just need to tweak them. I’m using CFEngine Enterprise 3.12 on CentOS 7, but the steps should be very similar on other platforms/versions. This post is based on an excellent article from Red Hat: https://access.redhat.com/solutions/1445073
Using ps to check what CPU core is utilized Listing all processes and their core We can use ps to check CPU core for desired processes:
Today we are happy to announce the general availability of CFEngine 3.12.0 LTS! This release has a lot of new features, and we are very excited about all the new possibilities you get with CFEngine 3.12.0 LTS. If you are using the previous LTS, 3.10 you will also benefit from all the new features, improvements and testing of the 3.11 release, which you can read more about in the CFEngine 3.11 release post.
Today we are happy to announce the general availability of CFEngine 3.12.0 LTS beta. The release of 3.12.0 beta took longer than expected. As a result we have decided to adjust our release schedule, and we releasing 3.12.0 beta now and later this year 3.12.0 will be the next official LTS release. If you are planning to contribute features or fixes to the next set of releases (we warmly welcome that !), we are always accepting those. The window for features is not closed for 3.12, but we appreciate help with fixing potential bugs in the beta, improving the performance if there are any identified issues, or generally implementations of suggestions moving forwards. If you want to start contributing but are unsure how? - Send documentation updates as pull requests to cfengine/documentation. - Search for issues labeled easy that are good candidates for new contributors to cfengine/core.

RPM packages now respect the chkconfig specified state when stopping a service. Now if the cfengine3 service is off for runlevel 2 the CFEngine services are stopped when you switch to runlevel 2. cf-monitord now correctly detects the usernames for processes on AIX. Classification when running under the Xen Hypervisor was also fixed. Masterfiles got fixes to the apt_get package module so that it works correctly when more than one source repository contains the package. Masterfiles also saw the addition of oslevel (on AIX), mailx (on Linux, Darwin, OpenBSD, NetBSD, and FreeBSD) to the paths bundle. The prunetree bundle was added to the standard library making it easier to recursively delete files and directories up to a specified depth older than a specified number of days. Enterprise gets bug fixes related to exporting reports and sharing host categorization views and reports. Additionally when hostnames are displayed in reports they now link to the individual host info page and usernames are now allowed to contain dots (.). Masterfiles now ensures the postrgres log file is rotated. The verbosity of some maintenance policy was increased and the policy to clear a build up of unreported data now includes previous_state and untracked reports. Some Enterprise dependencies were updated:
