We thought we would mix things up a bit here and highlight our open source C library: libntech. I wanted to use libntech’s JSON code to write a minimal tool to parse, check and query JSON data. Using the various library functions related to files, json, strings, sequences and regexes helps …
When using CFEngine with the Masterfiles Policy Framework there are two standard “stages” involved in periodic maintenance: update the policy (update.cf) and evaluated the policy (promises.cf). In a standard install the cf-execd component periodically runs first the update policy and …
We here at CFEngine have seen the collaboration possibilities with Ansible for a long time. See our many ansible related blog posts including previously where I discussed our promise-type-ansible module which enables you to run ansible playbooks from CFEngine policy.

The MPF or Masterfiles Policy Framework is intended to provide a stable base policy for installations and upgrades, and is used by both CFEngine Enterprise and CFEngine community. When you create a new cfbs project with cfbs init one of the questions is related to the MPF: Do you wish to build on …

Recently we had a Fireside Chat with long-time contributor and CFEngine Champion Bas Van der Vlies. During that talk he mentioned a Build module he developed: promise-type-docker-compose. For this month’s Module Monday post I thought I would take this promise type for a spin alongside the …
Over three years ago we introduced git and systemd custom promise types. While these are quite functional I recently needed to manage a git repository that was private and so needed a way to authenticate to a git server, in this case gitlab. Gitlab has project access tokens but we didn’t …
I promised more Build modules in my previous monthly Monday module blog post: package-method-winget. And here they are: windows-capability and windows-optional-feature. Inventory Both of these modules use similar usage details to control whether to inventory and to promise the state for specific …
