Optional arguments with getopt_long(3)

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.

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. CFEngines autonomous agents CFEngine works by installing and running an agent on every host of your infrastructure. It is distributed, each CFEngine agent will evaluate its policy periodically and independently.

cf-remote is now available via pip

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

To make it as easy as possible to get started with cf-remote and CFEngine, it is now available on pypi. Getting started Installing cf-remote is as easy as:

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.

How to implement CFEngine custom promise types in bash

To implement a custom promise type in CFEngine, you need a promise module. The module is an executable, and can be written in any language. It’s possible to write one from scratch, but to make it as easy as possible, we decided to provide libraries for common programming languages.

How to serve policy from a local git server

Several months ago I started the practice of using CFEngine Enterprise and its Mission Portal UI on a daily basis to manage the connected devices in my home. To start, I brought up an old desktop machine, cfengine-hub, to use as my hub and downloaded Enterprise, which is free for use up to 25 hosts. The next step in using best practices is to deploy policy from a version control repository.
