Practical API case: CSV compliance extraction

Introduction Hello folks! Today, I’m writing this post to talk about a solution we found to the following problem: how do you export compliance data from a Rudder installation? The use case was: how do you export Rudder compliance metrics that are currently accessible in the Web UI in a machine-usable format so you can […] Read more

Discover the new package management implementation in Rudder

Rudder 3.2, starting from 3.2.8, offers a new package management implementation. It is new, and not as tested as the previous one, but already usable. This article explains the reason for this change, and will give an overview of the features and their usage. Why? As you may have noticed, the current package management implementation […] Read more

Manage Jenkins with ncf

Jenkins is an excellent application to automatically build/test software projects. We rely on it in Normation to build, test and package Rudder and ncf, for all the OSes and versions we support; resulting in a lot of jobs to manage (currently over 300). Part of Jenkins’ awesomeness is that it has a neat REST API, […] Read more

Rudder presentation at FOSDEM

We’ve been back from the latest FOSDEM in Brussels for a week now, but are only just recovering from the freezing-cold weather they had there… As always, FOSDEM was a great event, with thousands of open source users, contributors and developers all mixing together and sharing their findings, software and thoughts. A real spirit of […] Read more

CFEngine 3 is a very secure tool, that relies on keys to identify hosts and authorize connections. To set up a secure CFEngine infrastructure, you ought to exchange keys between hosts (note that if you don’t have confidential data […] Read more

Configuration management tools for cloud computing (Open World Forum 2011)

The Open World Forum 2011 edition took place last week in Paris. I was invited to present a workshop in the Cloud Computing track. This gave me the opportunity to outline the importance of optimizing the “setup” phase of machines when using cloud computing. Today’s tools and APIs make it very easy to create and […] Read more

Cfengine 3.1.5 is nearly out, what can we expect from it?

Here at Normation, we use Cfengine 3 extensively for configuration management across Linux and Windows servers. Cfengine 3 is an open source project, and as every good open source project, the trunk version is always available (but not always very reliable) and stable versions are released regularly. Prior to the release of a new version, […] Read more

Why we use Cfengine: file editing

Here at Normation, we use Cfengine 3 extensively for configuration management across Linux and Windows servers. A question we get often is why Cfengine? I’d like to focus this post on file editing. Since Configuration Management has a lot to do with configuration files, file editing (either from a template, or just setting parameters) is […] Read more

Cfengine tip: Keeping cf-execd alive (whatever happens)

As good as your configuration management tool may be, it can only do it’s job if it’s running. Some tips on making sure this is the case, whatever happens. Why just cf-execd? With Cfengine, the “heavy lifting” is done by cf-agent, which is normally run on a regular interval by cf-execd (a daemon that runs […] Read more

Why we use Cfengine: memory footprint

Here at Normation, we use Cfengine 3 extensively for configuration management across Linux and Windows servers. A question we get often is why Cfengine? This is phrased either as What is so great about Cfengine? or What is the difference between Cfengine and Puppet or Chef? (as a reminder of how these 3 projects are […] Read more
