Problem to solve When working on the new Federated Reporting feature for CFEngine we had to solve the problem of collecting data from multiple CFEngine hubs (feeders) on a single hub (superhub). CFEngine hubs are using PostgreSQL to store data, so, more specifically, the problem was how to collect data from multiple PostgreSQL databases in one PostgreSQL database. And because we are talking about ~1 GiB of SQL data per feeder hub and for example 10 feeders connected to a superhub here, the initial and trivial solution using basically this ETL (Extract Transform Load) pipeline - pg_dump | gz | ssh | gunzip | psql - provided really poor performance.
Today we are happy to announce the general availability of CFEngine 3.15.0 beta. CFEngine 3.15 is our upcoming LTS (Long Term Support) release. The main focus of this release has been the new Federated Reporting feature. It also contains a lot of performance work and stability improvements. You can download CFEngine 3.15 LTS beta here.
Beta program CFEngine 3.15 is a beta release that is not generally supported, however, the quality is good and interesting new features are available.
On [2019-07-29 Mon] we released new builds of our Enterprise Hub packages for 3.12.2 and 3.14.0. This release addresses CVE-2019-10164.
PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow. Any authenticated user can overflow a stack-based buffer by changing the user’s own password to a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system account.
CFEngine Enterprise LTS versions 3.
Today we are very proud and happy to launch our latest non-supported release, CFEngine 3.14.0. 3.14 is a great number, being the closest we will get to π, we also wanted to introduce something very special this time around, and we did!
New features Let’s start with an overview of some new changes debuting in CFEngine 3.14.
Improved Role Based Access Control (RBAC) In CFEngine 3.14 we have introduced a new backend for managing RBAC settings, as well as a whole new UI in the Mission Portal to manage this.
We are happy to release the 2nd update to the CFEngine 3.12 LTS series. This update comes with many important stability and performance improvements and is thus well worth the upgrade from an older version of 3.12 LTS. CFEngine 3.12 LTS brings a lot of innovation, new features and improved performance to CFEngine, and allows you to make the most efficient use of your time. We are looking forward to your feedback on this release.
We are now happy to release the 6th update to the CFEngine 3.10 LTS series. This update comes with many important stability and performance improvements and is thus well worth the upgrade from an older version of 3.10 LTS. Looking at the CFEngine release schedule, we can see that CFEngine 3.10 LTS is maintained and supported until December 27th, 2019.That is the end of this year, so you should start planning on upgrading to CFEngine 3.
About a year ago, I wrote a small python script to automate installing and bootstrapping CFEngine on virtual machines in AWS. It had some hard coded IP addresses that I needed to update when I spawned new hosts, but other than that, it worked well. During manual testing, it saved me a lot of time instead of having to do things manually. Deploying CFEngine normally consists of these steps:
Determine what CFEngine package to use.
cf-runagent is a component for triggering remote agent runs using the CFEngine network protocol. It does not allow for arbitrary commands to be executed, but rather asks the remote host to run the policy it already has. To trigger cf-runagent from other systems or web interfaces, you want to be able to run it as non-root.
Install and bootstrap I will use cf-remote to set up a demo hub running CFEngine Enterprise 3.
CFEngine 3.12.1 LTS has now been released. This release brings many stability and performance improvements to the 3.12 LTS series. It is a stable and well-tested version of CFEngine. We wish to extend a big thanks to the ecosystem that helps make CFEngine great by reporting bugs, contributing fixes and suggesting new and improved functionality. Without you, CFEngine would not be the powerful, high performance, widely used product we all appreciate today!
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!
