Peru a repository synchronizer Some projects upstream bind together lot of files which might not be of interest, but still the convenience of a git pull to get latest updates, makes you to download the whole repository for just a bunch of files or folders. For example, this website uses Pelican to generate the webpages out of markdown files. Pelican does have a rich set of plugins but all of them are in the same folder in the git checkout. ...
Citellus: Detecting common pitfalls of deployments https://github.com/citellusorg/citellus Recording at https://www.youtube.com/watch?v=SDzzqrUdn5A What is Citellus? Citellus is a framework populated by community-contributed scripts that automate detecting problems, including configuration issues, conflicts with package versions, and more. History: how did was it started? The tool, started by Robin Černín after a long weekend shift checking one and over again several sosreports for the same data on different hosts. It started with some tests + shell wrapper, and was added a python wrapper by Pablo Iranzo to bring in more powerful features. ...
Why? While working on Citellus and Magui it soon became evident that Unit testing for validating the changes was a requirement. Initially, using a .travis.yml file contained in the repo and the free service provided by https://travis-ci.org we soon got https://github.com repo providing information about if the builds succeeded or not. When it was decided to move to https://gerrithub.io to work in a more similar way to what is being done in upstream, we improved on the code commenting (peer review), but we lost the ability to run the tests in an automated way until the change was merged into github. ...
Background Citellus allows to check a sosreport against known problems identified on the provided tests. This approach is easy to implement and easy to test but has limitations when a problem can span across several hosts and only the problem reveals itself when a general analysis is performed. Magui tries to solve that by running the analysis functions inside citellus across a set of sosreports, unifying the data obtained per citellus plugin. ...
Background Since I became Technical Account Manager for Cloud and later as Software Maintenance Engineer for OpenStack, I became officially part of Red Hat Support. We do usually diagnose issues based on data from the affected systems, sometimes from one system, and most of the times, from several at once. It might be controllers nodes for OpenStack, Computes running instances, IdM, etc In order to make it easier to grab the required information, we rely on sosreport. ...
