AWS created Control Tower as a way to allow organization to manage their AWS Organization, accounts and their setup. Control Tower has nice UI in AWS console, but if you try to terraform anything you will quickly get confused, because terraform (with AWS provider 5.62.0) has ONLY TWO aws_control_tower_* resources. Situation with awscli (version 2.17.5) isn&rsquo;t much better.https://ylitalot.com/about/Sun, 11 Dec 2022 12:00:00 +0200https://ylitalot.com/about/Who?

Python has nice test framework called doctest, which allows you to insert unit test cases as comments in your python code. My current tests are done for methods that don&rsquo;t recover mockups (for things like file system access) and simply return strings, lists and such to caller. In following example, I have method called _extract_from_markdown, which gets one line of text from markdown file as string.https://ylitalot.com/posts/chef-notes/Mon, 14 Sep 2015 12:00:00 +0200https://ylitalot.com/posts/chef-notes/<p>Random notes about chef configuration management tool and related topics.</p>https://ylitalot.com/posts/iptables-notes/Mon, 14 Sep 2015 12:00:00 +0200https://ylitalot.com/posts/iptables-notes/<p>Random notes about iptables, ufw and such tools in Linux.</p>https://ylitalot.com/posts/puppet-notes/Mon, 14 Sep 2015 12:00:00 +0200https://ylitalot.com/posts/puppet-notes/Random notes about puppet configuration management tool and related topics. Puppet doesn&rsquo;t like symlinks Link to heading When you start building /etc/puppet/environments/production in your puppet master, don&rsquo;t use symlinks on directory tree. I once made the mistake of using symlinks for manifests and modules directories and was getting frustrated, when puppet agent didn&rsquo;t seem to get my manifests/site.pp file. Once I copied all the directly into /etc/puppet/environments/production tree, things started to work.https://ylitalot.com/posts/virtualboxes-notes/Mon, 14 Sep 2015 12:00:00 +0200https://ylitalot.com/posts/virtualboxes-notes/<p>Random notes about VirtualBox and related topics.</p>
