The environment work fine on Linux and MacOS. But we needed to make this environment work also on Windows. Easy, right? Vagrant and Virtualbox are supposed to abstract all […]

With default settings Foreman does not allow Puppet Agents to specify their own environment when connecting to the Puppetserver. This makes it impossible to use r10k and feature branch workflow like you can with a normal Puppetserver. This behavior can fortunately be reverted easily by modifying Foreman configuration file, /etc/foreman/settings.yaml: # Allow testing feature branches […]

Reprovisioning bare metal Linux servers with Foreman and IPMI

The goal was to check if our automated "force-join to FreeIPA domain after reprovisioning" logic worked as intented. We did not have access to any graphical IPMI console, nor Foreman's GUI, so we had to do everything from […]

Määriteltyjen resurssien luonti suoraan Puppet-luokista

Jotkin Puppet ENC:t (External Node Classifier), hyvänä esimerkkinä Foreman, eivät tue määriteltyjen resurssien (Defined Resource Types) käyttöä suoraan, vaan kaikki konfiguraatiot pitää sisällyttää Puppet-luokkiin. Myös Hieran kanssa määritellyt resurssit ovat hieman ongelmallisia, koska ne pitää erikseen luoda create_resources funktiolla. Eräs ratkaisu on määrittää kaikki create_resources -funktiot site.pp-tiedostossa (sovellettu täältä): create_resources('mysqldump::backup',hiera('mysqldump_backups', {})) Tämän lähestymistavan ongelma on […]
