1 DOCKER & CONFIGURATIEMANAGEMENT Docker Meetup

2 EVEN VOORSTELLEN RIK - In dienst sinds 2012 bij Oxilion - Drones - Voetballiefhebber - Verzot op techniek

3 INHOUD Configuratie-management? Continuous Integration mogelijkheden Gitlab CI Travis-CI Voorbeeld op basis van Ansible Voorbeeld op basis van Puppet

4 CONFIGURATIEMANAGEMENT? Configuration management (CM) is a systems engineering process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.

5 CONFIGURATIEMANAGEMENT & OXILION Bij Oxilion wordt configuratiemanagement toegepast op alle door ons beheerde servers middels Puppet. We gebruiken peer-review en continuous integration om zorg te dragen dat alle wijzigingen juist zijn.
