INHOUD

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

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.

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.

• Bamboo• Drone.io• Gitlab Ci• GoCD• Jenkins.io• Travis-CI

CONTINUOUS INTEGRATION MOGELIJKHEDEN

• Autoscaling • Volledig geïntegreerd met Gitlab• Realtime logging• Geschreven in GO• Continuous Delivery mogelijkheden

Gitlab CI

• Open-source sinds 2011• Gratis voor open-source projecten• Fantastische integratie met Github• Bewaar je configuratie bij je code• Ondersteuning voor diverse talen en frameworks

waaronder Xcode en Android
