Foreman plays a central role in today's open source datacenter infrastructure. Although the webinterface is nice and the Hammer CLI is useful for basic scripting in order to build complete deployment pipelines, you want all your infrastructure as code. This is what foreman_provision is about. This talk will detail the rational behind foreman_provision and will showcase how it might fill gaps in your fully automated infrastructure provisioning. About Nils Domrose Nils works for Germany based inovex GmbH as a senior linux systems engineer and system architect. He designs and implements opensource software defined datacenter solutions. During the last 15 years Nils worked as a systems engineer and software developer for various ISP and Telco companies and designed and deployed several large scale, multi national services.
