Running Docker containers on physical servers is the ideal scenario. Containers have less overhead than traditional virtualization (KVM, Vmware, Xen, etc) but generally cloud users are running their containers on VMs, adding back the overhead. Unfortunately that is the tradeoff for running containers in the cloud. However, there is another option with Rackspace OnMetal servers. OnMetal is a cloud instance that is launched in minutes and allows cloud users to leverage physical hardware for containerized applications. In this talk I’ll discuss some of the tradeoffs you’ll need to consider when using Rackspace OnMetal. We’ll also walk through deploying CoreOS and utilizing Fleet and Flannel. Finally we’ll talk about some architectural design ideas on leveraging Docker and OnMetal.
