After having used many years of virtualization stacks (openvz, xen, vmware, kvm), I believe using docker on production is still quite tricky, if not very tricky. Especially for larger apps, at the very moment it's like juggling eggshells. It requires a great deal of orchestration as you gradually involve many docker instances and especially when the host is involved (volumes, links). So yeah , I wouldn't call it actual "containerizing" the app and it's more like containerizing "processes". I for one would love to see a day where openvz gets docker-like cli and having repository for creating/pushing/pulling images.
