It's been a few years since I've worked with bare metal, but doesn't Docker require a hypervisor for the containers?
You could swap to KVM or Hyper-V, but transitioning an org's hypervisor on bare metal is a massive task any way you cut it.
- zekrioca 4y agoCurrently, Docker only requires an hypervisor if you set it on Windows or MacOS.

- electroly 4y agoNo, docker doesn't require a hypervisor of any kind.
- yjftsjthsd-h 4y agoNo, Docker is not a hypervisor and doesn't use one unless you need to add one for security reasons; it uses Linux features to build containers. On the other hand, yes switching from virtual machines to containers it is likely to be a non-trivial workflow change and not something a company can do on a dime.
- jordanbeiber 4y agoNo hypervisor for cgroups (docker & friends), no. Which is why something like LXD/LXC outperforms hypervisor virtualization by quite a bit. I was on a team that ran performance critical stuff for a reasonable sized ecommerce business - moving from vmware to bare metal was fantastic on every level from api’s to performance and reliability. The enterprise spirit is stong in vmware.
