If a container shares the same kernel with the host OS, how can Docker containers run in different OSes? Are people saying that what Docker containers really are "Docker VMs"?
- remram 5y agoIf you mean "how can Docker containers based on Linux run on Mac/Windows hosts", they don't. There is a single VM running Linux and the containers run inside of that.
- maccam94 5y ago"Docker for Mac" and "Docker for Windows" generally spin up a local Linux VM to run containers, but all of the containers run inside a single VM. (I'm going to gloss over running Windows containers on Windows, which I believe operate more like Linux containers do on Linux).
