Did you know Docker Desktop runs a virtual machine on your computer?

yellow_lead 5y ago
A "fun" thing about Docker Desktop on Windows is that it requires Hyper-V. And it so happens that Hyper-V is usually incompatible with AMD SVN (Their virtualization acceleration). So it's impossible to simulatenously use VirtualBox and Docker Desktop, unless you're okay with horrible performance on the latter.

  I'm running both Docker and VirtualBox on my 5950x in Win11; don't remember doing anything special, but VirtualBox chose Hyper-V as the hypervisor technology, maybe it didn't default to that for you.

  Personally, i think that VirtualBox is really nice as far as virtualization software goes (the UI in particular having good usability), but admittedly Hyper-V is also good for when you cannot run it. That said, for a while i actually ran VirtualBox on some of my homelab servers as a really simple hypervisor, since software like RemoteBox kept the familiar and easy to use UI and allowed me to use it as a desktop app: https://remotebox.knobgoblin.org.uk/?page=about https://remotebox.knobgoblin.org.uk/?page=about Of course, Docker Desktop also supports WSL2 on Windows instead of Hyper-V, so it's not like you're always forced to use it: https://docs.docker.com/desktop/windows/wsl/ https://docs.docker.com/desktop/windows/wsl/ On an unrelated note, Rancher Desktop also seems promising: https://rancherdesktop.io/ https://rancherdesktop.io/

    WSL2 requires hyper-v, so you need it for Docker either way.

      Huh. Seems like it's more interesting than that: https://github.com/MicrosoftDocs/WSL/issues/899 https://github.com/MicrosoftDocs/WSL/issues/899 > ...for WSL2 you only need "Virtual Machine Platform" (a subset of Hyper-V) and "Windows Subsystem for Linux" features, both available in Home edition. Also there's this: https://docs.microsoft.com/en-us/windows/wsl/faq#will-i-be-able-to-run-wsl-2-and-other-3rd-party-virtualization-tools-such-as-vmware--or-virtualbox- https://docs.microsoft.com/en-us/windows/wsl/faq#will-i-be-a... > However, recently both VirtualBox and VMware have released versions that support Hyper-V and WSL2. Learn more about VirtualBox's changes here and VMware's changes here. For troubleshooting issues, take a look at the VirtualBox issue discussions in the WSL repo on GitHub.

Am I getting confused or didn’t you used to have to install VirtualBox to run Docker Desktop on macOS? I don’t see this in their installation instructions any more…

  docker-machine, which predated Docker Desktop, used VirtualBox; you may be thinking of that. I don't think Docker Desktop ever used VirtualBox.
