Is it possible to configure later (20+) versions of Ubuntu to NOT (ever) use containers such as snap and docker? So tired of seeing these tools consume all the resources. Would prefer to run natively as this is a stand-alone machine and doesn't need/warrant containers of any type.

Thanks!

Kind of a follow-up: If Ubuntu isn't capable of isolating itself from container reliance, is there a linux variant that will?

  • I would be careful classifying snaps as "containers". Containers implies that data on the container can change. Snaps are confined sandboxed applications whose code is a precompiled/prestored image and not able to be edited/revised/adjusted, so I would NOT consider Snaps as containers. If you don't want to use snaps, simply remove snapd. Same for Docker packages (which are NOT preinstalled on any standard Ubuntu images/installs). – Thomas Ward Jun 08 '22 at 16:44

    Does this answer your question? How to remove snap from Ubuntu? – Nmath Jun 08 '22 at 16:44
  • If ANY application "consume[s] all the resources", that's likely a bug. Some real troubleshooting is a good idea. I run a half-dozen real LXD containers on very-low-spec hardware, and a couple docker containers on other hardware, and the container overhead is negligible. – user535733 Jun 08 '22 at 22:03

    Anything not running natively is a container afaic as it adds some overhead to the existing system.

    I shut down a system today where the snaps and containers (for you, Thomas) were spazzing out my system to the point where the cpu was at 3% but load was hovering at over 9.0 and only snaps and dockers headed the active list. Geh. Great point about dockers not being native - I've no issue nuking those off the box. If there's not a native version of a snap app, then I don't need to run it. Thanks. Closing.

    Why are you talking about docker? It is not part of the default Ubuntu installation. If you installed docker, you may uninstall it. – user68186 Jun 09 '22 at 01:26
