Comment on Should I move to Docker?
pete_the_cat@lemmy.world 6 months agoVMs have a ton of overhead compared to Docker. VMs replicate everything in the computer while Docker just uses the host for everything, except it sandboxes the apps.
In theory, VMs are far more secure since they’re almost entirely isolated from the host system (assuming you don’t have any of the host’s filesystems attached), they are also OS agnostic whereas Docker is limited to the OS it runs on.

Ah ok thanks, the security-aspect is indeed important to me. So I shouldn’t really use it for critical things. Especially those with external access.

Docker is still secure, it’s just less secure than Virtualization. It’s like a standard door knob lock (the twist/push button kind) vs a deadbolt. Both will keep 90% of bad-actors out but those who really want to get in can based on how high the security is.
