Docker containers aren't provably secure. If you want isolation, use a VM that doesn't have host file system access. This way, if the VM is compromised, just throw it away and it can't leak out the way containers do.
- px43 5y ago> Docker containers aren't provably secure. Not only are they not provably secure (very few things are), they are explicitly not intended for use as a security boundary. Their whole gimmick is lightweight containers you can use instead of VMs if you trust everyone who's going to run code under them.
- airhead969 5y agoTo disambiguate: I don't mean formal verification like seL4, I mean it hasn't been thoroughly audited to show it is reasonably secure. Docker security of images and running containers is pretty shit as I brought up on GH in the beginning. Developers just shrugged it off and focused on whiz-bang features. The conflation of what amounts to fancy Linux cgroups trickery with hypervisors is a depressing misunderstanding of isolation.
