Interesting, what OS are you running? I’ve never ran into one that it doesn’t work on so that’s surprising.

I would counter that disadvantage with this: due to testing constraints, docker containers are usually updated more quickly when there’s a 0 day, and you don’t have to patch your entire OS if one single container has one. It reduces operator overhead greatly, because that’s what it’s designed to do. Even if one of your containers has a vulnerability, because it’s a container, it won’t necessarily affect your entire system, depending on the vulnerability.
