Sure, docker-compose is great, but could we get similar functionality using just the tools that are built into CoreOS? Can we get automatic updates, too? Yes we can! 📦
I think you’re interpreting too much. Security is about layers and making it harder for attackers, and that’s exactly what using a non-root user does.
In that scenario, the attacker needs to find and exploit another vulnerability to gain root access, which takes time - time which the attacker might not be willing to spend and time which you can use to respond.
You don’t know enough about security to lecture me. The kernel has before/continues to suffer(ed) from successful root shell exploits, particularly in this case via unprivileged userns. Something podman or even rootless docker can’t do anything about.
Funny how you claim to know so much about security but can’t even seem to comprehend my comment. I know root shell exploits exist, that’s why I wrote that it takes additional time to get root access, not that it’s impossible. And that’s still a security improvement because it’s an additional hurdle for the adversary.
Containers cannot be viewed as security tools. They suffer from poor isolation and inadequate and some cases non-existent sandboxing. All these are proven security essentials. You would know about them if you knew anything about (defensive) security!
