I finally tried using containers in my homelab

Noticed more folks asking about Docker setups at work lately. My hobby project with containers taught me a ton about keeping apps separate, tbh. It's so much smoother than messing with full VMs.

I get the appeal, but I still lean on VMs for real isolation sometimes. Running an old Linux distro or testing sketchy code just feels safer in its own full machine. Containers are great for app stuff, but they share the host kernel, which can be a real weak spot.

Used to agree until a kernel exploit changed my view.

Kernel flaws really do change your perspective. I was big on containers until a local privilege escalation showed their weakness. Now I default to VMs for anything questionable. Isn't it crazy how one bug can undermine so much trust?

But what about all the holes in VM software that show up too? Remember when that escape bug let people break out of the guest? Containers spin up instantly and save so much memory, they're perfect for normal workloads. Kernel issues usually get fixed fast, and with tight security settings, the threat is pretty low. Ditching containers for every little scare seems like throwing the baby out with the bathwater, lmao.
