While I can understand the sentiment, this is a REALLY bad and irresponsible thing to do and detrimental to yourself and society as a whole.
Lemmy, please do everything you can to set yourself up for a successful retirement. Even just a small contribution to a retirement account really will make a big difference when you're older.
If you're doing it right, containers are less like VMs and more like cgroups. If orchestrated correctly it uses less system resources to run lots of services on a single system/node.
That said, I'm a devops/infrastructure/network professional and not a developer, so maybe I'm missing something from the dev experience.... But I love containers.
Docker does kinda suck now, though. Use podman or another interface instead if you can help it.
