People gravely miss-understand containerization and Docker.

All it lets you do is put shell commands into a text file and be able to run it self-contained anywhere. What is there to hate?

You still use the same local filesystem, the same host networking, still rsync your data dir, still use the same external MySQL server even if you want -- nothing has changed.

You do NOT need a load balancer, a control plane, networked storage, Kubernetes or any of that. You ADD ON those things when you want them like you add on optional heated seats to your car.

Why would you want to run it anywhere. People mostly select an OS and just update that. It may be great when distributing applications for others to host, but not when it’s the only strategy. I have to reverse engineer dockerfiles when the developer wouldn’t provide a proper documentation.
