Run your own registry.

Or run no registry. Here's a port from a Dockerfile to just a vm:

FROM Debian

CMD apt-get install thing

CMD curl blabla/install.sh

Pretty much converts to:

aws-cli ec2 launch-instance

ssh user@server apt-get install thing

ssh user@server curl blabla/install.sh

In general, everytime you dispense of a high level abstraction, the solution is not to replicate the high level abstraction, but to build directly at a lower level abstraction.

If you want to replace burgers, just buy a slab of meat and put it in the fire or bake your own bread. You don't need to make preservants and buy artificial sweeteners, etc...

Yeah, no.

I'm not only using containers to deploy my VPSes.

Thank you for trying.

P.S. at least use something declarative and provider-agnostic like terraform.

What else are you using containers for?

Testing things on my laptop and deploying services to my home lab. Both benefit enormously from the minimal overhead, fast deployment, and ease of completely removing a service once I'm done with it.

Ah yes, that was one of the main selling points of docker early on, fixing the "works on my machine".

The way I solve that problem is by working directly on testing/staging servers which have the same specs as production.

I almost never run stuff on my local machine, and if I do it's a well isolated piece of code whose IO signature I know exactly and I can mock external systems with ease.
