We Need to Talk About Docker Hub

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...

and who hosts that Debian image you're starting from....
