Why your container image is 1.4 gigabytes
It should be forty megabytes. Here is where the rest of it came from and how to get it back.

State files, drift, modules that became frameworks, and the one practice that separates teams that like their IaC from teams that don't.
The state of self-hosting
Running your own infrastructure got dramatically easier while the industry was arguing about the cloud. A practical assessment.
