I was a very early adopter of Docker and what sold me was Dockerfiles.

A SINGLE regular text file that took regular shell commands and could build the same deployment from scratch every time and then be cleaned up in one command.

This was UNHEARD of. Every other solution required learning new languages, defining “modules,” creating sets of scripts, or doing a lot of extra things. None of that was steezy.

I was so sold on Dockerfiles that I figured that even if the Docker project died, my Dockerfiles would continue to live because other people would try copy the idea of Dockerfiles. Now it’s been 10 years and Docker and containerization has changed a lot but what hasn’t? Dockerfiles. My 10 year Dockerfiles are still valid. That’s how good they were.
