Building images with Docker.md

Start with Docker

I've started trying stuff within my hosting machine so I'd more confidently build an image later. It didn't pay off. Just type inside the Dockerfile instead of the terminal (shell).

Give apprentice steps

Nevermind the state of the art when you're starting off:

  • Maximize the number of layers when you're playing around with stuff so you benefit the most of cached layers -- no need to run each command within a giant RUN directive

And then

  • Optimize (e.g.: wrap up everything within a single RUN) when you finished tweaking

First lessons could probably be generalized to anything else:

  • Commit to what you're learning (don't be afraid)
  • Take small steps
