This instalment is the second half of PBS Tidbit 17 in which Helma van der Linden is the instructor and Bart Busschots is the student. We pick up the plot right where Helma begins to teach how to reuse the Docker image created in the first half of the lesson.

This very special episode of Programming By Stealth is a Tidbit written and taught by the lovely Helma van der Linden. Bart has wanted to understand Docker better, and Helma has some great use cases for how to use them for developer setups so it was a good opportunity for Bart to learn from Helma.

The material is quite long, so the podcast was recorded in two segments, Tidbit 17a and b. Tidbit b will be along shortly, and picks up and the heading entitled "Reusing the Docker image".

Bart continues his unofficial series where he listens for where I say, "I wish I understood..." This time, he explains the history of how Podfeet.com has evolved over the last 20 years. We started with a shared server, then a virtual machine, to a dedicated server, and to a separate database server. He explains how the LAMP Stack works (Linux, Apache, MySQL, and PHP) and all the work Apache had to do. Then he explains how, when I moved Podfeet.com to NGINX + PHP-FPM, things got much more efficient. He even takes us through how Cloudflare protects my site and provides caching to speed up access to Podfeet.com to the benefit of all.
