Running in Production Is a Podcast Where Devs Chat about Tech Stacks

In this episode of Running in Production, Nick Janetakis goes over building a podcast site with Jekyll and Ruby. It’s hosted on a single DigitalOcean server and has been running in production since October 2019.

Nick talks about what it takes to release an episode, keeping things simple, developing a custom audio player, hosting a bunch of sites on a single DigitalOcean server with nginx, using shell scripts to help reduce human errors and more.

Support the Show

This episode does not have a sponsor and this podcast is a labor of love. If you want to support the show, the best way to do it is to purchase one of my courses or suggest one to a friend.

• Dive into Docker is a video course that takes you from not knowing what Docker is to being able to confidently use Docker and Docker Compose for your own apps. Long gone are the days of "but it works on my machine!". A bunch of follow along labs are included.

• Build a SAAS App with Flask is a video course where we build a real world SAAS app that accepts payments, has a custom admin, includes high test coverage and goes over how to implement and apply 50+ common web app features. There's over 20+ hours of video.
