A Live Demo of Maintaining 6 Open Source Docker Example Web Apps
I recorded every step of the way when updating a bunch of packages and services. From the idea to tweeting out the end result.
Quick Jump: Demo Video
I figured it would be fun to record the entire process just to give an idea on what it looks like to update a few Docker example apps.
Through out the demo we’ll cover using tmux, Vim, writing and amending git commit messages, updating a changelog and tweeting out the end result. Perhaps a takeaway from the video will be seeing something in my workflow that helps you out in your day to day.
