Upgrading Charts

We are about to install the go-demo-3 Chart. You should already be familiar with the commands, so you can consider this as an exercise that aims to solidify what you already learned. There will be one difference when compared to the commands we executed earlier. It'll prove to be a simple, and yet an important one for our continuous deployment processes.

We'll start by inspecting the values.

 1  helm inspect values helm/go-demo-3
