I decided to be crazy and attempt the level 3 challenge of converting an app I'm currently running in Docker over to Kubernetes. The crazy part is I picked my Nginx Proxy Manager on Docker to convert. To say it has been difficult would be an understatement. I'm doing it on a separate VM so I'm not messing up anything in production.
I did do a successful conversion of a MeshCentral Docker app, however. It had a few hiccups along the way but nothing compared to the NPM conversion.
