go-demo-2 crashlooping #26

Closed talaniz closed 5 hours ago

talaniz commented 2 days ago

I'm getting a crashloop on the pod/go-demo-2.yml spec. I'm running a newer Mac so Virtualbox is not a driver I can select, I am instead using docker, not sure if that would make a difference. 

❯ kubectl create -f pod/go-demo-2.yml
pod/go-demo-2 created

❯ kubectl get -f pod/go-demo-2.yml

This is a repo I haven't used (or maintained) for a few years now.

Can you please let me know how you got to it? Are you following some of my books/videos/tutorials?

Sorry, I must have missed the github notification. I'm following the DevOps Toolkit 2.3

vfarcic commented 5 hours ago

That's a very old book. I stopped maintaining the repo used in it and removed the book from the shelves (at least those I have control of). Books are not very flexible and hard to maintain and I stopped writing them. Instead, now I focus on YouTube videos which are smaller in scope, less likely to go out of date, and easier to keep up-to-date. You'll find both beginners and more advanced topics around Kubernetes in https://youtube.com/@DevOpsToolkit.
