I have deployed on Minikube, woah! A great fastlane into Kubernetes Kubernetes for Devs @LostInBrittany

Running a full K8s in your laptop A great learning tool Kubernetes for Devs @LostInBrittany

Your laptop isn’t a true cluster Don’t expect real performances Kubernetes for Devs @LostInBrittany

Minikube is only the beginning Kubernetes for Devs @LostInBrittany

From Minikube to prod A journey not for the faint of heart Kubernetes for Devs @LostInBrittany

The truth is somewhere inside… Kubernetes for Devs @LostInBrittany

The network is going to feel it… Kubernetes for Devs @LostInBrittany

The storage dilemma Kubernetes for Devs @LostInBrittany
