This made me audibly guffaw. Kubernetes is a lot of things, but "portable" is not one of them. GKE, EKS, AKS, OCP, etc., portability between them is nowhere near guaranteed.
It is if you stick to standard Kubernetes resources, and it has gotten even easier with better storage class and load balancer support. All of the cloud providers now give you default storage classes and ingresses when you provision a cluster on them, so you can use the exact same deployment on any of them an automatically get those things provisioned in the right way out of the box.
