Resources for cloud independent architecture design?

Hi there! I've been tasked with lifting some existing architecture and build systems to the cloud. I want to go with Kubernetes or some solution that allows for little to no cloud vendor lock in, allowing system to be run on prem as well.

Can anybody recommend a book or other resources that deals with these requirements? I've read "Designing Data Intensive Applications" and find it wonderful. I wonder if there's something similar for architecture / kubernetes.

Thanks for your suggestion!
