There are tools that let you convert a running docker/podman container to a kubernetes deployment manifest which you can then deploy with one line command to your cluster. Kubernetes is the new data center and I don’t expect anyone with <10 years of enterprise experience to master it. Certainly one can use it and deploy things to it if you work at a place where there are mature pipelines, but deploying your own cluster and all associated services plus networking plus security is the domain of experienced/senior engineers. How quickly one achieves that “status” is up to the individual. It took me 15 years before I could build an enterprise network from scratch. It took me two years to understand how to do the same with K8s.
