Hi I am new to microservices architect and have few questions related to its deployment on production environment. I am using spring boot microservices and want to deploy them on any open source plantform like kubernetes. Previously I have all deployments on local servers(conventional hardware). So I don't want to move to any cloud service for now, its part of future planing. I want to have a deployment strategy that should work with servers and in future when I want to move to cloud, effort should be minimum. I need some expert suggestions. I have created a POC of deploying apps to kubernetes with minikube where I am using docker container. But for docker private repositories I need to buy their enterprise services. And for any cloud platform I also need invest money.

What are the other choices where I can deploy microservices on my conventional hardware.

Caas vs PaaS, CF vs K8s
