Bastion Pod in Kubernetes
Background When deploying applications to kubernetes, we should restrict access to resources like databases, queues, cache, etc. From a security prospective, we should not be able to connect to storage/database from outside the kubernetes deployment(applications). Only applications deployed to kubernetes cluster should be allowed access to databases,queues, etc. Problem But for debugging purpose its essential to be able to connect to such resources. For e.g. we might need to check some data in the database or verify if an item is getting stored in redis cache, etc...
