How to expose pod level metrics (for example, CPU/memory usage) for a particular kubernetes pod running a docker container for prometheus? Does kubernetes has in built metric exposing or do I have to write an exporter by myself to expose pod level metrics and then host it at a specific port?

Starting from Kubernetes 1.8, resource usage metrics, such as container CPU and memory usage, are available in Kubernetes through the Metrics API
If you want more pod specific metrics (let say that you want to collect java metrics like heap, gc and so on) you can use a prometheus exporter and scrape that info, but it all depends on the tech you want to use.
