Running a Kubernetes Cluster in your own data center on Bare Metal hardware can be lots of fun but also can be challenging. One of the changeless are exposing your service to an external Load Balancer, Kubernetes does not offer an implementation of an external load-balancer for bare metal cluster implementations. The Kubernetes implementations of Network Load Balancers are only available on specific Cloud Providers like AWS, GCP, Azure, etc.. and is enabled by specifying the –cloud-provider= option. leaving a gap/challenge if you create your own Bare Metal Kubernetes Cluster. While their are many workarounds to address this issue most of them are not perfect and have their own list of challenges. while I was looking for a for a solution, most recently came across a project called MetalLB, at first I was quite sceptical if its going to work, but after testing this for a while I have to say, I am quite happy with the solution.
