Implementing Leader Election in Golang using Kubernetes API

Introduction Leader election is a crucial pattern in distributed systems where multiple instances or nodes compete to perform certain tasks. In a Kubernetes cluster, leader election can be used to ensure that only one instance is responsible for executing leader-specific tasks at any given time. This blog post will explore how to implement a leader election mechanism in Kubernetes using lease locks. Overview The leader election mechanism implemented in Go code relies on Kubernetes coordination features, specifically Lease object in the coordination.
