Kubernetes is a popular orchestrator for container deployment and management, but it comes with its own set of challenges. This article explores 15 common pitfalls that many teams encounter while using Kubernetes, including deploying containers with the "latest" tag, not using liveness and readiness probes, broken pod affinity/anti-affinity rules, forgetting network policies, lack of monitoring and logging, label selector mismatches, service port mismatches, using multiple load balancers, accidentally deploying to the wrong namespace, pods without resource requests and limits, not budgeting for failure with PodDisruptionBudgets, incorrect cluster size and faulty auto-scaling, inefficient scheduling due to missing node selectors, relying on standard tools, and not using pod security admission standards. By recognizing and avoiding these challenges, users can improve their app's scalability, reliability, and security while gaining more control over their cluster and its deployments.
