Ever seen a perfectly healthy node refuse to schedule pods, even with plenty of CPU and memory? Most people get this wrong, but the answer is usually simpler than you think: Taints. In this reel, we dive into how Kubernetes uses Taints and Tolerations to control workload placement and ensure system stability. ๐ก Key Takeaways: Taints: These are applied to a node to "repel" pods unless they have a specific matching toleration. Tolerations: These are applied to pods, allowing them to be scheduled on nodes with matching taints. Why Use Them? Taints are perfect for isolating critical workloads, reserving nodes with specialized hardware (like GPUs), or keeping system components separate from application pods. The "Pending" Trap: If a pod lacks the necessary toleration for a tainted node, it will stay in a Pending state indefinitelyโeven if the node is underutilized!
