DaemonSet anti-patterns refer to practices in Kubernetes that can result in inefficiencies, resource bloat, or operational issues when deploying DaemonSets. A DaemonSet ensures that a copy of a pod runs on each node in a Kubernetes cluster, which is critical for tasks like logging and monitoring. However, when not implemented with consideration of specific scenarios, they can lead to significant drawbacks.
Understanding these anti-patterns matters in DevOps as it helps teams optimize their resource usage, minimize unnecessary complexity, and improve system reliability. Avoiding these pitfalls ensures that applications run smoothly, resources are efficiently allocated, and operational overhead is minimized.

// Example of a DaemonSet anti-pattern

limits:
memory: "256Mi" // Potential anti-pattern: Overly restrictive limits can cause evictions
cpu: "1" // Avoid setting limits too low for heavy workloads
