Kubernetes, while powerful, presents many potential pitfalls for users. One common mistake is neglecting resource requests and limits within Pod specifications, leading to potential resource starvation or hoarding. Underestimating liveness and readiness probes is another issue, as this can result in unresponsive services and user disruptions. Relying solely on "kubectl logs" for logging can cause critical information loss due to container lifecycles. Treating development and production environments identically can lead to performance issues and security vulnerabilities. Leaving obsolete resources undeleted consumes resources and complicates management. Diving into complex networking before understanding the basics makes troubleshooting difficult. Finally, skimping on security and RBAC can leave clusters exposed to various risks. These common errors can be avoided by adopting best practices and understanding Kubernetes' core functionalities. The author encourages users to learn from mistakes and use official documentation and community resources.
