Kubernetes configuration can be complex, leading to mistakes that impact performance, security, and troubleshooting. Common misconfigurations include invalid YAML structures, overprovisioning of cloud resources, allowing privilege escalation in containers, missing resource limits for third-party integrations, and using a single container for all Ingress traffic. To prevent these issues, best practices include regularly updating Kubernetes, enabling version control for manifests, using minimal base images, isolating resources with namespaces, applying labels for maintenance, and utilizing network policies for pod isolation. These strategies minimize errors and enhance cluster performance and security. Komodor offers tools to help teams efficiently identify and resolve Kubernetes misconfigurations, while also focusing on cost optimization, health, and reliability.
