Kubernetes Best Practices for Production

Resource Management

Always define both resource requests and limits for every container. Without limits, a misbehaving pod can impact the entire node.

Health Checks

Implement both liveness and readiness probes for reliable service routing.

Network Policies

Implement network policies to enforce least-privilege communication between services.

Observability

A production cluster needs Prometheus metrics, structured logging with Fluentd, and distributed tracing with OpenTelemetry.
