To create a Kubernetes deployment manifest for a stateless microservice, define a Deployment resource in YAML specifying your container image, replicas, and Pod templates. This Skill guides you in crafting optimal manifests that incorporate health checks and resource limits for reliable production deployments.

Best practices for Kubernetes resource limits and autoscaling involve setting explicit CPU and memory requests and limits in your Pod specs, then configuring Horizontal Pod Autoscalers (HPA) or Vertical Pod Autoscalers (VPA). This ensures applications scale dynamically and maintain operational excellence under varying loads.

Configuring Kubernetes Secrets and ConfigMaps securely involves decoupling configuration data from container images by defining these resources in your YAML manifests. This Skill provides guidance on managing sensitive data and configurations while applying Pod Security Contexts to enforce security best practices.

The best way to implement rolling updates and canary deployments in Kubernetes is by defining specific deployment strategies within your Deployment manifest. This Skill covers these strategies along with Blue/Green deployments to ensure zero-downtime releases and resilient application updates.

Kubernetes deployment for production workloads strongly requires Network Policies and Role-Based Access Control (RBAC) to restrict traffic and secure cluster access. This Skill acts as an expert advisor, detailing these security best practices alongside image security to protect your microservices.

You should use Ingress instead of a standard Kubernetes Service when you need to manage external HTTP/HTTPS access to multiple microservices through a single entry point. This Skill provides comprehensive guidance on configuring Services and Ingress for optimal traffic routing in cloud-native environments.
