Kubernetes Operations

Kubernetes deployments across multiple environments require structured manifests, rolling updates, blue-green, and canary strategies. Configuring health checks and RBAC ensures reliable multi-environment deployments while reducing downtime and configuration errors.

Troubleshooting a Kubernetes cluster during incident response involves observing metrics, verifying readiness probes, and checking health checks. Applying performance tuning and security hardening practices minimizes cluster downtime and resolves operational issues.

Kubernetes autoscaling for statefulsets and DaemonSets works by managing resource allocation based on defined metrics. Proper resource management ensures deployments scale efficiently, maintaining cluster stability and performance under varying workloads.

Configuring Kubernetes ingress for load balancing involves defining service exposure rules and ingress configurations. Proper ingress setup routes external traffic to services effectively, ensuring reliable networking and access to deployed applications.

Establishing a new Kubernetes cluster for disaster recovery requires comprehensive deployment manifests, RBAC configurations, and monitoring setups. Security hardening and performance tuning are also essential to ensure ongoing cluster maintenance and operational resilience.

Use blue-green deployments instead of rolling updates in Kubernetes when you need immediate rollback capabilities and zero downtime. Rolling updates gradually replace instances, while blue-green switches traffic between two identical environments for safer releases.
