Kubernetes Production Readiness Checklist - Explained ??

? Ensure robust, secure, and reliable #Kubernetes deployments with this detailed production readiness checklist!

1???Scalability

• Implement Horizontal Pod Autoscaling (HPA) to automatically scale pods according to CPU & memory utilization.
• Use Cluster Autoscaling to add or remove cluster nodes based on resource needs.

2???Resource Management

• Set?resources.requests?&?resources.limits?to manage resource allocation per container.
• Employ Pod Disruption Budgets (PDB) to limit the number of disrupted pods during maintenance.

3???Health Checks

• Configure?livenessProbe?to restart unhealthy containers.
• Configure?readinessProbe?to determine when a container is ready to accept traffic.

4???Rollout & Rollback

• Adopt Rolling Updates for zero-downtime deployments.
• Leverage sophisticated deployment strategies such as Blue-Green & Canary for additional safety & control.

5???Monitor & Log

• Implement centralized logging with Fluentd, Logstash, or similar solutions to collect logs from all containers.
• Monitor with tools like Prometheus (metrics collection) and Grafana (visualization).

6???Security

• Use Role-Based Access Control (RBAC) to restrict resource access.
• Implement network policies to control ingress & egress traffic.
• Manage secrets securely using Kubernetes Secrets or third-party tools.

7???Configuration Management

• Utilize ConfigMaps & Secrets for non-sensitive and sensitive configuration data.
• Prefer immutable infrastructure and minimize running non-replicated processes.

8???Graceful Shutdown

• Implement?preStop?hook to perform cleanup tasks or gracefully terminate connections.
• Set?terminationGracePeriodSeconds?to give containers time to complete preStop tasks.

9???Backup & Disaster Recovery

• Backup Kubernetes objects (e.g., ConfigMaps, Secrets, Deployments).
• Regularly practice disaster recovery scenarios and update plans accordingly.
