Migrate PVC from one storage class to another

This article introduces two methods for migrating a Persistent Volume Claim (PVC) from one storage class to another in Kubernetes: cloning the PVC using a CSI driver, and migrating using the Korb tool. The article provides detailed steps, requirements, and limitations for each method, and includes relevant example configuration files and command operations.

Kube Startup CPU Boost for Containers Initiating with Hunger

This article introduces the CPU Startup Boost feature in Kubernetes, which allows containers to receive additional CPU resources during startup to accelerate the startup process. By providing extra CPU resources, this feature is particularly helpful in addressing the “starvation” issue during container startup, enabling applications to respond and run faster. The article also discusses how to configure and utilize this feature in Kubernetes.
