Discover how the Sealos team solved a critical disk exhaustion issue by optimizing a bloated 800GB container image down to 2GB. Learn our methods for squashing layers and manipulating OCI images to reclaim storage and boost performance.

In Kubernetes, managing resources efficiently in a multi-tenant or production environment is essential. Not all workloads are created equal—some are mission-critical, while others can tolerate delay or even eviction.

When resources are tight, Kubernetes needs a way to prioritize important workloads. That’s where Pod Priority comes into play — it helps the scheduler decide which pods should be scheduled first.

But what if the cluster is already at full capacity and a critical pod needs to be scheduled?

That’s where Preemption steps in. Kubernetes will evict lower-priority pods to free up space for higher-priority ones, ensuring that your most essential applications get the resources they need, even if it means removing less critical workloads.

Kite is a lightweight, modern Kubernetes dashboard that provides an intuitive interface for managing and monitoring your Kubernetes clusters. It offers real-time metrics, comprehensive resource management, multi-cluster support, and a beautiful user experience.
