Cluster Administration

Vapor provides tools for high-level administration of the Kubernetes cluster itself.

Node Management

Navigate to Kubernetes > Nodes to view all physical or virtual machines participating in the cluster.

For any Node, you can perform critical maintenance actions:

• Cordon: Mark the node as unschedulable, preventing the scheduler from placing new Pods onto it.
• Uncordon: Remove the scheduling restriction.
• Drain: Safely evict all Pods from the node (respecting PodDisruptionBudgets) in preparation for taking the node offline for maintenance or reboot.

Helm Charts & Releases

Vapor integrates with Helm, the package manager for Kubernetes.

• Repositories: Add and update Helm chart repositories.
• Charts: Browse available charts from configured repositories.
• Releases: View currently deployed Helm applications, check their status, and manage their lifecycles.

Custom Resource Definitions (CRDs)

CRDs allow you to extend the Kubernetes API with your own object types.

• View all CRDs registered in the cluster.
• Browse the specific instances (Custom Resources) created from those definitions. This is particularly useful for managing resources created by Operators (e.g., managing a database cluster deployed via a database Operator).
