wait-for-k8s-node-ready

Poll until a Kubernetes node reaches Ready or NotReady.

Problem

Node maintenance scripts (drain, reboot, uncordon) need a reliable wait loop instead of fixed sleep calls. This script polls kubectl until the node reports the desired Ready condition or a timeout is reached.

Requirements

• bash
• kubectl configured for the target cluster
• Permission to get nodes

Usage

./wait-for-k8s-node-ready.sh <node-name> <ready|notready> [timeout_seconds]

Examples:

./wait-for-k8s-node-ready.sh worker-1 notready 180
./wait-for-k8s-node-ready.sh worker-1 ready 600

Exit code 0 on success, 1 on timeout or invalid arguments.

Limits

• Watches the Ready condition only.
• Uses the current kubectl context; no context flag is provided.
• Progress is printed as dots every two seconds.
