kubectl describe pod <pod-name>

kubectl describe node <node-name> | grep -A 10 Conditions

kubectl get pods --field-selector=status.phase=Failed | grep Evicted | awk '{print $1}' | xargs kubectl delete pod

# Delete across all namespaces
kubectl get pods -A --field-selector=status.phase=Failed | grep Evicted | awk '{print $1 " -n " $2}' | xargs -L1 kubectl delete pod

  requests:
    memory: "256Mi"

# Check node memory
kubectl top nodes

# Check pod memory usage
kubectl top pods --sort-by=memory

# On the node, check disk usage
df -h
du -sh /var/lib/docker/*
du -sh /var/lib/containerd/*
du -sh /var/log/*

# Remove unused images
crictl rmi --prune

# Clean container logs (careful - loses logs)
truncate -s 0 /var/lib/docker/containers/*/*-json.log
