Ops Health Check Skill

Comprehensive infrastructure health assessment covering cluster, nodes, workloads, networking, storage, and security.

Health Check Domains

1. Cluster Health

kubectl cluster-info
aws eks describe-cluster --name $CLUSTER_NAME --query 'cluster.{status:status,version:version,platformVersion:platformVersion}'
kubectl get componentstatuses 2>/dev/null

2. Node Health

kubectl get nodes -o wide
kubectl top nodes
kubectl get nodes -o json | jq '.items[] | {name:.metadata.name, ready:[.status.conditions[] | select(.type=="Ready") | .status][0], cpu:.status.allocatable.cpu, memory:.status.allocatable.memory}'

3. Workload Health

kubectl get pods -A --field-selector=status.phase!=Running,status.phase!=Succeeded | head -20
kubectl get deployments -A -o json | jq '.items[] | select(.status.unavailableReplicas > 0) | {name:.metadata.name, ns:.metadata.namespace, unavailable:.status.unavailableReplicas}'
kubectl get daemonsets -A -o json | jq '.items[] | select(.status.desiredNumberScheduled != .status.numberReady) | {name:.metadata.name, ns:.metadata.namespace, desired:.status.desiredNumberScheduled, ready:.status.numberReady}'

4. Network Health

kubectl get pods -n kube-system -l k8s-app=kube-dns -o wide
kubectl get pods -n kube-system -l k8s-app=aws-node -o wide
kubectl get svc -A --field-selector spec.type=LoadBalancer

5. Storage Health

kubectl get pvc -A --field-selector status.phase!=Bound
kubectl get pv --field-selector status.phase!=Bound,status.phase!=Released
kubectl get csidrivers

6. Security Health

kubectl get pods -A -o json | jq '[.items[] | select(.spec.containers[].securityContext.privileged==true) | {name:.metadata.name, ns:.metadata.namespace}]'
kubectl get networkpolicies -A
kubectl get podsecuritypolicies 2>/dev/null
