Fixes JupyterHub spawn timeouts when a singleuser pod stays Pending on a full Kubernetes node. Use for spawn timeouts caused by node pressure or resource requests. Not for image-pull failures, proxy errors, or auth problems.
This skill walks through recovering an etcd cluster that rejects writes with mvcc: database space exceeded. It covers confirming the NOSPACE alarm, defragging members one at a time, disarming the alarm, and setting up automatic compaction. Reach for it whenever etcd writes fail while disk space looks fine.

Distinguishes the two causes behind container exit code 137: OOMKilled (the container exceeded its memory limit) versus node-pressure eviction (the node ran out of memory). Shows how to read the termination reason and fix each. Reach for it when a container dies with 137 and you need to know which memory problem it wa…

Fixes the Kubernetes mount failure where MountVolume.SetUp fails with exit status 32. Shows how to read the device path from the event, check the filesystem on the node, and fix fstype mismatches or corrupt volumes. Reach for it when a pod cannot mount an attached block volume.
Debugs pod evictions caused by the node.kubernetes.io/unreachable NoExecute taint. Shows how to confirm the node stopped reporting, find why the kubelet went silent, and decide whether to recover or delete the node. Reach for it when pods get evicted after a node goes NotReady.

Fixes Kubernetes API 429 Too Many Requests errors caused by client-side throttling. Shows how to identify the hot client from audit logs, then raise its QPS and burst settings or reduce request churn. Reach for it when controllers or automation start failing with 429s under load.

Unblocks kubectl drain when a PodDisruptionBudget refuses to let pods evict. Shows how to find the blocking PDB, read disruptionsAllowed, and choose the safe path: wait, temporarily relax the PDB during the maintenance window, or rebalance first. Reach for it whenever a drain aborts on PDB protection.
Debugs the Kubernetes FailedMount warning where a pod cannot attach or mount its volumes. Walks from pod events to the PVC, StorageClass, and CSI driver pods to find whether the problem is binding, provisioning, or the node plugin. Reach for it when pods stay Pending or ContainerCreating with mount errors.

Fixes pods stuck Pending with unbound immediate PersistentVolumeClaims. Shows how to check PVC binding state, StorageClass defaults, and the provisioner to find why no PersistentVolume is being created. Reach for it when new PVCs sit in Pending and the pod never schedules.
