More kubectl commands

  • Check etcd health via apiserver
    kubectl get --raw '/healthz/etcd?verbose'

    Verify etcd connectivity through the apiserver health endpoint

  • Node metrics from metrics.k8s.io API
    kubectl get --raw '/apis/metrics.k8s.io/v1beta1/nodes' | jq '.items[] | {name:.metadata.name, cpu:.usage.cpu, mem:.usage.memory}'

    Raw node usage from metrics API; bypasses kubectl top formatting

  • Ephemeral debug copy with shared PIDs
    kubectl debug <pod> -n <ns> --copy-to=<pod>-dbg --share-processes --image=nicolaka/netshoot -- sleep infinity

    Clone pod with a debug container sharing the PID namespace; original stays untouched

  • Explain deployment spec recursively
    kubectl explain deploy.spec --recursive | less

    Dump the full nested field tree of a resource spec; great for hunting valid fields

  • Pause and resume a rollout
    kubectl rollout pause deploy/<name> -n <ns>; kubectl rollout resume deploy/<name> -n <ns>

    Batch multiple edits without triggering rollouts, then resume to apply once
