More kubectl commands

  • 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

  • View last applied configuration
    kubectl apply view-last-applied deploy/<name> -n <ns> -o yaml

    Show the last-applied-configuration annotation; diff intent vs live state

  • Warning events across all namespaces
    kubectl get events -A --field-selector type=Warning --sort-by=.lastTimestamp

    Cluster-wide Warning events newest last; fast triage of failing workloads

  • Find all failed pods cluster-wide
    kubectl get pods -A --field-selector status.phase=Failed

    List pods in Failed phase across namespaces for cleanup or investigation

  • Wait on a jsonpath condition
    kubectl wait --for=jsonpath='{.status.loadBalancer.ingress[0].ip}' svc/<name> -n <ns> --timeout=120s

    Block in CI until a Service gets its external IP; works on any jsonpath field
