Kubectl & CLI Tools

Core

• ★ kubectl — the official CLI. Learn it; everything else is a wrapper.
• ★ kubectx + kubens — context / namespace switchers; ubiquitous.
• ★ k9s — TUI dashboard; navigate clusters interactively. Most-loved tool in the ecosystem.
• stern — multi-pod log tailer; far better than kubectl logs.

kubectl plugins (via krew)

• ★ krew — kubectl plugin manager; install everything below with kubectl krew install ….
• kubectl-tree — show ownerReferences as a tree.
• kubectl-neat — strip generated cruft from manifests.
• kubectl-view-secret — decoded secret values.
• kubectl-images — list images per pod / cluster.
• kubectl-warp — port-forward + interactive shell.
• kubectl-debug — ephemeral debug containers.
• kubectl-trace — bpftrace inside pods.
• kubectl-rolesum — summarize RBAC for a user / SA.
• kubectl-konfig — kubeconfig manipulation.

GUI / web dashboards

• ★ Lens — desktop GUI; extensive features; freemium.
• ★ Headlamp — open-source Lens alternative; CNCF.
• Octant (VMware, archived) — once-popular dashboard.
• k8sgpt — diagnostic CLI; explains why things are broken.
• Kubernetes Dashboard — official; clunky but works.
• Rancher Dashboard — multi-cluster UI bundled with Rancher.

Port forwarding / connection

• ★ kubectl port-forward — boring; works.
• kubefwd — forward all services in a namespace at once with hostname rewriting.
• Telepresence / mirrord — proxy local services into remote cluster.

Manifest manipulation

• yq — jq for YAML; essential.
• kustomize — built into kubectl.
• kubeconform — validate against schemas.
• kube-linter — best-practice scan.

Multi-cluster

• kubeconfig — flatten multiple clusters into one file.
• kubie — better kubectx with shell prompt integration.
• kubeshift — switch context + namespace in one command.

Productivity tips

• ★ Aliases. k=kubectl, kgp=kubectl get pods, etc. Most shells have premade kubectl alias bundles.
• Shell completion. kubectl completion + kubectx + kubens completion.
• KUBECONFIG with multiple files: export KUBECONFIG=~/.kube/config:./project.kube.
• KUBECTL_EXTERNAL_DIFF=dyff for human-readable diffs.
• kubectl -o jsonpath=… for scripting; or pipe through yq.

Don't sleep on

• kubectl explain — built-in schema docs for every resource type.
• kubectl events --watch — watch cluster events in real time.
• kubectl debug — ephemeral containers attached to a running pod.
• kubectl alpha events — newer events viewer with better UX.

Pick this if…

• Default daily driver: kubectl + krew + kubectx + kubens + k9s + stern.
• Visual cluster browsing: Lens or Headlamp.
• Debugging confusing failures: k8sgpt + kubectl debug.
• Multiple namespaces of services: kubefwd.
• Local ↔ remote during dev: Telepresence or mirrord.
