Install kubectl on Linux | Kubernetes CLI Guide

Install kubectl spikes whenever teams adopt Kubernetes — it is the CLI for every cluster API call. You need a working binary plus a kubeconfig with credentials for your cluster (kubeadm, managed EKS/GKE, or k3s).

Go deeper: kubeadm cluster setup,
Helm basics,
Docker on Linux.

kubectl and the API Server

kubectl sends HTTPS requests defined in your kubeconfig; context selects cluster and user.

Install the Binary

Official Kubernetes SIG release binaries are the common Linux install path.

bashLinux amd64

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
kubectl version --client

kubeconfig and Context

Copy admin kubeconfig from the control plane or cloud console into ~/.kube/config.

bashcontext

kubectl config get-contexts
kubectl config use-context my-cluster

kubectl get

List nodes, namespaces, pods — add -o wide for node IP and pod IP.

bashget

kubectl get nodes
kubectl get pods -A -o wide

describe and logs

Events explain scheduling failures; logs show container stdout.

bashdebug pod

kubectl describe pod mypod -n default
kubectl logs mypod --tail=100

exec and port-forward

Quick debugging without exposing services publicly.

bashexec

kubectl exec -it mypod -- sh

Verify Cluster Access

cluster-info confirms API reachability; auth errors mean fix kubeconfig or RBAC.

bashverify

kubectl cluster-info
kubectl get --raw='/readyz?verbose' 2>/dev/null | head

Quick Reference

Install: official kubectl binary in /usr/local/bin
~/.kube/config must match your cluster
Debug: describe + logs + get events
