+# kubectl
+
+kubectl is the command-line tool for interacting with Kubernetes clusters. It lets you deploy applications, inspect resources, and manage cluster operations.
+
+## Install kubectl on Debian
+
+Add the Kubernetes APT repository, then install kubectl:
+
+```bash title="Add Kubernetes repository"
+cd ~/Tooling
+
+curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.32/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
+echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.32/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
+```
+
+```bash title="Install kubectl"
+sudo apt-get update
+sudo apt-get install -y kubectl
+```
+
+Verify the installation:
+
+```bash title="Check kubectl version"
+kubectl version --client
+```
+
+## Add kubectl to ToolingBins
+
+```bash title="Symlink kubectl"
+cd ~/ToolingBins
+ln -s /usr/bin/kubectl kubectl
+```
+
+## Configure kubectl
+
+kubectl uses a `kubeconfig` file (default: `~/.kube/config`) to locate and authenticate to Kubernetes clusters.
+
+To set a specific kubeconfig file for your session:
+
+```bash title="Set KUBECONFIG environment variable"
+export KUBECONFIG=~/.kube/my-cluster-config
+```
+
+To merge multiple kubeconfig files and switch between contexts:
+
+```bash title="List available contexts"
+kubectl config get-contexts
+```
+
+```bash title="Switch context"
+kubectl config use-context <context-name>
+```
+
+## Update kubectl
+
+```bash title="Update kubectl"
+sudo apt-get update
+sudo apt-get install --only-upgrade kubectl
+```
