+# kubectl debug
+
+> Debug cluster resources using interactive debugging containers.
+> More information: <https://kubernetes.io/docs/reference/kubectl/generated/kubectl_debug>.
+
+- Create an interactive debugging session in a pod and immediately attach to it:
+
+`kubectl debug {{pod_name}} {{[-it|--stdin --tty]}} --image busybox`
+
+- Create a debug container with a custom image and name:
+
+`kubectl debug --image {{image}} {{[-c|--container]}} {{container_name}} {{pod_name}}`
+
+- Create an interactive debugging session on a node and immediately attach to it (the container will run in the host namespaces and the host's filesystem will be mounted at `/host`):
+
+`kubectl debug node/{{node_name}} {{[-it|--stdin --tty]}} --image busybox`
+
+- Create a copy of a pod and add a debug container to it:
+
+`kubectl debug {{pod_name}} {{[-it|--stdin --tty]}} --image {{image}} --copy-to {{pod_copy_name}}`
+
+- Create a copy of a pod and change the command of a specific container:
+
+`kubectl debug {{pod_name}} {{[-it|--stdin --tty]}} --copy-to {{pod_copy_name}} --container {{container_name}} -- {{command}}`
+
+- Create a copy of a pod and change the image of a specific container:
+
+`kubectl debug {{pod_name}} --copy-to {{pod_copy_name}} --set-image {{container_name}}={{image}}`
+
+- Create a copy of a pod and change all container images:
+
+`kubectl debug {{pod_name}} --copy-to {{pod_copy_name}} --set-image '*={{image}}'`
+
+- Create an ephemeral debug container and target a specific container (useful for debugging distroless containers):
+
+`kubectl debug {{pod_name}} {{[-it|--stdin --tty]}} --image {{image}} --target {{target_container_name}}`
