+# kubectl
+
+kubectl is the main command line tool for k8s. See [reference](https://kubernetes.io/docs/reference/kubectl/conventions/)
+
+## Raw commands
+
+Sometimes it's handy to just run a container without all the yaml mess.
+
+### Running a container
+
+```sh
+kubectl run --image=IMAGE name
+```
+
+### apply is not always the answer
+
+Even if you see `kubectl apply` everywhere sometimes it's handy to use dedicated commands
+
+For example, `kubectl create` is used to create a ressource and will throw an error if a ressource already exists.
+
+### Generating a manifests, blazzing fast way
+
+```sh
+kubectl run app --image=app --dry-run=client -o yaml
+```
+
+```sh
+kubectl create deployment --image=redis redis --dry-run=client -o yaml
+```
+
+Of course, if you need to write it into a file
+
+```sh
+kubectl create deployment --image=redis redis --dry-run=client -o yaml > deploy-manifest.yml
+```
+
+### Switching namespaces contexts
+
+```sh
+kubectl config set-config $(kubectl config current-context) --namespace=target
+```
