The Kubernetes command-line interface (CLI), `kubectl`, can be used to run commands against a Kubernetes cluster. Because {microshift-short} is a certified Kubernetes distribution, you can use the supported `kubectl` CLI tool or you can gain extended functionality by using the {oc-first}.

|
== The kubectl CLI tool
|
|
|
|
You can use the `kubectl` CLI tool to interact with Kubernetes primitives on your {microshift-short} node. You can also use existing `kubectl` workflows and scripts for users coming from another Kubernetes environment, or for those who prefer to use the `kubectl` CLI.
|
|
|
|
* The `kubectl` CLI tool is included in the archive when you download `oc`.
|
|
|
|
* For more information, see the link:https://kubernetes.io/docs/reference/kubectl/overview/[Kubernetes CLI tool documentation].

|
|
== The oc CLI tool
|
|
|
|
The `oc` CLI tool offers the same capabilities as the `kubectl` CLI tool, but it extends to natively support additional {OCP} features, including:
|
|
|
|
* **Route resource**
|
|
+
|
|
The `Route` resource object is specific to {OCP} distributions, and builds upon standard Kubernetes primitives.
|
|
+
|
|
* **Additional commands**
|
|
+
|
|
The additional command `oc new-app`, for example, makes it easier to get new applications started using existing source code or pre-built images.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
If you installed an earlier version of `oc`, you might not be able use it to complete all of the commands in {microshift-short} {product-version}. If you want the latest features, you must download and install the latest version of `oc` that corresponds with your {microshift-short} version.
|
|
====
|
|
|
|
Using new capabilities often requires the latest `oc` binary. A 4.21 server might have additional capabilities that a 4.16 `oc` binary cannot use and a 4.21 `oc` binary might have additional capabilities that are unsupported by a 4.15 server.
