Docker Desktop includes a standalone Kubernetes server and client,
|
|
as well as Docker CLI integration that runs on your machine.
|
|
|
|
The Kubernetes server runs locally within your Docker instance, is not configurable, and is a single-node cluster. It runs within a Docker container on your local system, and
|
|
is only for local testing.
|
|
|
|
Enabling Kubernetes allows you to deploy
|
|
your workloads in parallel, on Kubernetes, Swarm, and as standalone containers. Enabling or disabling the Kubernetes server does not affect your other
|
|
workloads.
|
|
|
|
## Enable Kubernetes
|
|
|
|
To enable Kubernetes in Docker Desktop:
|
|
1. From the Docker Dashboard, select the **Settings**.
|
|
2. Select **Kubernetes** from the left sidebar.
|
|
3. Next to **Enable Kubernetes**, select the checkbox.
|
|
4. Select **Apply & Restart** to save the settings and then click **Install** to confirm. This instantiates images required to run the Kubernetes server as containers, and installs the `/usr/local/bin/kubectl` command on your machine.
|
|
|
|
By default, Kubernetes containers are hidden from commands like `docker ps`, because managing them manually is not supported. Most users do not need this option. To see these internal containers, select **Show system containers (advanced)**.
|
|
|
|
When Kubernetes is enabled and running, an additional status bar in the Dashboard footer and Docker menu displays.
|
|
|
|
> Note
|
|
>
|
|
> Docker Desktop does not upgrade your Kubernetes cluster automatically after a new update. To upgrade your Kubernetes cluster to the latest version, select **Reset Kubernetes Cluster**.
|
|
|
|
## Use the kubectl command
|
|
|
|
Kubernetes integration provides the Kubernetes CLI command
|
|
at `/usr/local/bin/kubectl` on Mac and at `C:\Program Files\Docker\Docker\Resources\bin\kubectl.exe` on Windows. This location may not be in your shell's `PATH`
|
|
variable, so you may need to type the full path of the command or add it to
|
|
the `PATH`.
|
|
|
|
The kubectl binary is not automatically packaged with Docker Desktop for Linux. To install the kubectl command for Linux, see [Kubernetes documentation](https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/){:target="_blank" rel="noopener" class="_"}. It should be installed at `/usr/local/bin/kubectl`.
|
|
|
|
If you have already installed `kubectl` and it is
|
|
pointing to some other environment, such as `minikube` or a GKE cluster, ensure you change the context so that `kubectl` is pointing to `docker-desktop`:
|
|
|
|
```console
|
|
$ kubectl config get-contexts
|
|
$ kubectl config use-context docker-desktop
|
|
```
|
|
|
|
>Note
|
|
>
|
|
> Run the `kubectl` command in a CMD or PowerShell terminal, otherwise `kubectl config get-contexts` may return an empty result.
|
|
>
|
|
>If you are using a different terminal and this happens, you can try setting the `kubeconfig` environment variable to the location of the `.kube/config` file.
|
|
|
|
If you installed `kubectl` using Homebrew, or by some other method, and
|
|
experience conflicts, remove `/usr/local/bin/kubectl`.
|
|
|
|
You can test the command by listing the available nodes:
|
|
|
|
```console
|
|
$ kubectl get nodes
|
|
|
|
NAME STATUS ROLES AGE VERSION
|
|
docker-desktop Ready master 3h v1.19.7
|
|
```
|
|
|
|
For more information about `kubectl`, see the
|
|
[`kubectl` documentation](https://kubernetes.io/docs/reference/kubectl/overview/){:target="_blank" rel="noopener" class="_"}.
|
|
|
|
## Disable Kubernetes
|
|
|
|
To disable Kubernetes in Docker Desktop:
|
|
1. From the Docker Dashboard, select the **Settings** icon.
|
|
2. Select **Kubernetes** from the left sidebar.
|
|
3. Next to **Enable Kubernetes**, clear the checkbox
|
|
4. Select **Apply & Restart** to save the settings.This stops and removes Kubernetes containers, and also removes the `/usr/local/bin/kubectl` command.
