Install the Kubernetes CLI

Estimated reading time: 2 minutes

Docker EE 2.0 and higher deploys Kubernetes as part of a UCP installation. Deploy, manage, and monitor Kubernetes workloads from the UCP dashboard. Users can also interact with the Kubernetes deployment through the Kubernetes command-line tool named kubectl.

To access the UCP cluster with kubectl, install the UCP client bundle.

Kubernetes on Docker for Mac and Docker for Windows

Docker for Mac and Docker for Windows provide a standalone Kubernetes server that runs on your development machine, with kubectl installed by default. This installation is separate from the Kubernetes deployment on a UCP cluster. Learn how to deploy to Kubernetes on Docker for Mac.

Install the kubectl binary

To use kubectl, install the binary on a workstation which has access to your UCP endpoint.

Must install compatible version

Kubernetes only guarantees compatibility with kubectl versions that are +/-1 minor versions away from the Kubernetes version.

First, find which version of Kubernetes is running in your cluster. This can be found within the Universal Control Plane dashboard or at the UCP API endpoint version.

From the UCP dashboard, click on About Docker EE within the Admin menu in the top left corner of the dashboard. Then navigate to Kubernetes.

Find Kubernetes version

Once you have the Kubernetes version, install the kubectl client for the relevant operating system.

# Set the Kubernetes version as found in the UCP Dashboard or API
k8sversion=v1.8.11

# Get the kubectl binary.
curl -LO https://storage.googleapis.com/kubernetes-release/release/$k8sversion/bin/darwin/amd64/kubectl

# Make the kubectl binary executable.
chmod +x ./kubectl

# Move the kubectl executable to /usr/local/bin.
sudo mv ./kubectl /usr/local/bin/kubectl

# Set the Kubernetes version as found in the UCP Dashboard or API
k8sversion=v1.8.11

# Get the kubectl binary.
curl -LO https://storage.googleapis.com/kubernetes-release/release/$k8sversion/bin/linux/amd64/kubectl

# Make the kubectl binary executable.
chmod +x ./kubectl

# Move the kubectl executable to /usr/local/bin.
sudo mv ./kubectl /usr/local/bin/kubectl

You can download the binary from this link

If you have curl installed on your system, you use these commands in Powershell.

$env:k8sversion = "v1.8.11"

curl https://storage.googleapis.com/kubernetes-release/release/$env:k8sversion/bin/windows/amd64/kubectl.exe

Using kubectl with a Docker EE cluster

Docker Enterprise Edition provides users unique certificates and keys to authenticate against the Docker and Kubernetes APIs. Instructions on how to download these certificates and how to configure kubectl to use them can be found in CLI-based access.
