To deploy and manage applications on Kubernetes, you’ll use the Kubernetes command-line tool, kubectl. It lets you inspect your cluster resources, create, delete, and update components, and much more. You will use it to look at your new cluster and bring up example apps.
If you downloaded a pre-compiled release, kubectl should be under
platforms/<os>/<arch> from the tar bundle.
If you built from source, kubectl should be either under
The kubectl binary doesn’t have to be installed to be executable, but the rest of the walkthrough will assume that it’s in your PATH.
The simplest way to install is to copy or move kubectl into a dir already in PATH (e.g.
/usr/local/bin). For example:
# OS X $ sudo cp kubernetes/platforms/darwin/amd64/kubectl /usr/local/bin/kubectl # Linux $ sudo cp kubernetes/platforms/linux/amd64/kubectl /usr/local/bin/kubectl
You also need to ensure it’s executable:
$ sudo chmod +x /usr/local/bin/kubectl
If you prefer not to copy kubectl, you need to ensure the tool is in your path:
# OS X export PATH=<path/to/kubernetes-directory>/platforms/darwin/amd64:$PATH # Linux export PATH=<path/to/kubernetes-directory>/platforms/linux/amd64:$PATH
In order for kubectl to find and access the Kubernetes cluster, it needs a kubeconfig file, which is created automatically when creating a cluster using kube-up.sh (see the getting started guides for more about creating clusters). If you need access to a cluster you didn’t create, see the Sharing Cluster Access document.
By default, kubectl configuration lives at
Check that kubectl is properly configured by getting the cluster state:
$ kubectl cluster-info
If you see a url response, you are ready to go.
