Using kubectl and YAML

kubectl is the officially supported command-line tool for accessing the Kubernetes API. It can be installed on Linux, macOS, or Windows.

Setting up kubectl and kubeconfig

To install the newest release of kubectl, you can use the installation instructions at https://kubernetes.io/docs/tasks/tools/install-kubectl/.

Once kubectl is installed, it needs to be set up to authenticate with one or more clusters. This is done using the kubeconfig file, which looks like this:

Example-kubeconfig

kind: Config
preferences: {}
clusters:
- cluster:
    certificate-authority: fake-ca-file
    server: https://1.2.3.4
  name: development
users:

  user:

    username: alex
