Kubernetes CLI (kubectl) wrapper in Python with OAuth token authentication.

This wrapper script zkubectl serves as a drop-in replacement for the kubectl binary:

• it downloads the current kubectl binary from Google
• it generates a new ~/.kube/config with an OAuth Bearer token acquired via zign.
• it passes through commands to the kubectl binary

Requires Python 3.4+.

$ sudo pip3 install --upgrade zalando-kubectl

You can directly login to a known Kubernetes API server endpoint:

$ zkubectl login https://my-api-server.example.org
$ zkubectl cluster-info

You can also configure a Cluster Registry to look up clusters by ID:

$ zkubectl configure --cluster-registry=https://cluster-registry.example.org
$ zkubectl login my-cluster-id

The Cluster Registry needs to provide the following HTTP API for this to work:

$ curl -H "Authorization: Bearer $(zign tok)" https://cluster-registry.example.org/kubernetes-clusters/my-cluster-id
{
    "api_server_url": "https://my-api-server.example.org"
}

There is an additional convenience command to open the Kubernetes Dashboard web UI in the browser:

$ zkubectl dashboard
