pykube 0.12.0

Features

• HTTP interface using requests using kubeconfig for authentication

• Python native querying of Kubernetes API objects

Installation

To install pykube, use pip:

pip install pykube

Usage

Query for all ready pods in a custom namespace:

import operator
import pykube

api = pykube.HTTPClient(pykube.KubeConfig.from_file("/Users/<username>/.kube/config"))
pods = pykube.Pod.objects(api).filter(namespace="gondor-system")
ready_pods = filter(operator.attrgetter("ready"), pods)

Selector query:

pods = pykube.Pod.objects(api).filter(
    namespace="gondor-system",
    selector={"gondor.io/name__in": {"api-web", "api-worker"}},
)

Create a ReplicationController:

obj = {
    "apiVersion": "v1",
    "kind": "ReplicationController",
    "metadata": {
        "name": "my-rc",
        "namespace": "gondor-system"
    },
    "spec": {
        "replicas": 3,
        "selector": {
            "app": "nginx"
        },
        "template": {
            "metadata": {
                "labels": {
                    "app": "nginx"
                }
            },
            "spec": {
                "containers": [
                    {
                        "name": "nginx",
                        "image": "nginx",
                        "ports": [
                            {"containerPort": 80}
                        ]
                    }
                ]
            }
        }
    }
}
pykube.ReplicationController(api, obj).create()

Delete a ReplicationController:

obj = {
    "apiVersion": "v1",
    "kind": "ReplicationController",
    "metadata": {
        "name": "my-rc",
        "namespace": "gondor-system"
    }
}
pykube.ReplicationController(api, obj).delete()
