Kel is an open source Platform as a Service (PaaS) from Eldarion, Inc. that makes it easy to manage web application deployment and hosting through the entire lifecycle from development through testing to production. It adds components and tools on top of Kubernetes that help developers manage their application infrastructure. Kel builds on Eldarion's 7+ years experience running one of the leading Python and Django PaaSes.

For more information about Kel, see kelproject.com, follow us on Twitter @projectkel, and join our Slack team.

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)

Access any attribute of the Kubernetes object:

pod = pykube.Pod.objects(api).filter(namespace="gondor-system").get(name="my-pod")
pod.obj["spec"]["containers"][0]["image"]

Selector query:

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

Watch query:

watch = pykube.Job.objects(api, namespace="gondor-system")
watch = watch.filter(field_selector={"metadata.name": "my-job"}).watch()

# watch is a generator:
for watch_event in watch:
    print(watch_event.type) # 'ADDED', 'DELETED', 'MODIFIED'
    print(watch_event.object) # pykube.Job object

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()

Check server version:

api = pykube.HTTPClient(pykube.KubeConfig.from_file("/Users/<username>/.kube/config"))
api.version

HTTPie

pykube can be used together with HTTPie for Kubernetes command line querying goodness. For example:

pip install httpie
http pykube://minikube/api/v1/services

The above example will construct an HTTP request to the cluster behind the minikube context and show you the response containing all services.
