Kubernetes Python Client

Python client for the kubernetes API.

Installation

From source:

git clone --recursive https://github.com/kubernetes-client/python.git
cd python
python -m pip install --upgrade .

From PyPI directly:

pip install kubernetes

Examples

list all pods:

from kubernetes import client, config

# Configs can be set in Configuration class directly or using helper utility
config.load_kube_config()

v1 = client.CoreV1Api()
print("Listing pods with their IPs:")
ret = v1.list_pod_for_all_namespaces(watch=False)
for i in ret.items:
    print("%s\t%s\t%s" % (i.status.pod_ip, i.metadata.namespace, i.metadata.name))

list all pods using asyncio:

import asyncio
from kubernetes.aio import client, config
from kubernetes.aio.client.api_client import ApiClient


async def main():
    # Configs can be set in Configuration class directly or using helper
    # utility. If no argument provided, the config will be loaded from
    # default location.
    await config.load_kube_config()

    # use the context manager to close http sessions automatically
    async with ApiClient() as api:

        v1 = client.CoreV1Api(api)
        print("Listing pods with their IPs:")
        ret = await v1.list_pod_for_all_namespaces()

        for i in ret.items:
            print(i.status.pod_ip, i.metadata.namespace, i.metadata.name)


if __name__ == '__main__':
    asyncio.run(main())

watch on namespace object:

from kubernetes import client, config, watch

# Configs can be set in Configuration class directly or using helper utility
config.load_kube_config()

v1 = client.CoreV1Api()
count = 10
w = watch.Watch()
for event in w.stream(v1.list_namespace, _request_timeout=60):
    print("Event: %s %s" % (event['type'], event['object'].metadata.name))
    count -= 1
    if not count:
        w.stop()

print("Ended.")

More examples can be found in examples folder. To run examples, run this command:

python -m examples.example1

(replace example1 with one of the filenames in the examples folder)

Documentation

All APIs and Models' documentation can be found at the Generated client's README file

Compatibility

client-python follows semver, so until the major version of client-python gets increased, your code will continue to work with explicitly supported versions of Kubernetes clusters.

See here for an explanation of why there is no v13-v16 release.

Key:

• ✓ Exactly the same features / API objects in both client-python and the Kubernetes version.
• + client-python has features or API objects that may not be present in the Kubernetes cluster, either due to that client-python has additional new API, or that the server has removed old API. However, everything they have in common (i.e., most APIs) will work. Please note that alpha APIs may vanish or change significantly in a single release.
• - The Kubernetes cluster has features the client-python library can't use, either due to the server has additional new API, or that client-python has removed old API. However, everything they share in common (i.e., most APIs) will work.

See the CHANGELOG for a detailed description of changes between client-python versions.
