This repository hosts the kubernetes.core
(formerly known as community.kubernetes
) Ansible Collection.
The collection includes a variety of Ansible content to help automate the management of applications in Kubernetes and OpenShift clusters, as well as the provisioning and maintenance of clusters themselves.
-
Join the Ansible forum:
- Get Help: get help or help others.
- Posts tagged with 'kubernetes': subscribe to participate in collection-related conversations.
- Social Spaces: gather and interact with fellow enthusiasts.
- News & Announcements: track project-wide announcements including social events.
-
The Ansible Bullhorn newsletter: used to announce releases and important changes.
For more information about communication, see the Ansible communication guide.
This collection has been tested against following Ansible versions: >=2.15.0.
For collections that support Ansible 2.9, please ensure you update your network_os
to use the
fully qualified collection name (for example, cisco.ios.ios
).
Plugins and modules within a collection may be tested with only specific Ansible versions.
A collection may contain metadata that identifies these versions.
PEP440 is the schema used to describe the versions of Ansible.
- Collection supports 3.9+
Note: Python2 is deprecated from 1st January 2020. Please switch to Python3.
This collection supports Kubernetes versions >= 1.24.

Before using the Kubernetes collection, you need to install it with the Ansible Galaxy CLI:
ansible-galaxy collection install kubernetes.core
You can also include it in a requirements.yml
file and install it via ansible-galaxy collection install -r requirements.yml
, using the format:
---
collections:
- name: kubernetes.core
version: 5.0.0
Content in this collection requires the Kubernetes Python client to interact with Kubernetes' APIs. You can install it with:
pip3 install kubernetes
It's preferable to use content in this collection using their Fully Qualified Collection Namespace (FQCN), for example kubernetes.core.k8s_info
:
---
- hosts: localhost
gather_facts: false
connection: local
tasks:
- name: Ensure the myapp Namespace exists.
kubernetes.core.k8s:
api_version: v1
kind: Namespace
name: myapp
state: present
- name: Ensure the myapp Service exists in the myapp Namespace.
kubernetes.core.k8s:
state: present
definition:
apiVersion: v1
kind: Service
metadata:
name: myapp
namespace: myapp
spec:
type: LoadBalancer
ports:
- port: 8080
targetPort: 8080
selector:
app: myapp
- name: Get a list of all Services in the myapp namespace.
kubernetes.core.k8s_info:
kind: Service
namespace: myapp
register: myapp_services
- name: Display number of Services in the myapp namespace.
debug:
var: myapp_services.resources | count
If upgrading older playbooks which were built prior to Ansible 2.10 and this collection's existence, you can also define collections
in your play and refer to this collection's modules as you did in Ansible 2.9 and below, as in this example:
---
- hosts: localhost
gather_facts: false
connection: local
collections:
- kubernetes.core
tasks:
- name: Ensure the myapp Namespace exists.
k8s:
api_version: v1
kind: Namespace
name: myapp
state: present
For documentation on how to use individual modules and other content included in this collection, please see the links in the 'Included content' section earlier in this README.
The kubernetes.core
collection supports Ansible Turbo mode as a tech preview via the cloud.common
collection. By default, this feature is disabled. To enable Turbo mode for modules, set the environment variable ENABLE_TURBO_MODE=1
on the managed node. For example:
---
- hosts: remote
environment:
ENABLE_TURBO_MODE: 1
tasks:
...
To enable Turbo mode for k8s lookup plugin, set the environment variable ENABLE_TURBO_MODE=1
on the managed node. This is not working when
defined in the playbook using environment
keyword as above, you must set it using export ENABLE_TURBO_MODE=1
.
Please read more about Ansible Turbo mode - here.
If you want to develop new content for this collection or improve what's already here, the easiest way to work on the collection is to clone it into one of the configured COLLECTIONS_PATHS
, and work on it there.
See Contributing to kubernetes.core.
The tests
directory contains configuration for running sanity and integration tests using ansible-test
.
You can run the collection's test suites with the commands:
make test-sanity
make test-integration
make test-unit
There are also integration tests in the molecule
directory which are meant to be run against a local Kubernetes cluster, e.g. using KinD or Minikube. To setup a local cluster using KinD and run Molecule:
kind create cluster
make test-molecule
Releases are automatically built and pushed to Ansible Galaxy for any new tag. Before tagging a release, make sure to do the following:
- Update the version in the following places:
- The
version
ingalaxy.yml
- This README's
requirements.yml
example - The
VERSION
inMakefile
- The
- Update the CHANGELOG:
- Make sure you have
antsibull-changelog
installed. - Make sure there are fragments for all known changes in
changelogs/fragments
. - Run
antsibull-changelog release
.
- Make sure you have
- Commit the changes and create a PR with the changes. Wait for tests to pass, then merge it once they have.
- Tag the version in Git and push to GitHub.
After the version is published, verify it exists on the Kubernetes Collection Galaxy page.
The process for uploading a supported release to Automation Hub is documented separately.
We announce releases and important changes through Ansible's The Bullhorn newsletter. Be sure you are subscribed.
We take part in the global quarterly Ansible Contributor Summit virtually or in-person. Track The Bullhorn newsletter and join us.
