community.kubernetes.k8s – Manage Kubernetes (K8s) objects¶
Note
This plugin is part of the community.kubernetes collection (version 1.1.1).
To install it use: ansible-galaxy collection install community.kubernetes.
To use it in a playbook, specify: community.kubernetes.k8s.
Synopsis¶
Use the OpenShift Python client to perform CRUD operations on K8s objects.
Pass the object definition from a source file or inline. See examples for reading files and using Jinja templates or vault-encrypted files.
Access to the full range of K8s APIs.
Use the community.kubernetes.k8s_info module to obtain a list of items about an object of type
kindAuthenticate using either a config file, certificates, password or token.
Supports check mode.
Note
This module has a corresponding action plugin.
Requirements¶
The below requirements are needed on the host that executes this module.
python >= 2.7
openshift >= 0.6
PyYAML >= 3.11
Parameters¶
Notes¶
Note
If your OpenShift Python library is not 0.9.0 or newer and you are trying to remove an item from an associative array/dictionary, for example a label or an annotation, you will need to explicitly set the value of the item to be removed to null. Simply deleting the entry in the dictionary will not remove it from openshift or kubernetes.
The OpenShift Python client wraps the K8s Python client, providing full access to all of the APIS and models available on both platforms. For API version details and additional information visit https://github.com/openshift/openshift-restclient-python
To avoid SSL certificate validation errors when
validate_certsis True, the full certificate chain for the API server must be provided viaca_certor in the kubeconfig file.
