k8s_raw - Manage Kubernetes (K8s) objects
New in version 2.5.
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.
- Access to the full range of K8s APIs.
- Authenticate using either a config file, certificates, password or token.
- Supports check mode.
Requirements
The below requirements are needed on the host that executes this module.
- python >= 2.7
- openshift == 0.4.3
- PyYAML >= 3.11
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
api_key | Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable. | |
api_version | Default: v1 | Use to specify the API version. Use to create, delete, or discover an object without providing a full resource definition. Use in conjunction with kind, name, and namespace to identify a specific object. If resource definition is provided, the apiVersion from the resource_definition will override this option. aliases: api, version |
cert_file | Path to a certificate used to authenticate with the API. Can also be specified via K8S_AUTH_CERT_FILE environment variable. | |
context | The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable. | |
force |
| If set to True , and state is present , an existing object will be replaced. |
host | Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable. | |
key_file | Path to a key file used to authenticate with the API. Can also be specified via K8S_AUTH_HOST environment variable. | |
kind | Use to specify an object model. Use to create, delete, or discover an object without providing a full resource definition. Use in conjunction with api_version, name, and namespace to identify a specific object. If resource definition is provided, the kind from the resource_definition will override this option. | |
kubeconfig | Path to an existing Kubernetes config file. If not provided, and no other connection options are provided, the openshift client will attempt to load the default configuration file from ~/.kube/config.json. Can also be specified via K8S_AUTH_KUBECONFIG environment variable. | |
name | Use to specify an object name. Use to create, delete, or discover an object without providing a full resource definition. Use in conjunction with api_version, kind and namespace to identify a specific object. If resource definition is provided, the metadata.name value from the resource_definition will override this option. | |
namespace | Use to specify an object namespace. Useful when creating, deleting, or discovering an object without providing a full resource definition. Use in conjunction with api_version, kind, and name to identify a specfic object. If resource definition is provided, the metadata.namespace value from the resource_definition will override this option. | |
password | Provide a password for authenticating with the API. Can also be specified via K8S_AUTH_PASSWORD environment variable. | |
resource_definition | Provide a valid YAML definition for an object when creating or updating. NOTE: kind, api_version, name, and namespace will be overwritten by corresponding values found in the provided resource_definition. aliases: definition, inline | |
src | Provide a path to a file containing a valid YAML definition of an object to be created or updated. Mutually exclusive with resource_definition. NOTE: kind, api_version, name, and namespace will be overwritten by corresponding values found in the configuration read in from the src file. Reads from the local file system. To read from the Ansible controller's file system, use the file lookup plugin or template lookup plugin, combined with the from_yaml filter, and pass the result to resource_definition. See Examples below. | |
ssl_ca_cert | Path to a CA certificate used to authenticate with the API. Can also be specified via K8S_AUTH_SSL_CA_CERT environment variable. | |
state |
| Determines if an object should be created, patched, or deleted. When set to present , an object will be created, if it does not already exist. If set to absent , an existing object will be deleted. If set to present , an existing object will be patched, if its attributes differ from those specified using resource_definition or src. |
username | Provide a username for authenticating with the API. Can also be specified via K8S_AUTH_USERNAME environment variable. | |
verify_ssl |
| Whether or not to verify the API server's SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable. |
Notes
Note
- 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

Return Values
Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description | |
---|---|---|---|
result complex | success | The created, patched, or otherwise present object. Will be empty in the case of a deletion. | |
status complex | success | Current status details for the object. | |
kind str | success | Represents the REST resource this object represents. | |
items list | when resource is a List | Returned only when the kind is a List type resource. Contains a set of objects. | |
spec complex | success | Specific attributes of the object. Will vary based on the api_version and kind. | |
api_version str | success | The versioned schema of this representation of an object. | |
metadata complex | success | Standard object metadata. Includes name, namespace, annotations, labels, etc. |
Status
This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
