k8s_info – Describe Kubernetes (K8s) objects

New in version 2.7.

Synopsis

• Use the OpenShift Python client to perform read operations on K8s objects.

• Access to the full range of K8s APIs.

• Authenticate using either a config file, certificates, password or token.

• Supports check mode.

• This module was called k8s_facts before Ansible 2.9. The usage did not change.

Aliases: k8s_facts

Requirements

The below requirements are needed on the host that executes this module.

• python >= 2.7

• openshift >= 0.6

• PyYAML >= 3.11

Parameters

Parameter	Choices/Defaults	Comments
api_key string		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. in conjunction with kind, name, and namespace to identify a specific object. aliases: api, version
ca_cert path		Path to a CA certificate used to authenticate with the API. The full certificate chain must be provided to avoid certificate validation errors. Can also be specified via K8S_AUTH_SSL_CA_CERT environment variable. aliases: ssl_ca_cert
client_cert path		Path to a certificate used to authenticate with the API. Can also be specified via K8S_AUTH_CERT_FILE environment variable. aliases: cert_file
client_key path		Path to a key file used to authenticate with the API. Can also be specified via K8S_AUTH_KEY_FILE environment variable. aliases: key_file
context string		The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable.
field_selectors -		List of field selectors to use to filter results
host string		Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.
kind - / required		Use to specify an object model. Use in conjunction with api_version, name, and namespace to identify a specific object.
kubeconfig path		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.
label_selectors -		List of label selectors to use to filter results
name -		Use to specify an object name. Use in conjunction with api_version, kind and namespace to identify a specific object.
namespace -		Use to specify an object namespace. Use in conjunction with api_version, kind, and name to identify a specific object.
password string		Provide a password for authenticating with the API. Can also be specified via K8S_AUTH_PASSWORD environment variable. Please read the description of the username option for a discussion of when this option is applicable.
proxy - added in 2.9		The URL of an HTTP proxy to use for the connection. Can also be specified via K8S_AUTH_PROXY environment variable. Please note that this module does not pick up typical proxy settings from the environment (e.g. HTTP_PROXY).
username string		Provide a username for authenticating with the API. Can also be specified via K8S_AUTH_USERNAME environment variable. Please note that this only works with clusters configured to use HTTP Basic Auth. If your cluster has a different form of authentication (e.g. OAuth2 in OpenShift), this option will not work as expected and you should look into the k8s_auth module, as that might do what you need.
validate_certs boolean	Choices: no yes	Whether or not to verify the API server's SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable. aliases: verify_ssl

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

• To avoid SSL certificate validation errors when validate_certs is True, the full certificate chain for the API server must be provided via ca_cert or in the kubeconfig file.

Examples

- name: Get an existing Service object
  k8s_info:
    api_version: v1
    kind: Service
    name: web
    namespace: testing
  register: web_service

- name: Get a list of all service objects
  k8s_info:
    api_version: v1
    kind: Service
    namespace: testing
  register: service_list

- name: Get a list of all pods from any namespace
  k8s_info:
    kind: Pod
  register: pod_list

- name: Search for all Pods labelled app=web
  k8s_info:
    kind: Pod
    label_selectors:
      - app = web
      - tier in (dev, test)

- name: Search for all running pods
  k8s_info:
    kind: Pod
    field_selectors:
      - status.phase=Running
