short_description: Query the K8s API

author:
      - Chris Houseknecht (@chouseknecht)
      - Fabian von Feilitzsch (@fabianvf)

description:
      - Uses the Kubernetes Python client to fetch a specific object by name, all matching objects within a
        namespace, or all matching objects for all namespaces, as well as information about the cluster.
      - Provides access the full range of K8s APIs.
      - Enables authentication via config file, certificates, password or token.
    notes:
      - While querying, please use C(query) or C(lookup) format with C(wantlist=True) to provide an easier and more
        consistent interface. For more details, see
        U(https://docs.ansible.com/ansible/latest/plugins/lookup.html#forcing-lookups-to-return-lists-query-and-wantlist-true).
    options:
      cluster_info:
        description:
        - Use to specify the type of cluster information you are attempting to retrieve. Will take priority
          over all the other options.
      api_version:
        description:
        - Use to specify the API version. If I(resource definition) is provided, the I(apiVersion) from the
          I(resource_definition) will override this option.
        default: v1
      kind:
        description:
        - Use to specify an object model. If I(resource definition) is provided, the I(kind) from a
          I(resource_definition) will override this option.
        required: true
      resource_name:
        description:
        - Fetch a specific object by name. If I(resource definition) is provided, the I(metadata.name) value
          from the I(resource_definition) will override this option.
      namespace:
        description:
        - Limit the objects returned to a specific namespace. If I(resource definition) is provided, the
          I(metadata.namespace) value from the I(resource_definition) will override this option.
      label_selector:
        description:
        - Additional labels to include in the query. Ignored when I(resource_name) is provided.
      field_selector:
        description:
        - Specific fields on which to query. Ignored when I(resource_name) is provided.
      resource_definition:
        description:
        - "Provide a YAML configuration for an object. NOTE: I(kind), I(api_version), I(resource_name),
          and I(namespace) will be overwritten by corresponding values found in the provided I(resource_definition)."
      src:
        description:
        - "Provide a path to a file containing a valid YAML definition of an object dated. Mutually
          exclusive with I(resource_definition). NOTE: I(kind), I(api_version), I(resource_name), and I(namespace)
          will be overwritten by corresponding values found in the configuration read in from the I(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
          I(resource_definition). See Examples below.
      host:
        description:
        - Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.
      api_key:
        description:
        - Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable.
      kubeconfig:
        description:
        - Path to an existing Kubernetes config file. If not provided, and no other connection
          options are provided, the Kubernetes client will attempt to load the default
          configuration file from I(~/.kube/config). Can also be specified via K8S_AUTH_KUBECONFIG environment
          variable.
      context:
        description:
        - The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment
          variable.
      username:
        description:
        - Provide a username for authenticating with the API. Can also be specified via K8S_AUTH_USERNAME environment
          variable.
      password:
        description:
        - Provide a password for authenticating with the API. Can also be specified via K8S_AUTH_PASSWORD environment
          variable.
      client_cert:
        description:
        - 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:
        description:
        - 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 ]
      ca_cert:
        description:
        - Path to a CA certificate used to authenticate with the API. Can also be specified via K8S_AUTH_SSL_CA_CERT
          environment variable.
        aliases: [ ssl_ca_cert ]
      validate_certs:
        description:
        - Whether or not to verify the API server's SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL
          environment variable.
        type: bool
