module: k8s

short_description: Manage Kubernetes (K8s) objects

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

description:
  - Use the Kubernetes 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 M(kubernetes.core.k8s_info) module to obtain a list of items about an object of type C(kind)
  - Authenticate using either a config file, certificates, password or token.
  - Supports check mode.

extends_documentation_fragment:
  - kubernetes.core.k8s_name_options
  - kubernetes.core.k8s_resource_options
  - kubernetes.core.k8s_auth_options
  - kubernetes.core.k8s_wait_options
  - kubernetes.core.k8s_delete_options

options:
  state:
    description:
    - Determines if an object should be created, patched, or deleted. When set to C(present), an object will be
      created, if it does not already exist. If set to C(absent), an existing object will be deleted. If set to
      C(present), an existing object will be patched, if its attributes differ from those specified using
      I(resource_definition) or I(src).
    - C(patched) state is an existing resource that has a given patch applied. If the resource doesn't exist, silently skip it (do not raise an error).
    type: str
    default: present
    choices: [ absent, present, patched ]
  force:
    description:
    - If set to C(yes), and I(state) is C(present), an existing object will be replaced.
    type: bool
    default: no
  merge_type:
    description:
    - Whether to override the default patch merge approach with a specific type. By default, the strategic
      merge will typically be used.
    - For example, Custom Resource Definitions typically aren't updatable by the usual strategic merge. You may
      want to use C(merge) if you see "strategic merge patch format is not supported"
    - See U(https://kubernetes.io/docs/tasks/run-application/update-api-object-kubectl-patch/#use-a-json-merge-patch-to-update-a-deployment)
    - If more than one C(merge_type) is given, the merge_types will be tried in order. This defaults to
      C(['strategic-merge', 'merge']), which is ideal for using the same parameters on resource kinds that
      combine Custom Resources and built-in resources.
    - mutually exclusive with C(apply)
    - I(merge_type=json) is deprecated and will be removed in version 3.0.0. Please use M(kubernetes.core.k8s_json_patch) instead.
    choices:
    - json
    - merge
    - strategic-merge
    type: list
    elements: str
  validate:
    description:
      - how (if at all) to validate the resource definition against the kubernetes schema.
        Requires the kubernetes-validate python module.
    suboptions:
      fail_on_error:
        description: whether to fail on validation errors.
        type: bool
      version:
        description: version of Kubernetes to validate against. defaults to Kubernetes server version

        description: whether to fail when passing unexpected properties
        default: True
        type: bool
    type: dict
  append_hash:
    description:
    - Whether to append a hash to a resource name for immutability purposes
    - Applies only to ConfigMap and Secret resources
    - The parameter will be silently ignored for other resource kinds
    - The full definition of an object is needed to generate the hash - this means that deleting an object created with append_hash
      will only work if the same object is passed with state=absent (alternatively, just use state=absent with the name including
      the generated hash and append_hash=no)
    default: False
    type: bool
  apply:
    description:
    - C(apply) compares the desired resource definition with the previously supplied resource definition,
      ignoring properties that are automatically generated
    - C(apply) works better with Services than 'force=yes'
    - mutually exclusive with C(merge_type)
    default: False
    type: bool
  template:
    description:
    - Provide a valid YAML template definition file for an object when creating or updating.
    - Value can be provided as string or dictionary.
    - The parameter accepts multiple template files. Added in version 2.0.0.
    - Mutually exclusive with C(src) and C(resource_definition).
    - Template files needs to be present on the Ansible Controller's file system.
    - Additional parameters can be specified using dictionary.
    - 'Valid additional parameters - '
    - 'C(newline_sequence) (str): Specify the newline sequence to use for templating files.
      valid choices are "\n", "\r", "\r\n". Default value "\n".'
    - 'C(block_start_string) (str): The string marking the beginning of a block.
      Default value "{%".'
    - 'C(block_end_string) (str): The string marking the end of a block.
      Default value "%}".'
    - 'C(variable_start_string) (str): The string marking the beginning of a print statement.
      Default value "{{".'
    - 'C(variable_end_string) (str): The string marking the end of a print statement.
      Default value "}}".'
    - 'C(trim_blocks) (bool): Determine when newlines should be removed from blocks. When set to C(yes) the first newline
       after a block is removed (block, not variable tag!). Default value is true.'
    - 'C(lstrip_blocks) (bool): Determine when leading spaces and tabs should be stripped.
      When set to C(yes) leading spaces and tabs are stripped from the start of a line to a block.
      This functionality requires Jinja 2.7 or newer. Default value is false.'
    type: raw
  continue_on_error:
    description:
    - Whether to continue on creation/deletion errors when multiple resources are defined.
    - This has no effect on the validation step which is controlled by the C(validate.fail_on_error) parameter.
    type: bool
    default: False
    version_added: 2.0.0
  label_selectors:
    description:
    - Selector (label query) to filter on.
    type: list
    elements: str
    version_added: 2.2.0
  generate_name:
    description:
    - Use to specify the basis of an object name and random characters will be added automatically on server to generate a unique name.
    - This option is ignored when I(state) is not set to C(present) or when I(apply) is set to C(yes).
    - If I(resource definition) is provided, the I(metadata.generateName) value from the I(resource_definition)
      will override this option.
    - If I(resource definition) is provided, and contains I(metadata.name), this option is ignored.
    - mutually exclusive with C(name).
    type: str
    version_added: 2.3.0
  server_side_apply:
    description:
    - When this option is set, apply runs in the server instead of the client.
    - Ignored if C(apply) is not set or is set to False.
    - This option requires "kubernetes >= 19.15.0".
    type: dict
    version_added: 2.3.0
    suboptions:
      field_manager:
        type: str

        - Name of the manager used to track field ownership.
        required: True
      force_conflicts:
        description:
        - A conflict is a special status error that occurs when an Server Side Apply operation tries to change a field,
          which another user also claims to manage.
        - When set to True, server-side apply will force the changes against conflicts.
        type: bool
        default: False
