module: k8s

short_description: Manage Kubernetes (K8s) objects

version_added: "2.6"

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

description:
  - 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 M(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:
  - k8s_state_options
  - k8s_name_options
  - k8s_resource_options
  - k8s_auth_options

notes:
  - 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.

options:
  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)
    - Requires openshift >= 0.6.2
    - If more than one merge_type is given, the merge_types will be tried in order
    - If openshift >= 0.6.2, 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. For openshift < 0.6.2, the default
      is simply C(strategic-merge).
    - mutually exclusive with C(apply)
    choices:
    - json
    - merge
    - strategic-merge
    type: list
    version_added: "2.7"
  wait:
    description:
    - Whether to wait for certain resource kinds to end up in the desired state. By default the module exits once Kubernetes has
      received the request
    - Implemented for C(state=present) for C(Deployment), C(DaemonSet) and C(Pod), and for C(state=absent) for all resource kinds.
    - For resource kinds without an implementation, C(wait) returns immediately unless C(wait_condition) is set.
    default: no
    type: bool
    version_added: "2.8"
  wait_sleep:
    description:
    - Number of seconds to sleep between checks.
    default: 5
    version_added: "2.9"
  wait_timeout:
    description:
    - How long in seconds to wait for the resource to end up in the desired state. Ignored if C(wait) is not set.
    default: 120
    version_added: "2.8"
  wait_condition:
    description:
    - Specifies a custom condition on the status to wait for. Ignored if C(wait) is not set or is set to False.
    suboptions:
      type:
        description:
        - The type of condition to wait for. For example, the C(Pod) resource will set the C(Ready) condition (among others)
        - Required if you are specifying a C(wait_condition). If left empty, the C(wait_condition) field will be ignored.
        - The possible types for a condition are specific to each resource type in Kubernetes. See the API documentation of the status field
          for a given resource to see possible choices.
      status:
        description:
        - The value of the status field in your desired condition.
        - For example, if a C(Deployment) is paused, the C(Progressing) C(type) will have the C(Unknown) status.
        choices:
        - True
        - False
        - Unknown
      reason:
        description:
        - The value of the reason field in your desired condition
        - For example, if a C(Deployment) is paused, The C(Progressing) c(type) will have the C(DeploymentPaused) reason.
        - The possible reasons in a condition are specific to each resource type in Kubernetes. See the API documentation of the status field
          for a given resource to see possible choices.
    version_added: "2.8"
  validate:
    description:
      - how (if at all) to validate the resource definition against the kubernetes schema.
        Requires the kubernetes-validate python module and openshift >= 0.8.0
    suboptions:
      fail_on_error:
        description: whether to fail on validation errors.
        required: yes
        type: bool
      version:
        description: version of Kubernetes to validate against. defaults to Kubernetes server version
      strict:
        description: whether to fail when passing unexpected properties
        default: no
        type: bool
    version_added: "2.8"
  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)
    - Requires openshift >= 0.7.2
    type: bool
    version_added: "2.8"
  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'
    - Requires openshift >= 0.9.2
    - mutually exclusive with C(merge_type)
    type: bool
    version_added: "2.9"

requirements:
  - "python >= 2.7"
  - "openshift >= 0.6"
  - "PyYAML >= 3.11"
