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
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)
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'
- mutually exclusive with C(merge_type)
type: bool
version_added: "2.9"
requirements:
- "python >= 2.7"
- "openshift >= 0.6"
- "PyYAML >= 3.11"
