Parameters

Parameter

Comments

api_key

string

Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable.

ca_cert

aliases: ssl_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: cert_file

path

Path to a certificate used to authenticate with the API. Can also be specified via K8S_AUTH_CERT_FILE environment variable.

client_key

aliases: key_file

path

Path to a key file used to authenticate with the API. Can also be specified via K8S_AUTH_KEY_FILE environment variable.

context

string

The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable.

host

string

Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.

impersonate_groups

list / elements=string

added in kubernetes.core 2.3.0

Group(s) to impersonate for the operation.

Can also be specified via K8S_AUTH_IMPERSONATE_GROUPS environment. Example: Group1,Group2

impersonate_user

string

added in kubernetes.core 2.3.0

Username to impersonate for the operation.

Can also be specified via K8S_AUTH_IMPERSONATE_USER environment.

kubeconfig

any

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 ~/.kube/config. Can also be specified via K8S_AUTH_KUBECONFIG environment variable.

The kubernetes configuration can be provided as dictionary. This feature requires a python kubernetes client version >= 17.17.0. Added in version 2.2.0.

name

string

The name of the Template to process.

The Template must be present in the cluster.

When provided, namespace is required.

Mutually exclusive with resource_definition or src

namespace

string

The namespace that the template can be found in.

namespace_target

string

The namespace that resources should be created, updated, or deleted in.

Only used when state is present or absent.

no_proxy

string

added in kubernetes.core 2.3.0

The comma separated list of hosts/domains/IP/CIDR that shouldn’t go through proxy. Can also be specified via K8S_AUTH_NO_PROXY environment variable.

Please note that this module does not pick up typical proxy settings from the environment (e.g. NO_PROXY).

This feature requires kubernetes>=19.15.0. When kubernetes library is less than 19.15.0, it fails even no_proxy set in correct.

example value is “localhost,.local,.example.com,127.0.0.1,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16”

parameter_file

string

A path to a file containing template parameter values to override/set values in the Template.

Corresponds to the `–param-file` argument to oc process.

parameters

dictionary

A set of key: value pairs that will be used to set/override values in the Template.

Corresponds to the `–param` argument to oc process.

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.

persist_config

boolean

Whether or not to save the kube config refresh tokens. Can also be specified via K8S_AUTH_PERSIST_CONFIG environment variable.

When the k8s context is using a user credentials with refresh tokens (like oidc or gke/gcloud auth), the token is refreshed by the k8s python client library but not saved by default. So the old refresh token can expire and the next auth might fail. Setting this flag to true will tell the k8s python client to save the new refresh token to the kube config file.

Default to false.

Please note that the current version of the k8s python client library does not support setting this flag to True yet.

The fix for this k8s python library is here: https://github.com/kubernetes-client/python-base/pull/169

Choices:

  • false

  • true

proxy

string

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).

proxy_headers

dictionary

added in kubernetes.core 2.0.0

The Header used for the HTTP proxy.

Documentation can be found here https://urllib3.readthedocs.io/en/latest/reference/urllib3.util.html?highlight%3Dproxy_headers#urllib3.util.make_headers.

basic_auth

string

Colon-separated username:password for basic authentication header.

Can also be specified via K8S_AUTH_PROXY_HEADERS_BASIC_AUTH environment.

proxy_basic_auth

string

Colon-separated username:password for proxy basic authentication header.

Can also be specified via K8S_AUTH_PROXY_HEADERS_PROXY_BASIC_AUTH environment.

user_agent

string

String representing the user-agent you want, such as foo/1.0.

Can also be specified via K8S_AUTH_PROXY_HEADERS_USER_AGENT environment.

resource_definition

aliases: definition, inline

string

Provide a valid YAML definition (either as a string, list, or dict) for an object when creating or updating.

NOTE: kind, api_version, name, and namespace will be overwritten by corresponding values found in the provided resource_definition.

src

path

Provide a path to a file containing a valid YAML definition of an object or objects to be created or updated. Mutually exclusive with resource_definition. NOTE: kind, api_version, name, and namespace will be overwritten by corresponding values found in the configuration read in from the src file.

Reads from the local file system. To read from the Ansible controller’s file system, including vaulted files, use the file lookup plugin or template lookup plugin, combined with the from_yaml filter, and pass the result to resource_definition. See Examples below.

Mutually exclusive with template in case of kubernetes.core.k8s module.

state

string

Determines what to do with the rendered Template.

The state rendered will render the Template based on the provided parameters, and return the rendered objects in the resources field. These can then be referenced in future tasks.

The state present will cause the resources in the rendered Template to be created if they do not already exist, and patched if they do.

The state absent will delete the resources in the rendered Template.

Choices:

  • "absent"

  • "present"

  • "rendered" ← (default)

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 community.okd.k8s_auth module, as that might do what you need.

validate_certs

aliases: verify_ssl

boolean

Whether or not to verify the API server’s SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable.

Choices:

  • false

  • true

wait

boolean

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 state=present for Deployment, DaemonSet and Pod, and for state=absent for all resource kinds.

For resource kinds without an implementation, wait returns immediately unless wait_condition is set.

Choices:

  • false ← (default)

  • true

wait_condition

dictionary

Specifies a custom condition on the status to wait for.

Ignored if wait is not set or is set to False.

reason

string

The value of the reason field in your desired condition

For example, if a Deployment is paused, The Progressing type will have the 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.

status

string

The value of the status field in your desired condition.

For example, if a Deployment is paused, the Progressing type will have the Unknown status.

Choices:

  • "True" ← (default)

  • "False"

  • "Unknown"

type

string

The type of condition to wait for.

For example, the Pod resource will set the Ready condition (among others).

Required if you are specifying a wait_condition.

If left empty, the 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.

wait_sleep

integer

Number of seconds to sleep between checks.

Default: 5

wait_timeout

integer

How long in seconds to wait for the resource to end up in the desired state.

Ignored if wait is not set.

Default: 120

Notes

Note

  • 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.
