Removes references to the specified roles, clusterroles, users, and groups

Version added: 2.2.0

Synopsis

  • This module allow administrators to remove references to the specified roles, clusterroles, users, and groups.
  • Analogous to oc adm prune auth.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 3.6
  • kubernetes >= 12.0.0

Parameters

Parameter Choices/Defaults Comments
api_key
string
Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable.
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: ssl_ca_cert
client_cert
path
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
path
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
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 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 2.3.0
Username to impersonate for the operation.
Can also be specified via K8S_AUTH_IMPERSONATE_USER environment.
kubeconfig
raw
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.
Multiple Kubernetes config file can be provided using separator ';' for Windows platform or ':' for others platforms.
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.
label_selectors
list / elements=string
Selector (label query) to filter on.
Mutually exclusive with option name.
name
string
Use to specify an object name to remove.
Mutually exclusive with option label_selectors.
If neither name nor label_selectors are specified, prune all resources in the namespace.
namespace
string
Use to specify an object namespace.
Ignored when resource is set to clusterroles.
no_proxy
string
added in 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"
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
    Choices:
  • no
  • yes
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: kubernetes-client/python-base#169
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 2.0.0
The Header used for the HTTP proxy.
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
string / required
    Choices:
  • roles
  • clusterroles
  • users
  • groups
The specified resource to remove.
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
boolean
    Choices:
  • no
  • yes
Whether or not to verify the API server's SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable.

aliases: verify_ssl

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.
