dictionary

added in kubernetes.core 1.2.0

Configure behavior when deleting an object.

Specify condition that must be met for delete to proceed.

resourceVersion

string

Specify the resource version of the target object.

uid

string

Specify the UID of the target object.

propagationPolicy

If not specified, the default policy for the object type will be used. This may vary across object types.

Choices:

  • "Foreground"

  • "Background"

  • "Orphan"

force

boolean

If set to yes, and state is present, an existing object will be replaced.

Choices:

  • false ← (default)

  • true

generate_name

string

Specify the basis of the VirtualMachine name and random characters will be added automatically on server to generate a unique name.

Only used when state=present.

mutually exclusive with name.

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.

instancetype

dictionary

Specify the instancetype matcher of the VirtualMachine.

Only used when state=present.

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.

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.

labels

dictionary

Specify labels to set on the VirtualMachine.

name

string

Specify the name of the VirtualMachine.

This option is ignored when state is not set to present.

mutually exclusive with generate_name.

namespace

string / required

Specify the namespace of the VirtualMachine.

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”

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

preference

dictionary

Specify the preference matcher of the VirtualMachine.

Only used when state=present.

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

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.

running

boolean

Specify whether the VirtualMachine should be running.

Choices:

  • false

  • true ← (default)

spec

dictionary

state

string

Determines if an object should be created, patched, or deleted. When set to present, an object will be created, if it does not already exist. If set to absent, an existing object will be deleted. If set to present, an existing object will be patched, if its attributes differ from those specified using resource_definition or src.

Choices:

  • "absent"

  • "present" ← (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 the VirtualMachine to end up in the ready state.

Choices:

  • false ← (default)

  • true

wait_sleep

integer

Number of seconds to sleep between checks.

Ignored if wait is not set.

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.
