string

The name of a context found in the config file.

Can also be specified via K8S_AUTH_CONTEXT environment variable.

data_volume_templates

list / elements=dictionary

Specify the DataVolume templates of the VirtualMachine.

See https://kubevirt.io/api-reference/main/definitions.html#_v1_datavolumetemplatespec

delete_options

dictionary

Configure behavior when deleting an object.

Only used when state=absent.

preconditions

dictionary

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

string

Use to control how dependent objects are deleted.

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 force=yes, and state=present is set, 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 the cluster 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

Group(s) to impersonate for the operation.

Can also be specified via K8S_AUTH_IMPERSONATE_GROUPS environment variable, e.g. Group1,Group2.

impersonate_user

string

Username to impersonate for the operation.

Can also be specified via K8S_AUTH_IMPERSONATE_USER environment variable.

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=present is not set.

Mutually exclusive with generate_name.

namespace

string / required

Specify the namespace of the VirtualMachine.

no_proxy

string

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.

Disabled by default.

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

basic_auth

string

Colon-separated username:password for basic authentication header.

Can also be specified via K8S_AUTH_PROXY_HEADERS_BASIC_AUTH environment variable.

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 variable.

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 variable.

running

boolean

Specify whether the VirtualMachine should be running or not.

Choices:

  • false

  • true ← (default)

spec

dictionary

state

string

Determines if an object should be created, patched, or deleted.

When set to state=present, an object will be created, if it does not already exist.

If set to state=absent, an existing object will be deleted.

If set to state=present, an existing object will be patched, if its attributes differ from those specified.

Choices:

  • "absent"

  • "present" ← (default)

username

string

Provide a username for authenticating with the API.

Can also be specified via K8S_AUTH_USERNAME environment variable.

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 ready state.

Ignored if wait is not set.

Default: 120
