kubevirt_pvc – Manage PVCs on Kubernetes

New in version 2.8.

Synopsis

Use Openshift Python SDK to manage PVCs on Kubernetes
Support Containerized Data Importer out of the box

Requirements

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

python >= 2.7
openshift >= 0.8.2

Parameters

Parameter	Choices/Defaults	Comments
access_modes list		Contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes
annotations dictionary		Annotations attached to this object. https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/
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
cdi_source dictionary		If data is to be copied onto the PVC using the Containerized Data Importer you can specify the source of the data (along with any additional configuration) as well as it's format. Valid source types are: blank, http, s3, registry, pvc and upload. The last one requires using the kubevirt_cdi_upload module to actually perform an upload. Source data format is specified using the optional content_type. Valid options are `kubevirt` (default; raw image) and `archive` (tar.gz). This uses the DataVolume source syntax: https://github.com/kubevirt/containerized-data-importer/blob/master/doc/datavolumes.md#https3registry-source
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.
force boolean	Choices: no ← yes	If set to `True`, and state is `present`, an existing object will be replaced.
host string		Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.
kubeconfig path		Path to an existing Kubernetes config file. If not provided, and no other connection options are provided, the openshift client will attempt to load the default configuration file from ~/.kube/config.json. Can also be specified via K8S_AUTH_KUBECONFIG environment variable.
labels dictionary		Labels attached to this object. https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/
merge_type list	Choices: json merge strategic-merge	Whether to override the default patch merge approach with a specific type. This defaults to `['strategic-merge', 'merge']`, which is ideal for using the same parameters on resource kinds that combine Custom Resources and built-in resources. See https://kubernetes.io/docs/tasks/run-application/update-api-object-kubectl-patch/#use-a-json-merge-patch-to-update-a-deployment If more than one merge_type is given, the merge_types will be tried in order
name string / required		Use to specify a PVC object name.
namespace string / required		Use to specify a PVC object namespace.
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.
resource_definition dictionary		A partial YAML definition of the PVC object being created/updated. Here you can define Kubernetes PVC Resource parameters not covered by this module's parameters. NOTE: resource_definition has lower priority than module parameters. If you try to define e.g. metadata.namespace here, that value will be ignored and namespace used instead. aliases: definition, inline
selector dictionary		A label query over volumes to consider for binding. https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/
size string		How much storage to allocate to the PVC. aliases: storage
state -	Choices: present ← absent	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 module options and resource_definition.
storage_class_name string		Name of the StorageClass required by the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1
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 `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
volume_mode string		This defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec. This is an alpha feature of kubernetes and may change in the future.
volume_name string		This is the binding reference to the PersistentVolume backing this claim.
wait boolean	Choices: no ← yes	If set, this module will wait for the PVC to become bound and CDI (if enabled) to finish its operation before returning. Used only if state set to `present`. Unless used in conjunction with cdi_source, this might result in a timeout, as clusters may be configured to not bind PVCs until first usage.
wait_timeout integer	Default: 300	Specifies how much time in seconds to wait for PVC creation to complete if wait option is enabled. Default value is reasonably high due to an expectation that CDI might take a while to finish its operation.

Notes

Note

The OpenShift Python client wraps the K8s Python client, providing full access to all of the APIS and models available on both platforms. For API version details and additional information visit https://github.com/openshift/openshift-restclient-python
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.
