- python >= 2.7

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
affinity dictionary added in 2.9 |  | Describes node affinity scheduling rules for the vm.
| hard dictionary |  | If the affinity requirements specified by this field are not met at scheduling time, the vm will not be scheduled onto the node. If the affinity requirements specified by this field cease to be met at some point during vm execution (e.g. due to a vm label update), the system may or may not try to eventually evict the vm from its node. When there are multiple elements, the lists of nodes corresponding to each `term` are intersected, i.e. all terms must be satisfied.
| soft dictionary |  | The scheduler will prefer to schedule vms to nodes that satisfy the affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding `weight` to the sum if the node has vms which matches the corresponding `term`; the nodes with the highest sum are the most preferred.
anti_affinity dictionary added in 2.9 |  | Describes vm anti-affinity scheduling rules e.g. avoid putting this vm in the same node, zone, etc. as some other vms.
| hard dictionary |  | If the anti-affinity requirements specified by this field are not met at scheduling time, the vm will not be scheduled onto the node. If the anti-affinity requirements specified by this field cease to be met at some point during vm execution (e.g. due to a vm label update), the system may or may not try to eventually evict the vm from its node. When there are multiple elements, the lists of nodes corresponding to each `term` are intersected, i.e. all terms must be satisfied.
| soft dictionary |  | The scheduler will prefer to schedule vms to nodes that satisfy the anti-affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling anti-affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding `weight` to the sum if the node has vms which matches the corresponding `term`; the nodes with the highest sum are the most preferred.
api_key string |  | Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable.
bootloader string |  | Specify the bootloader of the virtual machine. All virtual machines use BIOS by default for booting.
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
cloud_init_nocloud dictionary |  | Represents a cloud-init NoCloud user-data source. The NoCloud data will be added as a disk to the virtual machine. A proper cloud-init installation is required inside the guest. More information https://kubevirt.io/api-reference/master/definitions.html#_v1_cloudinitnocloudsource
context string |  | The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable.
cpu_cores integer |  | Number of CPU cores.
cpu_features list |  | List of dictionary to fine-tune features provided by the selected CPU model. Note: Policy attribute can either be omitted or contain one of the following policies: force, require, optional, disable, forbid. Note: In case a policy is omitted for a feature, it will default to require. More information about policies: https://libvirt.org/formatdomain.html#elementsCPU
cpu_limit integer |  | Is converted to its millicore value and multiplied by 100. The resulting value is the total amount of CPU time that a container can use every 100ms. A virtual machine cannot use more than its share of CPU time during this interval.
cpu_model string |  | CPU model. You can check list of available models here: https://github.com/libvirt/libvirt/blob/master/src/cpu_map/index.xml. Note: User can define default CPU model via as default-cpu-model in kubevirt-config ConfigMap, if not set host-model is used. Note: Be sure that node CPU model where you run a VM, has the same or higher CPU family. Note: If CPU model wasn't defined, the VM will have CPU model closest to one that used on the node where the VM is running.
cpu_shares integer |  | Specify CPU shares.
datavolumes list |  | DataVolumes are a way to automate importing virtual machine disks onto pvcs during the virtual machine's launch flow. Without using a DataVolume, users have to prepare a pvc with a disk image before assigning it to a VM or VMI manifest. With a DataVolume, both the pvc creation and import is automated on behalf of the user.
disks list |  | List of dictionaries which specify disks of the virtual machine. A disk can be made accessible via four different types: disk, lun, cdrom, floppy. All possible configuration options are available in https://kubevirt.io/api-reference/master/definitions.html#_v1_disk Each disk must have specified a volume that declares which volume type of the disk All possible configuration options of volume are available in https://kubevirt.io/api-reference/master/definitions.html#_v1_volume.
ephemeral boolean | Choices: no ← yes | If (true) ephemeral virtual machine will be created. When destroyed it won't be accessible again. Works only with `state` present and absent.
force boolean | Choices: no ← yes | If set to `no`, and state is `present`, an existing object will be replaced.
headless - |  | Specify if the virtual machine should have attached a minimal Video and Graphics device configuration. By default a minimal Video and Graphics device configuration will be applied to the VirtualMachineInstance. The video device is vga compatible and comes with a memory size of 16 MB.
host string |  | Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.
hostname - added in 2.9 |  | Specifies the hostname of the virtual machine. The hostname will be set either by dhcp, cloud-init if configured or virtual machine name will be used.
hugepage_size string |  | Specify huge page size.
interfaces list |  | An interface defines a virtual network interface of a virtual machine (also called a frontend). All possible configuration options interfaces are available in https://kubevirt.io/api-reference/master/definitions.html#_v1_interface Each interface must have specified a network that declares which logical or physical device it is connected to (also called as backend). All possible configuration options of network are available in https://kubevirt.io/api-reference/master/definitions.html#_v1_network.
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 are key/value pairs that are attached to virtual machines. Labels are intended to be used to specify identifying attributes of virtual machines that are meaningful and relevant to users, but do not directly imply semantics to the core system. Labels can be used to organize and to select subsets of virtual machines. Labels can be attached to virtual machines at creation time and subsequently added and modified at any time. More on labels that are used for internal implementation https://kubevirt.io/user-guide/#/misc/annotations_and_labels
machine_type string |  | QEMU machine type is the actual chipset of the virtual machine.
memory string |  | The amount of memory to be requested by virtual machine. For example 1024Mi.
memory_limit string |  | The maximum memory to be used by virtual machine. For example 1024Mi.
merge_type list | Choices: json merge strategic-merge | Whether to override the default patch merge approach with a specific type. If more than one merge type is given, the merge types will be tried in order. Defaults to `['strategic-merge', 'merge']`, which is ideal for using the same parameters on resource kinds that combine Custom Resources and built-in resources, as Custom Resource Definitions typically aren't updatable by the usual strategic merge. See https://kubernetes.io/docs/tasks/run-application/update-api-object-kubectl-patch/#use-a-json-merge-patch-to-update-a-deployment
name string / required |  | Name of the virtual machine.
namespace string / required |  | Namespace where the virtual machine exists.
node_affinity dictionary added in 2.9 |  | Describes vm affinity scheduling rules e.g. co-locate this vm in the same node, zone, etc. as some other vms
| hard dictionary |  | If the affinity requirements specified by this field are not met at scheduling time, the vm will not be scheduled onto the node. If the affinity requirements specified by this field cease to be met at some point during vm execution (e.g. due to an update), the system may or may not try to eventually evict the vm from its node.
| soft dictionary |  | The scheduler will prefer to schedule vms to nodes that satisfy the affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding `weight` to the sum if the node matches the corresponding match_expressions; the nodes with the highest sum are the most preferred.
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.
proxy - added in 2.9 |  | 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).
resource_definition dictionary |  | A partial YAML definition of the object being created/updated. Here you can define Kubernetes 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
smbios_uuid string |  | In order to provide a consistent view on the virtualized hardware for the guest OS, the SMBIOS UUID can be set.
state string | Choices: present ← absent running stopped | Set the virtual machine to either present, absent, running or stopped. present - Create or update a virtual machine. (And run it if it's ephemeral.) absent - Remove a virtual machine. running - Create or update a virtual machine and run it. stopped - Stop a virtual machine. (This deletes ephemeral VMs.)
subdomain - added in 2.9 |  | If specified, the fully qualified virtual machine hostname will be hostname.subdomain.namespace.svc.cluster_domain. If not specified, the virtual machine will not have a domain name at all. The DNS entry will resolve to the virtual machine, no matter if the virtual machine itself can pick up a hostname.
tablets list |  | Specify tablets to be used as input devices
template string |  | Name of Template to be used in creation of a virtual machine.
template_parameters dictionary |  | New values of parameters from Template.
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
wait boolean | Choices: no yes ← | True if the module should wait for the resource to get into desired state.
wait_sleep - added in 2.9 | Default: 5 | Number of seconds to sleep between checks.
wait_timeout integer | Default: 120 | The amount of time in seconds the module should wait for the resource to get into desired state.

## 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.
- In order to use this module you have to install Openshift Python SDK. To ensure it’s installed with correct version you can create the following task: pip: name=openshift>=0.8.2
