Manages OpenNebula instances

Requirements ¶

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

python-oca

Parameters ¶

Parameter	Choices/Defaults	Comments
api_password -		Password of the user to login into OpenNebula RPC server. If not set
api_url -		URL of the OpenNebula RPC server. It is recommended to use HTTPS so that the username/password are not transferred over the network unencrypted. If not set then the value of the `ONE_URL` environment variable is used.
api_username -		Name of the user to login into the OpenNebula RPC server. If not set then the value of the `ONE_USERNAME` environment variable is used.
attributes -	Default: {}	A dictionary of key/value attributes to add to new instances, or for setting `state` of instances with these attributes. Keys are case insensitive and OpenNebula automatically converts them to upper case. Be aware `NAME` is a special attribute which sets the name of the VM when it's deployed. `#` character(s) can be appended to the `NAME` and the module will automatically add indexes to the names of VMs. For example':' `NAME':' foo-###` would create VMs with names `foo-000`, `foo-001`,... When used with `count_attributes` and `exact_count` the module will match the base name without the index part.
count -	Default: 1	Number of instances to launch
count_attributes -		A dictionary of key/value attributes that can only be used with `exact_count` to determine how many nodes based on a specific attributes criteria should be deployed. This can be expressed in multiple ways and is shown in the EXAMPLES section.
count_labels -		A list of labels that can only be used with `exact_count` to determine how many nodes based on a specific labels criteria should be deployed. This can be expressed in multiple ways and is shown in the EXAMPLES section.
cpu -		Percentage of CPU divided by 100 required for the new instance. Half a processor is written 0.5.
disk_saveas -		Creates an image from a VM disk. It is a dictionary where you have to specife `name` of the new image. Optionally you can specife `disk_id` of the disk you want to save. By default `disk_id` is 0. NOTE':' This operation will only be performed on the first VM (if more than one VM ID is passed) and the VM has to be in the `poweredoff` state. Also this operation will fail if an image with specified `name` already exists.
disk_size -		The size of the disk created for new instances (in MB, GB, TB,...). NOTE':' This option can be used only if the VM template specified with `template_id`/`template_name` has exactly one disk.
exact_count -		Indicates how many instances that match `count_attributes` and `count_labels` parameters should be deployed. Instances are either created or terminated based on this value. NOTE':' Instances with the least IDs will be terminated first.
group_id -		ID of the group which will be set as the group of the instance
hard boolean	Choices: no ← yes	Reboot, power-off or terminate instances `hard`
instance_ids -		A list of instance ids used for states':' `absent`, `running`, `rebooted`, `poweredoff` aliases: ids
labels -	Default: []	A list of labels to associate with new instances, or for setting `state` of instances with these labels.
memory -		The size of the memory for new instances (in MB, GB, ...)
mode -		Set permission mode of the instance in octet format, e.g. `600` to give owner `use` and `manage` and nothing to group and others.
networks -	Default: []	A list of dictionaries with network parameters. See examples for more details.
owner_id -		ID of the user which will be set as the owner of the instance
state -	Choices: present ← absent running rebooted poweredoff	`present` - create instances from a template specified with `template_id`/`template_name`. `running` - run instances `poweredoff` - power-off instances `rebooted` - reboot instances `absent` - terminate instances
template_id -		ID of a VM template to use to create a new instance
template_name -		Name of VM template to use to create a new instace
vcpu -		Number of CPUs (cores) new VM will have.
wait boolean	Choices: no yes ←	Wait for the instance to reach its desired state before returning. Keep in mind if you are waiting for instance to be in running state it doesn't mean that you will be able to SSH on that machine only that boot process have started on that instance, see 'wait_for' example for details.
wait_timeout -	Default: 300	How long before wait gives up, in seconds
