Cloning virtual machine
|
||
=======================
|
||
|
||
Workflow ``clone_vm`` defines the process of creating a new VM based on
|
||
existing VM which was created using bootable volume (and may have other
|
||
additional volumes). It's also a good example of using sub-workflows in one
|
||
workflow.
|
||
|
||
To run the example:
|
||
|
||
1. Create sub-workflows ``clone_volume.yaml`` and
|
||
``boot_vm_from_volume.yaml``::
|
||
|
||
mistral workflow-create clone_volume.yaml
|
||
mistral workflow-create boot_vm_from_volume.yaml
|
||
|
||
2. Create workflow ``clone_vm.yaml``::
|
||
|
||
mistral workflow-create clone_vm.yaml
|
||
|
||
3. Create ``input.json`` file containing workflow input parameters as follows::
|
||
|
||
{
|
||
"vm_name": "new_vm",
|
||
"flavor_ref": "1",
|
||
"source_root_vol_id": "1969299a-4c45-4900-bfe0-5ac65c1f2211",
|
||
"root_vol_name": "new_root_vol",
|
||
"root_vol_size": 1,
|
||
"additional_volumes": [
|
||
{
|
||
"vol_name": "new_user_vol_1"，
|
||
"vol_size": 1,
|
||
"source_vol_id": "94391f69-a2f7-4406-b602-86e0b421d519"
|
||
},
|
||
{
|
||
"vol_name": "new_user_vol_2"，
|
||
"vol_size": 1,
|
||
"source_vol_id": "262b37ab-86f1-4be5-ada2-645898400584"
|
||
}
|
||
]
|
||
}
|
||
|
||
5. Start workflow::
|
||
|
||
mistral execution-create clone_vm input.json
|
||
|
||
6. Get execution status by using execution id from the previous command
|
||
output::
|
||
|
||
mistral execution-get <execution_id>
|
||
|
||
7. Make sure that a virtual machine with a bootable volume and two additional
|
||
volumes has been created successfully. It can be done by opening Horizon UI
|
||
or using Nova client (python-novaclient).
