Creating snapshot of an Openstack server/instance using Ansible

[Abdul Wahab]

Hello Everyone,

I have been trying to find an ansible-module that can create a snapshot of a running server/instance on Openstack cloud. I have looked into os_image, os_server_action and os_server modules but couldn't find the option. From the command line you can easily get this snapshot using the command 

openstack server create --name <snapshot-name> <instance-name>

I am running this playbook on the controller node of openstack.

Any suggestion on how can I obtain the equivalent results of the above command using Ansible?

Hello,

I'm also new to ansible and I had the same problem with you. I got hint from this answer. My solution is just using the command as you stated in question, additionally with auth information:

- name: create snapshot for instance

  become: false

  delegate_to: 127.0.0.1

  ansible.builtin.command: openstack server image create --name {{snapshot_name}} {{headNode_name}} --os-auth-url="{{my_auth_url}}" --os-application-credential-id="{{my_application_credential_id}}" --os-application-credential-secret="{{my_application_credential_secret}}" --os-auth-type="{{my_auth_type}}"

The prerequisite is to have openstackcli installed locally.

Hope that helps!
