How to Delete a VMware Virtual Machine Snapshot with Ansible?

I’m going to show you a live demo and some simple Ansible code. I’m Luca Berton and welcome to today’s episode of Ansible Pilot.

Ansible Delete a VMware Virtual Machine Snapshot

community.vmware.vmware_guest_snapshot
Manages virtual machines snapshots in vCenter

Let’s talk about the Ansible module vmware_guest_snapshot. The full name is community.vmware.vmware_guest_snapshot, which means that is part of the collection of modules to interact with VMware, community-supported. It manages virtual machine snapshots in vCenter.

Parameters

hostname string / username string / password string / datacenter string / validate_certs boolean - connection details
state string - present / absent / revert / remove_all
remove_children boolean - no/yes
snapshot_name string description string - Name/description of the virtual machine to work with

The following parameters are useful in order to Take a VMware Virtual Machine Snapshot using the module vmware_guest_snapshot. First of all, we need to establish the connection with VMware vSphere or VMware vCenter using a plethora of self-explicative parameters: hostname, username, password, datacenter, and validate_certs. Once the connection is successfully established you could specify the desired snapshot state, in this case, “absent” to delete a snapshot. You could also manage a snapshot with the same Ansible module. If you want to remove a snapshot you could also remove all the dependent snapshots using the parameter remove_children. You need to specify the exact snapshot name that you would like to remove in the snapshot_name parameter.
