api_port

integer

Specify the target port of the Proxmox VE cluster.

description

string

Specify the description for the snapshot. Only used on the configuration web interface.

This is saved as a comment inside the configuration file.

force

boolean

For removal from config file, even if removing disk snapshot fails.

Choices:

  • false ← (default)
  • true

hostname

string

The instance name.

retention

integer

Remove old snapshots if there are more than retention snapshots.

If retention is set to 0, all snapshots will be kept.

This is only used when state=present and when an actual snapshot is created. If no snapshot is created, all existing snapshots will be kept.

Default: 0

snapname

string

Name of the snapshot that has to be created/deleted/restored.

Default: "ansible_snap"

state

string

Indicate desired state of the instance snapshot.

Choices:

  • "present" ← (default)
  • "absent"
  • "rollback"

timeout

integer

Timeout for operations.

Default: 30

unbind

boolean

This option only applies to LXC containers.

Allows to snapshot a container even if it has configured mountpoints.

Temporarily disables all configured mountpoints, takes snapshot, and finally restores original configuration.

If running, the container will be stopped and restarted to apply config changes.

Due to restrictions in the Proxmox API this option can only be used authenticating as root@pam with api_password, API tokens do not work either.

See https://pve.proxmox.com/pve-docs/api-viewer/#/nodes/{node}/lxc/{vmid}/config (PUT tab) for more details.

Choices:

  • false ← (default)
  • true

validate_certs

boolean

If false, SSL certificates will not be validated.

This should only be used on personally controlled sites using self-signed certificates.

Uses the PROXMOX_VALIDATE_CERTS environment variable if not specified.

Choices:

  • false ← (default)
  • true

vmid

string

The instance ID.

If not set, will be fetched from PromoxAPI based on the hostname.

vmstate

boolean

Snapshot includes RAM.

Choices:

  • false ← (default)
  • true
