If the value is not specified in the task, the value of environment variable ACI_PRIVATE_KEY or ANSIBLE_NET_SSH_KEYFILE will be used instead.

snapshot

string / required

The name of the snapshot to rollback to, or the base snapshot to use for comparison.

The aci_snapshot module can be used to query the list of available snapshots.

state

string

Use preview for previewing the diff between two snapshots.

Use rollback for reverting the configuration to a previous snapshot.

  • "preview"

  • "rollback" ← (default)

timeout

If the value is not specified in the task, the value of environment variable ACI_TIMEOUT will be used instead.

The default value is true.

Choices:

  • false

  • true

Notes

Note

  • It is strongly recommended to add a pause task after creating a Snapshot.

  • Wait for the Snapshot to be finished before querying, comparing Snapshots or processing to Rollbacks.
