- `author_id` (string) - who created the iteration - `bucket_name` (string) - Name of the bucket that the iteration was retrieved from - `complete` (bool) - If true, this iteration is considered "ready to use" and will be returned even if the include_incomplete flag is "false" in the list iterations request. Note that if you are retrieving an iteration using a channel, this will always be "true"; channels cannot be assigned to incomplete iterations. - `created_at` (string) - The date the iteration was created. - `fingerprint` (string) - The fingerprint of the build; this could be a git sha or other unique identifier as set by the Packer build that created this iteration. - `id` (string) - The iteration ID. This is a ULID, which is a unique identifier similar to a UUID. It is created by the HCP Packer Registry when an iteration is first created, and is unique to this iteration. - `incremental_version` (int32) - The version number assigned to an iteration. This number is an integer, and is created by the HCP Packer Registry once an iteration is marked "complete". If a new iteration is marked "complete", the version that HCP Packer assigns to it will always be the highest previous iteration version plus one. - `updated_at` (string) - The date when this iteration was last updated. - `channel_id` (string) - The ID of the channel used to query the image iteration.
