### `AllTags=`
@ -1150,6 +1151,19 @@ performance and robustness reasons.
The format of the name is the same as when passed to `podman pull`. So, it supports using
`:tag` or digests to guarantee the specific image version.
### `ImageTag=`
Actual FQIN of the referenced `Image`.
Only meaningful when source is a file or directory archive.
For example, an image saved into a `docker-archive` with the following Podman command:
`podman image save --format docker-archive --output /tmp/archive-file.tar quay.io/podman/stable:latest`
requires setting
- `Image=docker-archive:/tmp/archive-file.tar`
- `ImageTag=quay.io/podman/stable:latest`
### `OS=`
Override the OS, defaults to hosts, of the image to be pulled.
