How to get base docker image tag version?

Viewed 531

I have a docker (with dockerfile) which was built from base docker with not tag (meaning it's the latest tag).

The docker was built a year ago, and I want to know which tag (version) we used.

(FROM baseDocker, what is the version/tag of baseDocker)

Is there a way I can get the tag of the base docker, the dockerfile used ?

I have tried to view the information from docker image inspect but I'm not sure what and where to search there
