@MaikiGirardi would you like to create a patch?
You can refer to this as a reference: cecb292 (or a few options with tests like here: 2a8aaf4)

This would make me so happy. After migrating from docker to podman, I have no simple and realistic way of updating my container images through ansible. containers.podman.podman_image does have a pull option but that never updates the image even when using the latest tag.

@alive1 you can use force: true to pull image always.

@alive1 fixed in #750
