Rebuild attached container, after base container is rebuilt?

[BrodyStone21]

Hopefully, my wording in the title isn't confusing. Let me try to explain two different container configurations that I have.

vpn -> qbittorrent

unbound -> pihole

If I update the "vpn" container, "qbittorrent" cannot work because it's attached directly to the old container. I'll have to remove "qbittorrent", and then rebuild it, attaching it to the new container. I can update "qbittorrent" without having to rebuild "vpn".

How can I make watchtower rebuild "qbittorrent" every time "vpn" is updated?

I do not use docker-compose; I use docker run. Is this possible? Right now I have "vpn" set with a label telling watchtower to only monitor it.

Yes, using a depends-on label or --link vpn, see https://containrrr.dev/watchtower/linked-containers/
