Watch digest not working

[NChief]

I have container running postgresql:

---
services:
  db:
    image: 'postgres:15'
    labels:
      - wud.tag.include=^\d+$$
      - wud.watch.digest=true

But wud keeps saying that there is an update to 17 available. I do not want 17. But I do want to know if the digest on the 15 tag has changed.

Am I misunderstanding something? This is taken more or less straight from the documentation.

You currently watch for tags consisting of any number (regex \d+). You want to watch for changes only for tag 15. change wud.tag.include=^\d+$$ to wud.tag.include=^15$$.
