Cannot run job error="Error choosing image instance: no image found in manifest list [...]

Hi @djpbessems,

ERR Cannot run job error="Error choosing image instance: no image found in manifest list for architecture amd64, variant \"\", OS linux" provider=file

These errors occur because some tags do not support the target architecture (linux/amd64):

I'll add the name of the image and the tag in the error message to make it more explicit or maybe we should ignore non-compatible tags?

Anyway you should change your rule with something like this to skip windows tags and handle semver releases of Traefik:

    - name: traefik:v2.2
      platform:
        os: linux
        arch: amd64
      watch_repo: true
      include_tags:
      - ^2\.2\.(0|[1-9]\d*)$

Or Alpine tags?

    - name: traefik:v2.2
      platform:
        os: linux
        arch: amd64
      watch_repo: true
      include_tags:
      - ^2\.2\..*-alpine

Yeah, in this case the regex for include_tags can be used to filter the images; I'll try your suggestions.

But I can imagine that's not always going to be the case, and in that case I wouldn't dare call it a user-error, so the error message is probably best just hidden (or changed to a WRN?).
