Watching base image ?

[r3mi]

Hello, thanks for What's up Docker, very useful ! Question: is there a way to watch "base" image ?

Sometime, I need to customize released images, e.g.

FROM imageA:versionA
RUN some small customization

In that example, is there an easy way to watch for "imageA" ?

More complex example, when "merging" 2 images:

FROM imageB:versionB AS bb
FROM imageC:versionC
COPY --from=bb /some /stuff

In that example, is there an easy way to watch for "imageB" and "imageC" ?

Thanks !

Hi,

Right now, there is no possibility to watch base images.

wud is only watching containers, not Dockerfiles.

I'm not aware of any possible solution to get the FROM information from a container; do you?

hello, thanks, or may be , would it make sense to add a specific label to provide the image reference ? e.g.

services:
  mariadb:
    build:
      dockerfile_inline: |
        FROM mariadb:10.4.5
        RUN some customization  
      ...
    labels:
      - wud.baseimage=mariadb:10.4.5

+1 from me, a specific example from me is a vscode image where I FROM it to add additional cmd tools for other plugins. Being able to override the image name from a label would be a great addition

I came here for this same reason. I'm using Dockerfile to rebuild NGINX with the GeoIP2 module. I was hoping there would be a label. I might have to go back to using an entrypoint script until this suggestion gets implemented.
