Nico, while you're right that latest is an anti-pattern, and you'd be forgiven for thinking that that's all Adobe offers at the ECR repo, if you looked only here.
If instead you go to the ECR repos for each of the CF versions specifically, you'll see that Adobe DOES there offer update-specific images. See the "tags" tab at the ECR pages for CF2018 and CF2021, currently listing an image tag each for the current lastest updates to those.
And the same is offered at the Docker Hub repo pages for each of CF2018 and 2021, but again some folks may stop and look only at the generic CF repo page there, which again has only the latest tag
I would agree that Adobe could/should consider either not offering that generic CF page (on both sites), or add ALL the tags in one coldfusion repo page (which is what they had done with the old BinTray/jfrog site).
That said, things are not ALL you wish them to be. First, there is only 1 specific update for each, for now (not more than one, as again the bintray site did have). I hope they will at least keep the current ones and add new ones as new updates come out. Better still would be if they would create and offer images for other past/recent updates.
Also, the "latest" tag does exist in ALL of the repo pages above, even those with an update-specific tag. To be fair, Adobe is not the only Docker image creator to follow it. In fact, it's something of a standard (for the sake of ease of use) even if it's not a best practice for fixing a specific version. Again, though, those who want to can--of course only if they think to look for it.
I did, when they posted all these. But I'm a glutton for such punishment. 🙂 Ok, I dig around so that I can help people and offer complete answers. I do appreciate that not everyone will be willing or would even think to do that, so as I said above I think Adobe could improve things.
Hope that's helpful for you and other readers.
