Not able to use custom build base image with private registry about docker-image-resource

[baszalmstra]

Thanks, in the end I solved this by adding another task that prepends the registry to all the FROM commands using something like this:

sed -ri "s/FROM\s+/FROM $REGISTRY\//g"

Hi there!

We use Pivotal Tracker to provide visibility into what our team is working on. A story for this issue has been automatically created.

The current status is as follows:

• #121222371 Not able to use custom build base image with private registry

This comment, as well as the labels on the issue, will be automatically updated as the status in Tracker changes.

The loaded image has to match the repository referenced in FROM - in this case it doesn't (192.168.1.128:5000/baszalmstra/cross-compiler-base vs. baszalmstra/cross-compiler-base).

Gonna close this as I think the resource is technically doing the right thing, or at least something consistent with Docker's behavior.

I could see a few things to improve though: either we should warn if the image loaded as the base image will not be used as the Dockerfile, or add the ability to load the base image under a different tag so that it will end up being used. I'm a little skeptical of the latter though as it could result in confusion (Dockerfile says debian but the image loaded is actually ubuntu, etc.)

or add the ability to load the base image under a different tag so that it will end up being used

This is functionality I would like to see if there were any plans to improve things in this area.
