Hi all,

Iâm testing a migration from 23.x to 24 and noticed a change in the Docker universe.

Background

• We use a private, read-only Docker registry served by multiple mirrors.
• Image pulls go through our custom pre-script, which handles authentication and load balancing across those mirrors.

In v24, I see a condor pull -q {imageName} step (apparently to verify the image exists). In our setup, this fails because it doesnât authenticate to the registry, and the job is then held. I havenât found a knob to disable this pre-check; ideally it would respect docker_pull_policy.

Is there a setting or another way to disable this verification stepâwithout adding a wrapper?

Hi David:

There's no knob to turn off this, but this was added in support of "docker_send_credentials = true", to have first class support for authenticated docker images.  Is there a way we can make this work for you without your custom pre-script?
