Doc Type: Bug Fix
Doc Text:
Cause: docker_image_availability casted openshift_docker_additional_registries to a list using the list() function. Consequence: If a string was returned (IE: only a single registry added) the result would be the string split up by component characters Fix: Force a string result from get_var to be placed inside a list. If the result is anything BUT a string the original list() function is called on the result. Result: docker_image_availability passes when it should.

Comment 3 Steve Milner 2017-09-29 16:22:01 UTC
It looks like this is the relevant error line:

Checked by: timeout 10 skopeo inspect --tls-verify=false docker://{registry}/{image}

To me, this indicates that the image test is no longer reading the registry nor image variables properly. @Luke, to your knowledge has there been any updates related to this check that would cause expansion to fail?

Comment 6 Luke Meyer 2017-10-02 14:24:17 UTC
Expansion isn't failing, that's just the generic way of telling the user what command it's using so they can replicate; it runs multiple times -- several images against all registries. If they want to see the individual invocations there's -vvv or -e openshift_checks_output_dir ...

There have been changes in this area, and I'll look into whether they're relevant, but it could also be other refactoring. I think openshift_docker_additional_registries is supposed to be an array and in true pythonic fashion, the string is being interpreted as an array of characters. Just have to find out why (specifically, why now and not before).

Comment 7 Steve Milner 2017-10-02 15:25:42 UTC
Looks like the l2_docker_additional_registries (etc..) may be the new variables to use for registries as they properly force the results into a list depending on the original import (single string or CSV string):

b35272a794 (Michael Gugino 2017-08-24 17:24:41 -0400 14) # The l2_docker_* variables convert csv strings to lists, if
b35272a794 (Michael Gugino 2017-08-24 17:24:41 -0400 15) # necessary.  These variables should be used in place of their respective
b35272a794 (Michael Gugino 2017-08-24 17:24:41 -0400 16) # openshift_docker_* counterparts to ensure the properly formatted lists are
b35272a794 (Michael Gugino 2017-08-24 17:24:41 -0400 17) # utilized.
