docker images --filter=reference giving seemingly unpredictable results

[pcolmer]

Description

Having read #625, I've tried using docker images --filter=reference= with various permutations of repository name, tag and wildcards … and the results seem to be a bit unpredictable. I'm not sure if it is me, the documentation or the software.

Steps to reproduce the issue:

1. Run docker images first of all to get a list of all of the images on the system.
2. Try docker images --filter reference="*:latest" as suggested by issue 625.
3. Try docker images --filter reference='linaroits*:CON*' as a wildcard filter.
4. Try docker images --filter reference='*:*18*' as a wildcard filter.
5. Try docker images --filter reference='*:*18' as a wildcard filter.
6. Try docker images --filter reference='*:CON*' as a wildcard filter.
7. Try docker images --filter reference='*:*CON*' as a wildcard filter.

Describe the results you expected:

2. I would have expected the two images with a tag of latest to be listed.

3. I would have expected the 8 images with a repository starting linaroits and a tag starting CON to be listed.

4. I would have expected linaroits/jekyllsitebuild:CON-JBC-JOB1-18 to be included in the output.

5. I would have expected linaroits/jekyllsitebuild:CON-JBC-JOB1-18 to be included in the output.

6. I would have expected all images with a tag starting CON to be listed.

7. I would have expected all images with CON somewhere in the tag to be listed which, in my case, would be the same output as test 6 would have produced.

As has been noted by @code-brewer in #625 (comment), if there is a '/' character in the repository name, it must be explicitly referenced - the '*' wildcard character does not match against it.

So docker images --filter=reference="linaroits/*:CON*" appears to work as expected and replacing the first wildcard character in my examples with */* seems to fix those as well.

Any chance it will ever be fixed? I'm writing from the near future where we are already using version 19.03.6 and it's still not working properly.

The main problem is that I need to address the images with / and without / in 2 different queries.

I still have the same issue with version 19.03.11(with SUSE Linux Enterprise Server 15 SP2 host) but not with 19.03.05(with Debian host).
