dtr statistics are emptry

[sagiru]

Hi,

does anybody use this script to get statistics from a docker trusted registry? If i try to do this i get only an empty output.

...docker/registry/v2> docker-registry-statistics . statistics
2020-06-02 10:53:47,663 INFO Summary counts

Hi @sagiru,

I had the same problem. You have to use the base directory of "docker/registry/v2". In your case just "cd ../../.." and try again.

Hi @thetuxkeeper ,

thx for the hint. Now it will find some repositories but the statistics arent't useful and and the end it will fail with with a KeyError:
