Docker catalog and digest using crane

I’ve written a number of bash scripts over my time to check container registry catalogs and then parse them for certain tags.

TIL that google’s crane supports this out of the box.

Install crane with arkade:

arkade get crane

Here’s the output of ls and digest:

# list all tags
crane ls danielmichaels/sitesearch
