I have been experimenting container images compressed in zstd format lately.
It looks like Docker Hub is capable of storing zstd compressed images but lacks support in Vulnerability Scanning against zstd images.
Per my evaluation, gzip compressed images were scanned almost instantly after pushing, but zstd compressed images were never shown as “scanned”.
So I’d like to know:
- Is zstd supported by Vulnerability Scanning feature?
- If not, is supporting zstd images on the roadmap?
