`prune`: filtering out `ADD --checksum=... https://...` entries
Description
I'd like to be able to run docker buildx prune
but keep in cache the pinned ADD
downloads.
Could we extend on the --filter=..
syntax?
Side curiosity: why are these cache entries marked Mutable: true
?
From my understanding of du
's docs that'd mean that its size can grow.
Is there a missed optimization opportunity of in the ADD
op here, setting mutable=false
?
