Question: is BuildKit supported, for SSH credentials specifically?

[ianfixes]

I'm curious about the functionality described here:
https://medium.com/@tonistiigi/build-secrets-and-ssh-forwarding-in-docker-18-09-ae8161d066

Is this buildkit functionality possible in this gem? It would simplify SSH key passing if so.

BuildKit is the default builder for users on Docker Desktop, and Docker Engine as of version 23.0. Are there any plans to implement support?

[ls-todd-lunter]

There aren't any plans to support BuildKit right now. I don't see any docs for that API on docker's website either. It is mentioned here that it is a gRPC API, but I don't see any docs for gRPC APIs on their website either.

Since that would be a fairly large departure from the existing HTTP structure for this gem, it might be worth building separately.

[mthemis-provenir]

I wonder if this can be revisited given the prevalence of BuildKit and the capability of using multi-platform builders to build for several architectures at the same time. The alternative seems to be to shell out to the docker cli to do what we want, which as you can imagine is suboptimal when the rest of the code is Ruby.
