Please support docker build --secret API as in Docker 18.09

Good day,
It will be nice to be able to do

docker build --secret id=mysite.key,src=path/to/mysite.key .

through the API.

Thank you.

Can anyone please update whether there are any plans to have this implemented soon?

That feature depends on buildkit, which is very difficult to support in the Python library in its current state. We're aware of it and some work will happen to make that integration easier, but there's no ETA at the moment.

Thanks for aligning expectations :)

@haizaar I've created an issue to track BuildKit support here. I'll close this specific issue and reference it from there.
