buildkit support?
We're running a docker build using the buildkit in order to cache pip packages between builds using the --mount
option.
However, it seems that this fails: https://gitlab.cern.ch/LHCb-RD/ewp-rk-rkst-highq2/-/jobs/18068711
I've been using the BUILD_ARG: DOCKER_BUILDKIT=1
argument in order to activate the buildkit and also added the experimental flag at the beginning of the Dockerfile (# syntax=docker/dockerfile:experimental
)
Do you have an idea why this fails?
