# ---------------------------------------------------------------------------------------------------------
# This Dockerfile is intended to be built as part of Conduit's CI pipeline.
# It does not build Conduit in Docker, but just copies the matching build artifact from the build job.
# As a consequence, this is not a multiarch capable image. It always expects and packages a x86_64 binary.
#
# It is mostly based on the normal Conduit Dockerfile, but adjusted in a few places to maximise caching.
# Credit's for the original Dockerfile: Weasy666.
