# 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 jobs.
|
|
#
|
|
# 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.
