dendrite/build/scripts/ComplementLocal.Dockerfile

# A local development Complement dockerfile, to be used with host mounts
# /cache -> Contains the entire dendrite code at Dockerfile build time. Builds binaries but only keeps the generate-* ones. Pre-compilation saves time.
# /dendrite -> Host-mounted sources
# /runtime -> Binaries and config go here and are run at runtime
# At runtime, dendrite is built from /dendrite and run in /runtime.
#
# Use these mounts to make use of this dockerfile:
# COMPLEMENT_HOST_MOUNTS='/your/local/dendrite:/dendrite:ro;/your/go/path:/go:ro'
