# build-container.mk contains utilities used by Makefiles to proxy commands to
# build containers.
#
# The following terminology is used throughout comments:
#
#   callers  Makefiles including this file
#   users    Users invoking `make`
#
# Users can supply the USE_CONTAINER=1 environment variable to inform targets
# that they should proxy build commands to the build container.
#
# Targets must opt-in to proxying support. Callers which wish to support
# proxying a Make target to the build container should be written with the
# following pattern:
#
#   <make target>:
#   ifeq $($(USE_CONTAINER),1)
#     $(RERUN_IN_CONTAINER)
#   else
#     <logic>
#   endif
#
# For example, for a `example` target to proxy an echo to a build container:
#
#   example:
#   ifeq ($(USE_CONTAINER),1)
#     $(RERUN_IN_CONTAINER)
#   else
#     echo Hello, world!
#   endif
#
# By default, no environment variables are propagated to the build container.
# Callers should set the PROPAGATE_VARS global variable to specify which
# variable names should be passed through to the container.

# Build container cache. `make build-container-cache` will create two Docker

# DOCKER_OPTS if they do.
