# Build gitd. The version comes from the GIT_VERSION arg, written to the VERSION
# file the Makefile prefers over `git describe`. The native runner fabric exports
# a tree rather than a clone, and the earlier bind on .git failed there with
# "/.git: not found"; line 39 excludes .git from the COPY as well, so inside this
# image the arg is the ONLY source of a version — a build that omits it gets
# 0.0.0+unknown whether or not it started from a clone. hanzoai/cloud passes it
# from the image tag (clients/platform buildFrontendCmd), which is why a tagged
# build is versioned and an ad-hoc `docker build` is not.
