Dockerfile

# This is a Dockerfile to _build_ launcher. It's expected that most
# usage will us multi-stage builds, with this as stage1. See the
# docker/ directory and associated Make targets.
#
# Note that multistage builds can leverage the tag applied (at build
# time) to this container

# The launcher build is generally not GOPATH, however, we do assume

# We need the launcher source to build launcher. We can get this one
# of three ways. git clone, copy, or mount. git clone was chosen, as
# it's the least bad.
# COPY is slow, and can pull in cruft from the working dir
# mount can pull in cruft from the working dir, and can pollute the working dir
# git clone ensures clean source
