# We decided to not run the installer, since the point of the installer is to setup the env, build the launch args, and setup the serivce.
# Instead, we will manually run the smaller subset of commands that are requred to get the env setup in docker.
# Note that if this ever becomes too much of a hassle, we might want to revert back to using the installer, and supporting a headless install.
