   # GVM_NO_UPDATE_PROFILE=true means do not alter /root/.bashrc to automatically source gvm config, so when not using runner.sh, image works normally
   # Install the tool:
  -RUN curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer | GVM_NO_UPDATE_PROFILE=true bash

   # gvm requires one to "source /root/.gvm/scripts/gvm" after installing
   #  but in Dockerfile, each RUN is its own shell, so source'd in-RUN env vars are not propagated
   # So have created "source-gvm-and-run.sh" to source the above then run gvm
