Hanging during Docker webpack build

I’m attempting to setup Superset on an AWS t3.micro instance. When running:

cd incubator-superset/contrib/docker && \
  docker-compose run --rm superset ./docker-init.sh

The command hangs during the webpack build phase.

Expected results

The build will complete.

Actual results

The command hangs with the following output:

# ...

Hi, to whomsoever it may help, I was able to get it working after increasing the total runtime memory available to docker from 2GB to 4GB.
