Docker setup doesn't work: `docker-compose run --rm web ./script/install_assets.sh` fails

[ldorigo]

The docs say:

Now we can install assets, create and migrate databases.

docker-compose run --rm web ./script/install_assets.sh docker-compose run --rm web bundle exec rake db:create db:initial_setup docker-compose run --rm web bundle exec rake db:migrate RAILS_ENV=test

However, docker-compose run --rm web ./script/install_assets.sh fails because ./script/install_assets.sh does not exist inside the container, and the docs don't mention any step in which that file should be copied inside the container?

(for reference, the error I get is:

I ran into this exact issue - it was caused by the bind mount in the docker-compose.override.yml not passing through everything (including and especially the script folder); this was ultimately caused by me running Docker-in-Docker, though there are likely other causes.
