The 'docker' user is not allowed to write to db/structure.sql - Error during dev setup

[Jothan Sargent]

Hi all,

I'm attempting to run the docker_dev_setup.sh setup script in Ubuntu 18.04.2 LTS (virtual machine running on Windows 10). It gets to a point where I see the following error:

> The 'docker' user is not allowed to write to db/structure.sql. We need write

permissions so we can run migrations.

touch: cannot touch 'db/structure.sql': No such file or directory

I don't know anything about Docker so don't know what to try next. Any ideas? Here's the output immediately preceding the error in case it is helpful:

OK to run 'chmod a+rw Gemfile.lock'? [y/n] y
