Role does not exist, maybe you have not run DB migrations

[arunk]

I just ran a fresh bbb-3.0 alpha.7 install using the bbb-install script and installed Greenlight with it. I'm trying to setup an admin user for greenlight. So I tried to run: $ docker exec <greenlight:v3-container-id> exec bundle rake user:create["name","email","password", "user"]. I got this error: Unable to create user: 'arun' Role 'user' does not exist, maybe you have not run the DB migrations?

So I ran db:migrate and it ran without reporting any errors. But that didn't fix the issue.

Then I found this issue #1743 and I tried what it said:

docker exec -it greenlight-v2 bash
bundle exec rails c
Role.all.pluck(:name, :provider)

And I got back this output:
=> [["Administrator", "greenlight"], ["User", "greenlight"], ["Guest", "greenlight"], ["SuperAdmin", "bn"]]

Ok I finally figured out the issue, but I'm leaving it here in case anyone else faces the same problem, because documents linked in these issues like the one to gl-admin on bbb docs no longer exist.

So I had to use the bundle exec rake user:create and use the role 'Administrator' instead of 'admin' and also I tried 'SuperAdmin' and that didn't work either.

Also I tried #1753 and what it said about Role.create_default_roles("greenlight") and that gave an error about create_default_roles method not existing. So I guess this has changed in greenlight v3.
