Version of rails: Rails 6.0.3.2. I have tried to add require 'mime' to the 20-mime_types.rb file, but it doesn't work.
You didn't mention the Redmine version you've used, but even latest Redmine for now (4.1.7) expects Rails 5.1
So please take into account official requirements
I support Rails 4.2.5 application on Ruby 2.5. Packages and rails are ok, but when I run rake assets:precompile I have error.

I don't deploy intro docker containers on ruby 2.5 image.
If you are on production environment, try RAILS_ENV=production rake assets:precompile
I think you should stick with Ruby 2.3, you could experience many runtime errors with 2.5 (like this one you reported)

# database.yml
development:
encoding: utf8
adapter: sqlite3
database: db/development.sqlite3

Then call bundle exec rake db:create && bundler exec rake db:migrate,. Hope you have bundler and sqlite3 in the Gemfile.

I think this line might be the clue
"development database is not configured"
Check the content of config/database.yml
and Gemfile to ensure you are using a database adapter that is installed. If you are using mysql for example ensure you have:
config/database.yml
development:
adapter: mysql2
encoding: utf8
database: yourDbName
username: yourSQLUser
password: passwordHere
host: 127.0.0.1
port: 3306
Gemfile
gem 'mysql2'
and mysql installed on the system also
If you were trying to run in production maybe you need to run
rake db:migrate RAILS_ENV=production
or postfix whatever command with RAILS_ENV=production
anubhav#ubuntu:~/rail$ rails generate devise MODEL , eg: rails generate devise User to generate a User model
