こちらの記事を参考に
docker-compose で Rails、MySQL2 の環境構築を行い、
docker-compose upを実行したところ
ulapp_db_1 exited with code 1
とでてしまい立ち上がりません。
ログを見たところ
MYSQL_USER="root", MYSQL_PASSWORD cannot be used for the root user
とかいてあったのでパスワードがおかしいのかと思い確認しましたが
特に問題なさそうでした。
下記が関連してそうなファイルの内容です。

# MySQL. Versions 5.1.10 and up are supported.
#
# Install the MySQL driver
# gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
# gem 'mysql2'
#
# And be sure to use new-style password hashing:
# https://dev.mysql.com/doc/refman/5.7/en/password-hashing.html

encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

password: password
host: db
development:
<<: *default
database: ulapp_development
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: ulapp_test
# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
# DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
# production:
# url: <%= ENV['DATABASE_URL'] %>
#
production:
<<: *default
database: ulapp_production
username: ulapp
password: <%= ENV['ULAPP_DATABASE_PASSWORD'] %>
自分で試したこと
パスワードをpass →password に変更。
docker-compose down、
docker-compose down -v
等をしたうえでの再起動。
