⁠How to build and use Docker for Rails project with MySQL ???

⁠1. We have to install Docker and Docker Compose on Ubuntu

• Can follow this link: https://phoenixnap.com/kb/install-docker-compose-ubuntu⁠
• Confirm that Docker and Docker Compose were installed successfully by:
  docker -v and docker-compose -v (using sudo if necessary)

⁠2. Build and run

• First, we build environment and config for our project.

docker-compose build
docker-compose run app bash (now, we'll access to virtual environment)
rails new . --database=mysql
cp config/database.yml config/database.yml.example 

• We give permission for our folder project (777).
  After that, open config/database.yml and change:

  username: root
  password: root
  host: mysql

• Change database name and open previous terminal window that in virtual environment. Run rails db:create to create database.
• Now, we run docker-compose up, open browser and access:

localhost:3000 (to access Rails project)
localhost:8080 (to access Adminer)
