Source Code quản lý dự án bằng ruby on rails

1. Phiên bản cài đặt để chạy được dự án:
- Ruby: 3.2.2
- Rails: 7.0.7
- MySQL
- Hoặc dùng Docker cài cho nhanh

​
2. Hướng dẫn cài dự án:
2.1 Cài đặt config(chỉ chạy lần đầu)
- Tạo config database cho dự án: cp config/database.yml.example config/database.yml
- Chạy lệnh để tạo database: rails db:create
- Bật server: rails s
Truy cập đường dẫn http://localhost:3000/ hiển thị Rails là thành công

2.2 sử dụng docker

1. Install docker and docker-compose
https://docs.docker.com/engine/installation
https://docs.docker.com/compose/install
2. Setup docker on project
2.1. Copy .env file from source. Then replace the corresponding variables environment to .env file
cp .env.example .env

2.2. Change content database.yml
default: &default
adapter: mysql2
encoding: utf8mb4
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: <%= ENV["PROJECT_MANAGEMENT_DATABASE_USER"] %>
password: <%= ENV["PROJECT_MANAGEMENT_DATABASE_PASSWORD"] %>
host: <%= ENV["DATABASE_HOST"] %>
socket: /var/run/mysqld/mysqld.sock

development:
<<: *default
database: <%= ENV["PROJECT_MANAGEMENT_DATABASE_NAME"] %>
test:
<<: *default
database: project_management_test
production:
<<: *default
database: rails_tutorial_production
username: rails_tutorial
password: <%= ENV["RAILS_TUTORIAL_DATABASE_PASSWORD"] %>

2.2. Build
rails db:migrate
rails db:seed
docker-compose build

2.3. Start docker
docker-compose up -d
3. docker-compose up & docker-compose down
docker-compose up -d
docker-compose down
4. Access to docker container
4.1. List docker containers
docker ps
4.2. Exec a container
 docker exec -it bash
4.3. When change environments in docker-compose.yml file. Run the 2rd command at Step 3. or run the commands as below
# List all volumes
$ docker volume ls
# Delete a volume
 docker volume rm
4.4. To debug
docker attach project_web
