Installation

• Install Docker and docker-compose
• Build Docker Image

git clone ssh://[email protected]:322/challengeInterface/backend.git
docker build -t backend .

• Define your container in the file docker-compose.yml:

version: '3'
services:
  db:
    image: mysql:5.7
    container_name: root_db_1
    restart: always
    ports:
      - "9999:3306"
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: hc
    volumes:
      - "/srv/mysql:/var/lib/mysql"
  backend:
    image: backend
    container_name: root_backend_1
    restart: always
    ports:
      - "8080:80"
    environment:
      MYSQL_PASSWORD: root

• Add database hc (in this example automatically)
• Change database collection from latin1_swedish_ci to utf8mb4_unicode_ci
• Execute following sql:

INSERT INTO `category` (`id`, `name`, `description`) VALUES
(1, 'hc', 'Hacking Challenges'),
(2, 'cc', 'Coding Challenges'),
(3, 'special', 'Special Challenges');
INSERT INTO `role` (`id`, `name`, `description`) VALUES
(1, 'admin', 'Admin'),
(2, 'user', 'User');

• Use docker-compose:

# Start all containers
docker-compose up -d
# Stop all containers
docker-compose stop
# Stop and remove all containers
docker-compose down  
# Start a specific container
docker-compose up -d <container>
# Stop a specific container
docker-compose stop <container>
# Stop and remove a specific container
docker-compose rm -fs <container>  
# Show logs
docker-compose logs [container]  
# Show status
docker-compose ps [container]
