How to start this app

1. Set up your environmental variables by changing file name from .env.tmplate to .env and specify the following variables.

   APP_ENV=LOCAL
   
   MYSQL_USER=
   MYSQL_PASSWORD=
   MYSQL_ALLOW_EMPTY_PASSWORD=false
   

   • APP_ENV controls where this app is executed. Available variables are LOCAL for local environment, DEV for developing environment (dev-api-ocwcentral.onrender.com), and PROD for production environment (api-ocwcentral.onrender.com).
   • MYSQL_* are settings for a local mysql container. You can specify any value you want.

2. Start the container of this app.

   docker-compose up --build
   

3. You need to import data into the database at the first time. The mock data is available here. You can import it by running the following command.

   mysql -p　<MYSQL_PASSWORD> -h 127.0.0.1 ocw-central < /path/to/dump/file.sql
   

4. Access to localhost:8080 and you can see the app.
