Preparing the baseline code

First, we need to prepare our baseline code, a process very similar to that of previous chapters. Follow these steps:

1. Copy all of the content from the chapter-10 folder.
2. Rename the folder chapter-11.
3. Delete the storage-db folder.

Now, let's make some changes to the docker-compose.yml file, to fit a new database and server containers.

4. Open docker-compose.yml and replace the contents with the following code:

 version: "3.1"
 services:
     mysql:
       image: mysql:5.7
       container_name: chapter-11-mysql
       working_dir: /application
       volumes:
         - .:/application
         - ./storage-db:/var/lib/mysql
       environment:
         - MYSQL_ROOT_PASSWORD=123456
         - MYSQL_DATABASE=chapter-11
         - MYSQL_USER=chapter-11
         - MYSQL_PASSWORD=123456
       ports:
         - "8083:3306"
     webserver...
