Preparing the baseline code

Now, we need to prepare our baseline code, a process very similar to what we did in the previous chapter. Let's follow these steps:

1. Copy all the content from the chapter-08 folder.
2. Rename the folder to chapter-09.
3. Delete the storage-db folder.

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

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

 version: "3.1"
 services:
     mysql:
       image: mysql:5.7
       container_name: chapter-09-mysql
       working_dir: /application
       volumes:
         - .:/application
         - ./storage-db:/var/lib/mysql
       environment:
         - MYSQL_ROOT_PASSWORD=123456
         - MYSQL_DATABASE=chapter-09
         - MYSQL_USER=chapter-09
         - MYSQL_PASSWORD=123456
       ports:
        ...
