Let’s Start Creating Docker Seeding

Create a new file docker-compose.yml

Above file, we have created a MySql Docker container default Port No: 3306

As well as set environment variables such as user, password of MySql container.

Docker Entry-Point

if you check the entire file we have also created volumes that point to the `./init:` directory

- ./init:/docker-entrypoint-initdb.d

The script inside `/init` is “01.sql” file which creates a new table student and inserts the records upon container startup

When you run the following command in the root directory for the project.

docker-compose up

then you will see in the console running /docker-entrypoint-initdb.d/01.sql script will be executed as the following screenshot

that means your script executed successfully.

How to test

For testing, we used Adminer configured already in the docker-compose file.
