Let’s Start Creating Docker Seeding
Hope you are familiar with “Docker-Compose”
Folder structure
Project
├── docker-compose.yml (File)
├── init (Directory)
|-- 01.sql (File)

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
volumes:
- ./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.

Try to run the following URL in the browser
http://localhost:8080
and enter username, password, Server, and Database as the following screenshot.
server: db
username: user
password: user
database: mydb

Click on the login button. Then you will see there is one student table under Database: mydb as shown below

If you click on student you will see the 3 records has been created as shown below
