Docker Compose MariaDB

In this article, We will explain to you how to use Docker Compose to create MariaDB docker container

Docker Compose MariaDB Multiple Database

We will create MariaDB following multiple databases using Docker-Compose

1. mydb (use can use it for local development)
2. test (use can use it for testing)

Production Env:

The production database environment. You can use cloud databases such as AWS RDS, Heroku, etc.

Development Env:

A dedicated environment for database for local development.

Test Env:

A dedicated environment for database testing.

Why we need multiple databases?

If you have only a Production Database and you are developing a new feature if something breaks it will affect the whole Production Database.

For best practice, You must have a different Database Development Environment because if you are developing a new feature in a Development Environment if something breaks it will not impact on Production Database Environment.

Let’s Start Creating Multiple Environment Database

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

Create a new file docker-compose.yml

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

As well as set environment variables such as default username, password of MariaDB container.

if you check the entire file we have also created volumes that point to the `./init:/docker-entrypoint-initdb.d` file.

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