Setting up MariaDB Docker Deployment: 3 Easy Steps

Last Modified: February 27th, 2023

MariaDB Docker Deployment

Docker is a well-known software platform that allows developers to seamlessly create, deploy and run applications as containers. Docker offers numerous other benefits, such as its robust encapsulation, isolation, portability, and control of containers which are usually very small in size. This is why Docker is used by a wide variety of developers across the world.

This article will help you understand how you can set up MariaDB Docker deployment using the official MariaDB images for Docker.

What is MariaDB?

MariaDB is a popular Open-source Relational Database Management System (RDBMS). It was developed as a software fork of another popular Open-source database, MySQL, by the developers who played key roles in developing the original database. MariaDB was devised in 2009 when MySQL was acquired by Oracle. It was designed to ensure ease of use, speed, and reliability for all its users. 

Like all other Relational Database Management Systems (RDBMS), MariaDB houses support for ACID-Compliant Data Processing. Along with that, it also supports parallel Data Replication, JSON APIs, and multiple storage engines, including InnoDB, Spider, MyRocks, Aria, Cassandra, TokuDB, and MariaDB ColumnStore.

It is very easy to deploy MariaDB in operational agility without compromising its key enterprise features that consist of real ACID compliance and full SQL. Still, the developers are continuously working to enhance the MariaDB experience for its users. Its well-versed users are Deutsche Bank, DBS Bank, NASDAQ, Red Hat, ServiceNow, Verizon, and Walgreens industry champions who trust MariaDB for their unmatched delivery of agile operations that provides a reliable enterprise to drive collaborative innovation.

What is Docker?

Docker is a service provider tool for OS-level products to create and deploy software via containers as a complete package. These Docker containers work separately through their built-in software, libraries, and configuration files. Although they work in isolation, they can communicate with each other via a significant path. The components of Docker are as follows:

1) Docker Container

A complete package of OS services that works as a Virtual Machine to allow the application to use the same Linux kernel as that of the OS of the running machine. In this way, it reduces the size of apps that enhance the performance of the machine significantly.

2) Docker File

A DockerFile is a script used to generate a Docker Image where you can independently manage any generated change that you want to deploy via using MariaDB.

3) Docker Image

As Docker works as a Virtual Machine, so Image is a template of that virtual machine. An image in a Docker file is a complete package that could be used by the operating system, software packages, drivers, configuration files, and helper in a script bundle. Images are easy to build by any person who is well versed in writing an Image script for Docker. So, the script of an Image can vary from writer to writer but the purpose of an Image remains consistent in all varieties of Images.

Steps to Set up MariaDB Docker Deployment

Users can set up MariaDB Docker deployment by implementing the following steps:

MariaDB Docker Deployment Step 1: Installing Docker using Universal Installation Script

Running the following script will get all the necessary Docker repositories installed including packaging and Kernel modules on your Linux distributions:

curl -sSL | sh

MariaDB Docker Deployment Step 2: Starting the Docker Daemon

The Docker daemon, Dockerd can be started by running the following commands:

sudo systemctl start docker
sudo gpasswd -a "${USER}" docker

MariaDB Docker Deployment Step 3: Using MariaDB Docker Image

The best way to deploy MariaDB on Docker is to choose a MariaDB Docker image and create a container using it. This can be done by implementing the following steps:

  • Downloading the Image: MariaDB image for the Docker can be downloaded from MariaDB’s official documentation for Docker. The following command can be used to search for MariaDB Docker images:
docker search mariadb

To install the default MariaDB Docker image, the following command can be executed:

docker pull mariadb:10.x

A list of installed images can be obtained using the following command:

docker images
  • Creating a Container: An image is just the software needed to be launched. To run it, a container needed to be created first. The command to create a container for the official MariaDB Docker Image is as follows:
docker run --name mariadbprac -e MYSQL_ROOT_PASSWORD=pass -p 3308:3308 -d

The above command gives the name mariadbprac to the container. Now, the following command has to be executed:

docker run --name mariadbprac -e MYSQL_ROOT_PASSWORD=pass -p 3308:3308 -d

Docker will respond with the Container’s ID. You can get the list of Containers by the following command:

docker ps
  • Running & Stopping Container: To start the MariaDB Docker Container, the following command can be executed: 
docker restart mariadbprac

To stop the MariaDB Docker Container, the following command can be executed:

docker stop mariadbprac
  • Accessing the Container: The Container can be accessed using bash by using the following command:
docker exec -it mariadb_prac_test bash
  • Connecting MariaDB from Outside the Container: Connections to the MariaDB Server are made using TCP when the Client is running on the same machine as the Server Container. The following command is used to find the IP address of the assigned Container:
Docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' mariadprac

Now, you can connect to the MariaDB Server using a TCP connection to that IP address. The TCP Connection can be forced using the following command:

mysql -h -u root -p

Sometimes, you need to specify the port for the Server or to force TCP mode:

mysql -h -P 3308 --protocol=TCP -u root -p

This completes the deployment of MariaDB Docker and accessing the Container.


Docker is a very powerful tool for deploying applications since it creates a very robust and scalable deployment environment for both production and non-production services. It uses the concept of containerization to make processes simple and scalable. This article provided you with an in-depth understanding of how you can set up MariaDB Docker deployment using the default images.

Most businesses today use multiple platforms to carry out their day-to-day operations. As a result, all their data is spread across the databases of these platforms. If a business wishes to perform a common analysis of their data, they would first have to integrate the data from all these databases and store it in a centralized location. Building an in-house data integration solution would be a complex task that would require a high volume of resources. Businesses can instead use existing automated No-code data integration platforms like Hevo.

Hevo helps you directly transfer data from a source of your choice to a Data Warehouse, Business Intelligence, or desired destination in a fully automated and secure manner without having to write the code. It will make your life easier and make data migration hassle-free. It is User-Friendly, Reliable, and Secure.
