How To Install and Use Docker Compose on CentOS 8 Tutorial

How To Install and Use Docker Compose on CentOS 8 (Step by Step Tutorial). In this tutorial we will introduce Docker Compose, it’s use cases with it’s main advantages then move onto installation phase. We will also explain some basic Docker Compose commands that are used to manage the Docker containers.

Docker Compose is very powerful tool that helps developers to define and share multi container applications in a single YAML file. Docker Compose is software used for defining and running multi container Docker applications. With Docker Compose, you don’t need to manually create a container for each application. You can define and run all services using a single command docker-compose up or break it up using docker-compose down.

What Is Docker Compose?

The application you use constitutes several containers running distinctive services. However, starting and managing these containers is a very difficult process. That is why Docker developed a tool called Docker Compose that speeds up this process.

This container tool is widely used by the developers and operations teams to create and automate deploying applications in lightweight containers. It ensures that these applications work in different environments appropriately.

In a nutshell, Docker Compose can handle several containers concurrently in different environments, like production, staging, development, testing, and CI.

Let’s understand the working of the tool with the help of the example.

Myntra, a fashion eCommerce brand is a very similar website to Amazon. When you visit the website via your web browser, you have to go through several activities, like logging into your account, looking at a catalog, checking the product and so on. Behind these activities contains products such as account databases, product databases, cart databases, etc.

They are known as microservices. When you build more of these microservices into your environment, the more value it provides to the services in the containers. However, being a developer, it is your responsibility to jump from one container to another. It is performed by using Docker Compose as it connects different containers as a single service.

In Docker Compose, every service runs in isolation. However, they can interact with each other whenever required.

In this blog post about how To Install and Use Docker Compose on CentOS 8 (Step by Step Tutorial) is to see the use cases for Docker Compose. 

Use Cases Of Docker Compose

Docker includes some of the common use cases that are given below:

Development Environments– docker runs an application in an isolated environment compose command line tool.

Automated Testing Environments – Docker Compose supports automated testing, an essential part of CI/CD. It is capable of creating and destroying the required testing environment. It also enables developers to define and configure the environment required for running automated end to end testing using the most appropriate file of Docker Compose.

Development Environments – With the help of Docker Compose, you can start any project quickly and efficiently. It enables the developers to immediately sign up for new isolated development environments. Its software document configures all the service dependencies of an application. This way, you can start with one or multiple containers for each dependency using a single command.

Single Host Deployment – The containers in Docker Compose are developed to run on a single host. It is because they are traditionally focused on the development and testing workflows.

Benefits Of Docker Compose

The benefits of Docker Compose are as follows:

  • Single Host DeploymentIn Docker Compose, you can run everything on a single piece of hardware.
  • Straightforward Configuration – It uses a YAML script, that makes the process of configuration quick and effortless.
  • Increased Productivity – Organizations using Docker Compose tend to experience an increase in their productivity due to a reduction in the time taken to perform every task.
  • Makes Internal Communication Secure – It enables you to share all the services in a network they have created. It also creates an extra security layer for the app since you cannot access services externally.
  • Highly Portable And Supports CI/CD – Since Docker Compose constitutes all the services in its file, you can easily access and share the configuration. When you pull a YAML file and source code, it also enables you to launch the environment within a minute. It contributes to setting up and enabling an efficient CI/CD pipeline.
  • Efficient Use Of Users – In Docker Compose, you can host multiple isolated environments in a single host. This way, you tend to save a lot of resources. It also provides features for caching a configuration and reusing existing containers, thereby contributing to resource efficiency.
  • Preserves volume data when creating containers

Next in this post is to go through steps of how to install Docker Compose on CentOS 8.

How to Install Docker Compose CentOS 8


  • A root user or a user with sudo privileges.

Install Docker Engine

Before installing Docker Compose, you will need to have Docker Engine installed on your server. If not installed, you can install it with the following command:

					dnf config-manager --add-repo=
dnf install docker-ce -y

Once the Docker Engine is installed, start the Docker service and enable it to start at system reboot with the following command:

					systemctl start docker
systemctl enable docker

Install Docker Compose

First, install the curl command line utility using the following command:

					dnf install -y curl

Next, visit the Docker Compose Git Hub release page and download the latest version of Docker Compose binary using the following command:

					curl -L "" -o /usr/local/bin/docker-compose

Once the download is completed, set the executable permission on the downloaded binary file using the following command:

					chmod +x /usr/local/bin/docker-compose

Verify Docker version

Next, verify the Docker version with the following command:

					docker-compose --version

You should see the following output:

					Docker Compose version v2.6.0

Deploy Nginx with Docker Compose

Docker Compose allows you to create a YAML file to define all your container and start them easily with a just single command. In this section, we will show you how to install Nginx with Docker Compose.

First, create a project directory to hold the Docker Compose file:

					mkdir project

Next, navgate to the project directory and create a docker-compose.yaml file with the following command:

					cd project
nano docker-compose.yml

Add the following configuration:

					version: "3"

        image: nginx
            - 8000:80


Save and close the file when you are finished. Now, run the following command to start the Nginx container:

					docker-compose up -d

This command will download the Nginx image, start the Nginx container and expose it on port 8000:

If you want to check all running container, run the following command:

					docker-compose ps

You should see your Nginx container in the following output:

					NAME                COMMAND                  SERVICE             STATUS              PORTS

Stop a container

To stop the running container, run the following command:

					docker-compose stop

You should see the following output:

					[+] Running 1/1

How To Install and Use Docker Compose on CentOS 8 Conclusion

In this post, we explained how to install Docker Compose on CentOS 8 server. We also explained how to use Docker Compose YAML file to start Nginx container. You can now use YAML file to define multiple services and start all of them with a single command.
