Using the Docker-compose you can include the Docker containers into a docker-compose.yml file and mention all container services or configurations that are necessary for an application. This tool can be used in the development, testing, and production environment, apart from all of these facts it also helps in Continuous Integration workflow.

Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform related Docker Compose queries.

In this context, we shall look into the process of installing the Docker-compose on CentOS 8 system.

Also, you will learn how you can use and configure it on your system through the command-line.

How to use Docker-compose on CentOS 8?

All configurations about the containers-based services and container images are defined in the 'docker-compose.yml' file. 

i. Here, we are pulling container images of WordPress and MySQL by using the following commands:

$ sudo docker pull wordpress
$ sudo docker pull mysql
$ sudo docker image ls

ii. Now, create a new directory with the name 'wordpress-site' and navigate into it as follows:

$ mkdir wordpress-site
$ cd wordpress-site/

iii. Here, create a docker-compose file ‘docker-compose.yml’ and paste the following code in this file:

version: '3.0'
    image: wordpress
    container_name: wp_web
      - 8080:80
      - dbserver:mysql
    image: mysql:latest
    container_name: wp_db

In the above file, two different container services are defined such as 'webserver' and 'dbserver'. We have also defined container images and then mentioned the WordPress and dbserver passwords.

iv. Now, deploy these containers by running the below-mentioned command as the root user:

# docker-compose up

v. Now, browser the WordPress site URL:


vi. To start and stop the containers, use the following commands respectively:

# docker-compose start
# docker-compose stop

vii. To explore more about the Docker-compose usage, use the following command:

$ docker-compose --help
