Step-by-Step Guide:

  1. Prerequisites:
    • Ensure you have a CentOS server with root access.
    • Install Docker on your CentOS server. If Docker is not already installed, follow these steps:
      • Update your system: sudo yum update
      • Install required packages: sudo yum install -y yum-utils device-mapper-persistent-data lvm2
      • Set up Docker repository: sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
      • Install Docker: sudo yum install -y docker-ce
      • Start and enable Docker service: sudo systemctl start docker && sudo systemctl enable docker
      • Verify Docker installation: docker --version
  2. Installing Docker Compose:
    • Download the Docker Compose binary: sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    • Set the correct permissions: sudo chmod +x /usr/local/bin/docker-compose
    • Verify the installation: docker-compose --version
  3. Understanding Docker Compose YAML:
    • Familiarize yourself with the structure and syntax of Docker Compose YAML files.
    • Understand how to define services, networks, and volumes within the YAML file.
  4. Creating a Docker Compose File:
    • Create a new file for your Docker Compose configuration, such as docker-compose.yml.
    • Define your services, networks, and volumes within the YAML file.
    • Specify container images, ports, environment variables, and any other necessary configurations for your application.
  5. Running Docker Compose:
    • Navigate to the directory where your Docker Compose file is located: cd /path/to/docker-compose-file
    • Start your application containers: docker-compose up -d
    • View logs for running services: docker-compose logs
    • Stop your application containers: docker-compose down
  6. Managing Docker Compose Services:
    • Check the status of running services: docker-compose ps
    • Execute commands inside a running container: docker-compose exec <service-name> <command>
    • Inspect logs for a specific service: docker-compose logs <service-name>
    • Remove stopped containers: docker-compose rm
  7. Scaling and Updating Services:
    • Scale services up or down: docker-compose up -d --scale <service-name>=<desired-instances>
    • Update your application by modifying the Docker Compose file: docker-compose up -d
  8. Additional Resources and References:
    • Official Docker Compose documentation: link
    • Docker Community: link
    • CentOS: link


By following this comprehensive guide, you have successfully installed Docker Compose on your CentOS server and learned how to leverage its capabilities for managing multi-container applications. Docker Compose’s YAML-based configuration and easy-to-use commands simplify the deployment, scaling, and updating processes, making it an invaluable tool for containerized application management. Refer to the provided resources and references for further exploration and support as you continue your Docker Compose journey.
