Unleash the Power of Containers: Effortlessly Install Docker CE and Docker Compose on CentOS/Red Hat
In the ever-evolving landscape of software development and deployment, Docker has emerged as a revolutionary tool, enabling developers to encapsulate their applications in containers. This encapsulation facilitates seamless development, testing, and deployment across diverse environments. If you’re navigating the CentOS or Red Hat ecosystem, integrating Docker into your workflow can significantly enhance your productivity and operational efficiency. This guide will walk you through the steps to install Docker Community Edition (CE) and Docker Compose on CentOS/Red Hat, and how to kickstart the Docker service, transforming your system into a powerhouse for container management.
Step 1: Prepare Your System
Before diving into the installation process, ensure your system is ready. Begin by updating your package database to make sure you have access to the latest versions of software:
sudo yum update- Install required dependencies:
sudo yum install -y yum-utils device-mapper-persistent-data lvm2- Step 2: Install Docker CE
Docker CE is the community edition of Docker, offering a robust set of features free of charge. To install Docker CE on CentOS or Red Hat, follow these steps:
- Add the Docker Repository:
First, add the Docker repository to your system to access the Docker packages.
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo- Install Docker CE:
With the repository added, you can now install Docker CE along with its command-line interface (CLI) and the containerd.io package.
sudo yum install docker-ce docker-ce-cli containerd.ioStep 3: Install Docker Compose
Docker Compose is a tool that allows you to define and run multi-container Docker applications. To install Docker Compose, execute the following command:
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-composeThen, apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-composeStep 4: Start the Docker Service
With Docker CE and Docker Compose installed, the next step is to start the Docker service:
sudo systemctl start dockerTo ensure Docker starts automatically at boot:
sudo systemctl enable dockerStep 5: Verify Your Installation
Confirm that Docker CE and Docker Compose are correctly installed by checking their versions:
docker --version
docker-compose --versionUnleashing the Potential
Congratulations! You’ve successfully installed Docker CE and Docker Compose on your CentOS/Red Hat system.
