How to Install Docker on Centos7
If you’re looking to supercharge your development environment and streamline your deployment process, Docker is a powerful tool that can help you achieve just that. In this guide, we’ll walk you through the steps to install Docker on a CentOS 7 server.
Step 1: Update System Packages
Before we get started with installing Docker, it’s essential to ensure that your system packages are up to date. You can update the packages on your CentOS 7 server by running the following commands:
sudo yum check-update
sudo yum update
Step 2: Install Required Dependencies
Next, we need to install some necessary dependencies that Docker requires. To do this, run the following command:
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Step 3: Add Docker Repository
Now, we’ll add the official Docker repository to our system. Use the following command to add the repository:
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Step 4: Install Docker Engine
With the repository added, we can now install the Docker engine. Run the following command to install Docker:
sudo yum install docker-ce
Step 5: Start and Enable Docker
Once the installation is complete, start the Docker service and enable it to start on boot. Use the following commands:
sudo systemctl start docker
sudo systemctl enable docker
Step 6: Verify Docker Installation
To ensure that Docker has been installed correctly, you can run a simple hello-world container to verify. Execute the following command:
sudo docker run hello-world
Congratulations! You have successfully installed Docker on your CentOS 7 server. You’re now ready to take advantage of Docker’s containerization capabilities for your development and deployment needs.
