Docker installation is available in the official CentOS 7 repository which is not the latest version. Installing the Docker on CentOS 7īefore we begin the installation we need CentOS 7 64 bit and need a user who is non root with sudo permissions. Here for demo purpose, we will install on the existing OS. First method is to by installation using the existing OS or spinning the server with a tool called Docker Machine and making the auto installation. There are two methods of installing Docker on CentOS 7. It works like a virtual machine which are more portable and more resource friendly and more dependent on the host OS. Dockers is a very good tool which runs the application on its own containers. You should now be able to drop sudo from Docker commands.In this article, we will learn how to install Dockers. Alternatively, run the newgrp docker command to immediately login to the updated group.

Once you’re in the group, logout and login again. Adding yourself to the docker group will let you use Docker without sudo.

This can get tedious if you’re using Docker often. You must usually prefix Docker commands with sudo. Install Docker: sudo yum install docker-ce docker-ce-cli containerd.io Using Docker Without Sudo Install Docker: sudo dnf install docker-ce docker-ce-cli containerd.io CentOSĪdd Docker’s package repository: sudo yum -y install yum-utils Now you can install Docker: sudo apt-get install docker-ce docker-ce-cli containerd.io FedoraĪdd Docker’s package repository: sudo dnf -y install dnf-plugins-core

Next, add Docker’s repository GPG key: curl -fsSL | sudo gpg -dearmor -o /usr/share/keyrings/docker-archive-keyring.gpgĪdd the repository to your sources and update your package lists: echo 'deb $(lsb_release -cs) stable' | sudo tee /etc/apt//docker.list > /dev/null Sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release Begin by adding dependencies needed by the installation process: sudo apt-get update
