All the code, libraries, data, and configurations of an application, tool or service are packaged into a container. You should now be able to drop sudo from Docker commands.Docker originates from a collection of “platform-as-a-service” products and services that deliver packages known as ‘containers’ through operating system virtualization technology. 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
