To install docker in CentOS without getting a migraine, try this command and see the magic unfold on your terminal screen: sudo dnf install docker-ce -nobest Basically, it helps you automatically install the most suitable package version with all the dependencies satisfied. It will check the latest version of docker-ce but when it finds the dependency issue, it checks the next available version of docker-ce.
To avoid this dependency cycle and battling them manually, you can use the -nobest option of the dnf command. Now, this version of containerd.io is not available in CentOS 8. But the problem in installing the latest version is that it depends on containerd.io version >=1.2.2-3. I got docker-ce-3:19.03.9-3.el7 as the latest version. The trouble with using a custom repository is that it may have dependency issue if you try installing the latest version of docker-ce.įor example, when I check the available versions of docker-ce with this command: dnf list docker-ce -showduplicates | sort -r You should also update the package cache after adding a new repository: sudo dnf update You can update the CentOS using: sudo dnf updateĪdd docker's official repository using the following command sudo dnf config-manager -add-repo Installing Docker on CentOSīefore going any further, make sure you have the system updated. Most of the world uses Docker CE and it is often considered synonymous to Docker. There is Docker EE (Enterprise Edition) with paid support. This is the free and open source version of Docker. Docker CE stands for Docker Community Edition. Here, I'll walk you through the installation process of Docker CE using docker's RPM repository. However, Docker is not available in CentOS's default repositories.įret not, there are three ways you can install docker on a CentOS Linux system. I have uninstalled docker-ce-20.10.6, clean up /var/lib/docker folder and reinstall with command "yum install docker-ce-20.10.5.īut this isn't installing docker-ce-20.10.5, rather pointing to 20.10.6.Īny idea how can I make 20.10.5 version as default, and remove 20.10.Installing Docker on Ubuntu is simple because Ubuntu provides Docker in its repositories. However, I want to use docker-ce.20.10.5. Previously I had installed docker-ce-20.10.6.
