When encountering conflict issues during Docker installation, there are generally a few ways to resolve them.

  1. Make sure the system is up to date by running sudo dnf update to update the system packages and ensure it is at the latest version.
  2. Uninstall conflicting packages: Use “sudo dnf remove ” to uninstall conflicting packages. If there are multiple conflicting packages, they need to be uninstalled one by one.
  3. Search for conflicting packages: Run sudo dnf list installed | grep to check if any installed packages conflict with Docker. Based on the search results, uninstall conflicting packages one by one.
  4. To use the official Docker repository on CentOS 8, you can install Docker without conflicting with system software packages. Simply follow these steps:
  5. Create a Docker repository file by executing sudo vi /etc/yum.repos.d/docker-ce.repo, and then copy the following content into the file:
[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://download.docker.com/linux/centos/8/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://download.docker.com/linux/centos/gpg
  1. Save and close the file.
  2. Run the installation command: Use sudo dnf install docker-ce –nobest to install Docker.
  1. Using containerization with Docker: If the above methods fail to resolve conflict issues, consider using containerization with Docker, such as using tools like Docker Compose or Kubernetes to manage and run containers.
