2. To let the system recognize the added Docker repository and the packages available in the same, run the system update that will force AlmaLinux to rebuild the system repo cache.
$ sudo dnf update
3. You can check the added repo including others of your system using the command.
$ sudo dnf repolist -v
4. Run the Command to Install Docker CE Engine.
$ sudo dnf install docker-ce docker-ce-cli containerd.io
5. Once the installation is completed, start the Docker service on your AlmaLinux and also enable it to run automatically with system boot.
$ sudo systemctl enable docker
$ sudo systemctl start docker
6. Check the Status of the Service to know it is working properly.
$ systemctl status docker
