Unable to install Docker on RHEL 8.9 from package (2nd Method)

Hello everyone I’m installing docker on a RHEL machine (version: 8.9 - arch: x86_64). However I use the second method that is to say by downloading all packages .rpm . However once installed there is no docker service created. Should I configure/ create my own docker daemon service? Do I need other prerequisites? Can you explain what’s missing?

Maybe link to the page you used?

As the docker installation is not yet supported by RHEL I left with what advise CentOS: Install Docker Engine on CentOS | Docker Docs
