A great thing about fn is that it runs on your (Linux-)Desktop. So for a local installation, Docker needs to be installed first. On Oracle Linux this is an easy task, as everything needed is already available in the yum-repositories. Just make sure, that all needed repositories are enabled.
Docker 17.12.1 is found in the ol7_preview repository, so enable that one.
Docker depends on container-selinux, which is found in the ol7_addons repository.
Now that we have the right repositories enabled, just yum install docker-engine to get docker.
Start Docker (and systemctl enable docker, if you want to start it automatically). Then follow the Post-installation steps for Docker.
The docker group is already available, but the non-root user to run Docker needs to be added (and don't forget to logout/logon again, if you already are that user).
Check, that Docker is running correctly, if you like.
Now that Docker is running, just follow the fn installation guide to get fn.
This only takes seconds.

The whole installation is straightforward and only takes minutes (or seconds, if you already have Docker installed), then fn is ready to run. For first steps follow the official tutorial.
