I've moved the setting-up-docker bits into a separate page, but have left it out the TOC. I'm not sure that level of detail on docker belongs in this section; perhaps it could move to an appendix?

Configure Docker
Ensure docker is actually installed in your server instance.
=== "DNF based systems" In Rocky, Alma, and any other DNF package manager system
```console
$ sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
$ sudo dnf update -y
$ sudo dnf install -y docker-ce docker-ce-cli containerd.io
$ sudo systemctl enable docker
```
=== "APT based systems"
In Ubuntu, Debian, and other Debial APT package management systems:
```console
$ sudo apt update
$ sudo apt install -y apt-utils docker.io
$ sudo snap install docker
```
If you get an error that /etc/rc.d/rc.local is not marked executable then make it executable with sudo chmod +x /etc/rc.d/rc.local
Start Docker
$ sudo systemctl start docker
Check if Docker is running
$ systemctl status docker
Enable Non-Root User Access
After completing Step 3, you can use Docker by prepending each command with sudo. To eliminate the need for administrative access authorization, set up a non-root user access by following the steps below.
- Use the usermod command to add the user to the docker system group.
$ sudo usermod -aG docker $USER
- Confirm the user is a member of the docker group by typing:
$ id $USER
It is a good idea to restart to make sure it is all set correctly.
