Container Runtime Installation for NsmBox

Raspberry Pi OS, Ubuntu 20.04​

First install Docker using the docker.io package:

sudo apt install docker.io

The to run Docker as a non-root user, add that user to the docker group:

sudo usermod -aG docker pi

Then logout and back in. Using the above commands the pi user can now run Docker without sudo.

Fedora 34 (Docker)​

Docker (aka Moby) is available in the default Fedora repositories and can be installed and enabled with the following commands:

dnf install moby-engine
systemctl enable --now docker

To enable running of Docker as a non-root user, users can be added to the docker group, for example:

sudo usermod -aG docker <USERNAME>

Docker also has their own instructions for installing Docker on Fedora: https://docs.docker.com/engine/install/fedora/

CentOS 8, RHEL 8, Fedora (Podman)​

RHEL 8 and derivatives do not provide an easy way to get started with Docker, but Podman is available in the default repos. You can still use Docker, but installation instructions are not provided here.

To install Podman:

sudo dnf install podman

The main issue with Podman and an application like Suricata is that you must run the easy-suricata program as root. For example:

sudo ./easy-suricata

Or switch to root first.
