Security Note (01/21/22):

A vulnerability (CVE 2022-0185) was recently found in the Linux kernel, permitting a "User Namespace" escape (i.e., an unprivileged user inside a user-namespace may gain root access to the host). This vulnerability affects containers deployed with Sysbox as they always use the Linux user-namespace for extra isolation. To mitigate it, check if your kernel distro carries the fix. For Ubuntu, the fix has been released and requires a kernel update. Reach out to the Sysbox Slack channel for further questions.

Introduction

Sysbox Enterprise Edition (Sysbox-EE) is the enterprise version of the open-source Sysbox container runtime, developed by Nestybox.

Sysbox-EE uses Sysbox at its core, but adds enterprise-level features such as:

  • Improved container isolation / security

  • Running more types of system-level workloads inside containers

  • Scalability (running more containers per host)

  • Significant performance and efficiency optimizations (for faster container deployment with reduced disk utilization)

  • Lifecycle (higher release cadence, critical bug fixes ASAP)

  • Nestybox professional support with a guaranteed SLA (rather than best effort on Sysbox)

  • Feature prioritization (Sysbox-EE feature requests are prioritized)

For these reasons, **we recommend that enterprises that wish to use Sysbox in their IT infrastructure use Sysbox-EE**.

Sysbox-EE is a drop-in replacement for Sysbox. It installs and it's used in the exact same way, but includes the enterprise level features described above. On a given host however, either Sysbox or Sysbox-EE must be installed, never both.

See the next sectionfor a comparison between Sysbox-EE and Sysbox (aka Sysbox Community Edition or Sysbox-CE).

Features & Pricing

Sysbox-EE is offered via a 30-day free trial and a paid subscription after that.

Features and pricing info are shown below.

sysbox

(*) For pricing purposes, a "host" is a computer (bare-metal or virtual-machine) with up to 16 CPU cores (32 hyper threads). Per-core pricing at $5 per-core per-month is also available for hosts with < 8 cores. Licensing is per-year. Volume discounts available for 50+ per-host licenses or 350+ per-core licenses.

You can download Sysbox-EE for free and use it during the free trial period. Afterwards, we ask that you contact Nestybox for pricing and payment information.

If you have questions, you can reach us here.

Supported Distros

Sysbox-EE relies on functionality available only in relatively recent Linux kernel releases.

See the distro compatibility doc for information about the supported Linux distributions and the required kernel releases.

We plan to add support for more distros in the near future.

Host Requirements

The Sysbox-EE host must meet the following requirements:

  • It must be running one of the supported Linux distros.

  • We recommend a minimum of 4 CPUs (e.g., 2 cores with 2 hyperthreads) and 4GB of RAM. Though this is not a hard requirement, smaller configurations may slow down Sysbox-EE.

Installation

Sysbox-EE is a drop-in replacement for Sysbox, meaning that it's installed and used in the same way.

For this reason, the documents in the Sysbox repo apply equally to both Sysbox and Sysbox-EE.

Here are the links to the docs showing how to install Sysbox-EE:

Using Sysbox-EE

Once Sysbox-EE is installed, you create a container using your container manager or orchestrator (e.g., Docker or Kubernetes) and an image of your choice.

Docker command example:

$ docker run --runtime=sysbox-runc --rm -it --hostname my_cont registry.nestybox.com/nestybox/ubuntu-bionic-systemd-docker
root@my_cont:/#

Kubernetes pod spec example:

apiVersion: v1
kind: Pod
metadata:
  name: ubu-bio-systemd-docker
  annotations:
    io.kubernetes.cri-o.userns-mode: "auto:size=65536"
spec:
  runtimeClassName: sysbox-runc
  containers:
  - name: ubu-bio-systemd-docker
    image: registry.nestybox.com/nestybox/ubuntu-bionic-systemd-docker
    command: ["/sbin/init"]
  restartPolicy: Never

You can choose whatever container image you want, Sysbox-EE places no requirements on the image.

Refer to the Documentation section below for further examples on how to use Sysbox-EE.

Documentation

The following documents in the Sysbox repo show how to use Docker and Kubernetes to deploy containers with Sysbox.

These docs apply equally to both Sysbox and Sysbox-EE.

Features that are specific to Sysbox-EE are tagged with "Sysbox-EE Feature Highlight" in the docs.

  • Sysbox Quick Start Guide

    • Provides many examples for using Sysbox to deploy enhanced containers. New users should start here.
  • Sysbox User Guide

    • Provides more detailed information on Sysbox features and troubleshooting.

In addition, the Nestybox blog site has articles on how to use Sysbox to deploy containers.
