Installing Docker

We highly recommend using Linux for your NodeZero Host.

“Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and deploy it as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code.”

Linux Guide

The NodeZero Docker container can be hosted on most Linux Operating Systems by using Docker Community Edition. The following steps cover installing docker on Ubuntu. If you prefer a different Linux OS, view these other Linux references.

Install Docker on Ubuntu

sudo su

apt-get update

apt-get install docker-ce docker-ce-cli containerd.io

Ubuntu 20.04 Note

On Ubuntu version 20.04, replace the above command apt-get install docker-ce docker-ce-cli containerd.io with sudo apt-get install -y docker.io

Minimum version

Ensure you are running a version of docker greater than or equal to 20.10 (Use docker --version to find out)
