Intro

Only available in Red Cloud, not available on CAC Private Clusters.


Getting Started

Installation

For a complete list of instructions, see the Docker installation guide. Docker provides instructions for both types of Linux instance types available in Red Cloud: Ubuntu and CentOS. While there are instructions for Windows, we do not recommend running Docker on Windows in Red Cloud. For this step-by-step guide, we will use a Ubuntu VM.

  1. First, launch a new instance, specifically a new Linux instance with the Ubuntu 18.04 LTS image. Access the instance via ssh.
  2. Make sure the system is up-to-date:
    • sudo apt update and sudo apt upgrade
    • You may need to run sudo reboot and reconnect once the instance has finished restarting.

Once installed, see the post installation instructions (https://docs.docker.com/engine/install/linux-postinstall/), specifically the first step on user groups. Next, their getting started page (https://docs.docker.com/get-started/) provides a good base for using Docker.
