Docker is an application that simplifies the process of managing application processes in containers. In this tutorial, you'll install and use Docker Community Edition (CE) on Ubuntu 20.04. This tutorial covers how to install Docker on an Ubuntu 20.04 machine. Docker is an open-source containerization platform that allows you to quickly build, test, and deploy applications as portable containers that can run virtually anywhere.
Today we are delighted to introduce the new Minimal Ubuntu, optimized for automated use at scale, with a tiny package set and minimal security cross-section. Speed, performance and stability are primary concerns for cloud developers and ops.
“The small footprint of Minimal Ubuntu, when deployed with fast VM provisioning from GCE, helps deliver drastically improved boot times, making them a great choice for developers looking to build their applications on Google Cloud Platform,” said Paul Nash, Group Product Manager, Google Cloud.”
Smaller and faster, for automated cloud operations
Minimal Ubuntu is the smallest Ubuntu base image for your cloud operations. These images are less than 50% the size of the standard Ubuntu server image, and boot up to 40% faster. Images of Minimal Ubuntu 16.04 LTS and 18.04 LTS are available for use now in Amazon EC2, Google Compute Engine (GCE), LXD and KVM/OpenStack.
Tiny container base image
The 29MB Docker image for Minimal Ubuntu 18.04 LTS serves as a highly efficient container starting point, and allows developers to deploy multicloud containerized applications faster. For modern Docker workflows with Kubernetes, the minimal Ubuntu image provides a balance of compatibility, familiarity, performance and size. This is the standard Ubuntu 18.04 LTS image on the Docker Hub.
Cloud images also contain the optimised kernel for each cloud and supporting boot utilities.
Fully compatible with all Ubuntu packages
While the footprint of Minimal Ubuntu is greatly reduced, it preserves full compatibility with standard Ubuntu operations. Any Ubuntu package can be installed on Minimal Ubuntu. Get exactly the image you need by simply adding your required packages, with dependencies, to a Minimal Ubuntu base image.
Minimal Ubuntu is designed for completely automated operations, with none of the usual human-friendly utilities for comfortable interactive usage. Editors, documentation, locales and other user-oriented features of Ubuntu Server have been removed. What remains are only the vital components of the boot sequence. Images still contain ssh, apt and snapd so you can connect and install any package you’re missing. The unminimize tool lets you ‘rehydrate’ your image into a familiar Ubuntu server package set, suitable for command line interaction.
Optimized for cloud hypervisors
Minimal Ubuntu uses the optimized kernels on Amazon Web Services and Google Cloud. The downloadable Minimal Ubuntu image ships with a KVM-optimised kernel and tuned for boot speed and size.
Apple is moving away from the bash shell on macOS. The new macOS Catalina update will include zsh as the default shell, and older macOS versions can also move to the new shell too. Creating your own iPhone ringtones isn’t as easy as it should be, but it’s still relatively straightforward. You can do it using the new Music app in macOS Catalina, which replaces iTunes. If you’re using a Windows PC or still rocking macOS Mojave or earlier, check out our guide to adding custom iPhone ringtones using iTunes. Amazon had a surprising announcement back in December when it revealed support for Mac instances on AWS. MacOS Mojave and Catalina were the only supported operating systems at launch, and now the. Amazon has announced that the Mac instances on Amazon Web Services now support the latest version of Apple's Mac operating system, macOS Big Sur. 'Starting today, customers can run macOS Big Sur. Amazon music macos catalina. Those music tracks from Amazon Prime Music or Music Unlimited are streaming content which can only be played within itself but not compatible with any device. If you want to play Amazon Music on iPod, you may need to download and convert all songs from Amazon Music to iPod supported audio formats like MP3 or AAC and remove DRM protection from.
Minimized security cross-section
With fewer installed packages, Minimal Ubuntu images will avoid some security vulnerabilities and require fewer updates over time. Use of Minimal Ubuntu will reduce overall bandwidth consumption for an institution and require less storage.

Using Minimal Images from Dockerhub
On Dockerhub, the new Ubuntu 18.04 LTS image is now the new Minimal Ubuntu 18.04 image. Launching a Docker instance with docker run ubuntu:18.04 therefore launches a Docker instance with the latest Minimal Ubuntu.
