Docker uses virtualization technology to provide isolated containers for software and tools. This article will show you the easiest way to install Docker on Ubuntu 20.04 and get it running in less than 5 minutes. Before: I had docker-compose version: docker-compose version 1.21.2, build a133471 So to upgrade to latest non-RC version, I found this to work in order to upgrade: 1) apt install python-pip to install PIP then pip install docker-compose to install the latest and then to check the version: docker-compose -version which gave me: docker-compose.

This page contains information about hosting your own registry using theopen source Docker Registry. For information about Docker Hub, which offers ahosted registry with additional features such as teams, organizations, webhooks, automated builds, etc, see Docker Hub.

What it is

The Registry is a stateless, highly scalable server side application that storesand lets you distribute Docker images. The Registry is open-source, under thepermissive Apache license.

Why use it

You should use the Registry if you want to:

tightly control where your images are being stored
fully own your images distribution pipeline
integrate image storage and distribution tightly into your in-house development workflow

Alternatives

Users looking for a zero maintenance, ready-to-go solution are encouraged tohead-over to the Docker Hub, which provides afree-to-use, hosted Registry, plus additional features (organization accounts,automated builds, and more).
