Docker push now defaults to latest tag instead of all tags moby/moby#40302; Added ability to change the number of reconnect attempts during connection loss while pulling an image by adding max-download-attempts to the config file moby/moby#39949; Add support for containerd v2 shim by using the now default io.containerd.runc.v2 runtime moby/moby. There are two versions of Docker – Docker CE (Community Edition) and Docker EE (Enterprise Edition). If you have a small-scale project, or you’re just learning, you will want to use Docker CE. In this tutorial, learn how to install Docker on Ubuntu 18.04.
Estimated reading time: 4 minutes Docker Enterprise Edition for Windows Server 2016 (Docker EE) enables nativeDocker containers on Windows Server 2016. The Docker EE installation packageincludes everything you need to run Docker on Windows Server 2016.This topic describes pre-install considerations, and how to download andinstall Docker EE.

Docker Universal Control Plane and Windows
With Docker EE, your Windows nodes can join swarms that are managedby Docker Universal Control Plane (UCP). When you have Docker EE installedon Windows Server 2016 and you have aUCP manager node provisioned, you can join your Windows worker nodes to a swarm.
Install Docker EE
Docker EE for Windows requires Windows Server 2016. SeeWhat to know before you install for afull list of prerequisites.
Open a PowerShell command prompt, and type the following commands.
Test your Docker EE installation by running the hello-world
container.
(optional) Make sure you have all required updates
Some advanced Docker features (like Swarm) require that Windows is updated to include the fixes in KB4015217 (or a later cumulative patch).
Select option 6) Download and Install Updates
.
Use a script to install Docker EE
Use the following steps when you want to install manually, script automatedinstalls, or install on air-gapped systems.
In a PowerShell command prompt, download the installer archive on a machinethat has a connection.
Copy the zip file to the machine where you want to install Docker. In aPowerShell command prompt, use the following commands to extract the archive,register, and start the Docker service.
Test your Docker EE installation by running the hello-world
container.
