Docker on Windows

Windows 10

On Windows 10, Docker Desktop is needed. Unfortunately, it seems that a login (aka Docker ID) is needed to download the installer.

System requirements are:

Windows 10, 64-bit, Pro, Enterprise or Education, Build 15063 or later
Enabled Windows features Hyper-V and Containers
Processor has Second Level Address Translation (SLAT)
4GB Ram
BIOS has hardware virtualization support enabled

Docker Desktop includes

Docker Engine
Docker CLI client
Docker Compose
Docker Machine
Kitematic

Docker Desktop allows to use Windows Containers and/or Linux Containers.

Testing Docker after installation:

C:\> docker run hello-world

A running Docker Desktop is shown in the System Tray (sometimes its only visible when using the small arrow to the left of the symbol).

docker images shows the installed images:

c:\> docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              16464c76a19c        8 days ago          251MB

Installing Docker

Chocolatey

With Chocolatey, Docker can be installed with one of the following commands:

choco install -y docker-desktop
choco install -y docker-toolbox

In How to install Docker the Chocolatey way, Stefan Scherer points out, that docker-desktop is the preferred package for Windows 10 Enterprise while docker-toolbox is used for Windows 7 or Windows 10 Home.

Starting Desktop Container

After installing Docker with Chocolatey, Docker Desktop can be started with

C:\Users\Rene> "\Program Files\Docker\Docker\Docker Desktop.exe"

The user that tries to start Docker Desktop needs to be docker-users group, otherwise, an Access denied message is shown:

Getting started

When Docker Desktop is started the first time, it leads the user through a getting started process.

In order to complete the getting started process, Git is needed.

git clone https://github.com/docker/getting-started.git

cd getting-started

In an elevated prompt (or being assigned to the docker-users group?):

docker build -t docker101tutorial .

docker run -d -p 80:80 --name docker-tutorial docker101tutorial

Open localhost in a web browser:

Share the created image on Docker Hub (requires an account there)

docker tag  docker101tutorial %username%/docker101tutorial
docker push                   %username%/docker101tutorial

View newly created image:

C:\users\rene\getting-started> docker images

Docker users

After installing Dockers, there is a Docker Users group.
