This multi-part blog series will show how to configure, build, and run Docker containers on Windows. The first part showed how to setup Windows Server 2016 on Virtual Box for Docker Containers. This part will install the operating system images and configure Docker. Instructions are available at msdn.microsoft.com/virtualization/windowscontainers/deployment/deployment.

Docker Container Platform for Windows articles and blog posts on the Docker website. Install Docker Desktop on Windows. Double-click Docker Desktop Installer.exe to run the installer. If you haven’t already downloaded the installer (Docker Desktop Installer.exe), you can get it from Docker Hub.

The Docker daemon pulled the 'hello-world' image from the Docker Hub. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.

Basically, to have a more manageable solution, Microsoft will stop producing docker images and instead they will publish builds as artifacts, which can be used together with the generic docker image to run the image you want. To create a Docker container with Dynamics 365 Business Central we now need to have two things.

Install Windows Server 2016 Container Feature

Start PowerShell:

Restart the Virtual Machine:

Install Windows Server 2016 Base Docker Image

Base operating system can be installed using ContainerImage PowerShell module. Install the module as:

A private Docker registry allows you to share your custom base images within your organization,keeping a consistent, private, and centralized source of truth for the building blocks of your architecture.A private Docker registry gives you better performances for big clusters and high-frequency roll-outs,plus added features like access authentication.

In an earlier post, we had a look at how one could store Docker images in Exoscale’s S3-compatible object storage.

We described how to configure a Docker registry storing images on Exoscale’s Object Storage, yet this keeps the local Docker instance responsible for the processing itself.

To improve availability, a registry would be better hosted on an external server.
Let’s see how to setup a private registry, and then later how to secure the whole thing.We will split the process in two, setting up first and securing the registry later.

What is a private Docker registry anyway?

After building a Docker image on your machine, it’s possible to run it on the spot.But if you’re a software provider, what if you want to share the image with the whole world?Or, what if you want to privately share the image with your team?

A registry can be considered private if pulling requires authentication

A Docker registry is a place where you can store your images i.e.docker push, and let third-parties get them i.e.docker pull.Docker Hub is the default registry.For example, let’s run:

In a very simplified way, the process goes like this:

Check if the hello-world image is found locally
If it isn’t, pull it from Docker Hub
Register it in the local Docker.The image is now available locally
Run it via the local Docker daemon

Note that while you can pull freely, pushing still requires some kind of authentication.
A registry can be considered private if pulling requires authentication too.

For example, GitLab, a popular Continuous Integration platform,provides a Docker registry per project among more traditional “build” capabilities,and it can be configured to be freely accessible or private.

However, GitLab’s registry is a solution that is still a bit rough around the edges.
It’s quite hard to remove images (while it’s possible to untag them though), andmore importantly, using the SaaS version of Gitlab’s registry is an all-or-nothing option:there’s no way to customize it e.g. integrate it with one’s identity store for authenticated access.

Let’s start from scratch instead, and publish our private registry on Exoscale’s cloud servers.

How to set up a private Docker registry

Good news, a Docker registry is just a Docker image!So, in order to set up a Docker registry, you first need to…setup Docker itself.

How to securely install the latest Docker release

There are two ways to install Docker:

From a package:this requires downloading a specific package and manually installing it e.g.dpkg my-package.deb
From a repository e.g.apt-get install my-package.

Installing from a repository makes updates to installed packages applied in an automated way.
The biggest advantage of this approach is that the system will always benefit from the latest security patch.In the light of some recent security scandals related to an outdated library/package, it seems there’s no other way.

Let’s choose option 2 using a fresh Ubuntu instance. To install Docker is just as easy as:

However, getting the latest and greatest version requires a bit more effort,as the official Ubuntu repository lags behind the Docker release cycle.

To do so, the official Docker package repository should first be added to the list of available repositories.This requires some preliminary setup, as it is a security-sensitive operation.

As key system components, packages should be signed and verified.The provider will sign a package using a private key, and provide a public key so that a third-party can check it’s genuine.Since the check process is handled by the system, we need to provide it with the Docker GPG public key first.
If somebody hacked the previous site to set its own key, it could impersonate the Docker organization and sign malicious packages.We need to assert this is the correct key:
0EBFCD88 is part of Docker’s public key.This should output something akin to the following:
Notice that the uid contains the string 0EBF CD88 that we searched for, as well as Docker Release (CE deb) <docker@docker.com>.At this point, we have allowed the installation of packages signed by Docker.
Add the proper repository:
Install Docker (finally):

To test the correct installation, execute this command:

This should yield the following:

Great, let’s pat ourselves on the back because at this point, Docker is (finally) ready to use.Remember that we had to process all those steps because the out-of-the-box Ubuntu repository doesn’t contain the latest version of Docker.

How to install the Docker registry on a virtual machine

Now is time for the proper Docker registry installation.Interestingly enough, this might be the easiest part of the whole setup process.As stated above, a Docker registry is just a specific running container, registry.

That command:

downloads the registry image which is tagged 2.This tag references the latest version of the registry at the time of this writing.
exposes port 5000 to the host, under the same port
gives the container the name registry instead of assigning it a random name

To make sure that the registry is running, a simple docker ps should display the following (abridged for readability):

How to push a custom Docker image to a remote private registry

Now, to test that the registry behaves as attended, let’s push a basic image to our brand-new shiny registry.We will use the hello-world image.
