Caveat when connecting your BC container to a default SQL instance or why does importing the encryption key fail
Considering the big news today, this is only a small nugget of information but as I wasted a couple of hours trying to find out what goes wrong, I still wanted to share it: Connecting a BC or NAV container against a SQL Server running outside of that container is pretty easy, you just need…

A german introduction to Windows Containers
I had the honor to speak about Windows Containers at the Cloud & Datacenter Conference Germany. Not a large conference, but very well organized with a clear focus and as far as I had the chance to talk to participants, a very satisfied audience. For the first time this year they recorded the sessions, so…

Improvements to the Traefik usage with NAV/BC or why Open Source is awesome
I had introduced the usage of Traefik with NAV/BC containers and also shared the integration into navcontainerhelper over the last couple of months. As always, there was room for improvement and to my delight Damien Duportal, Developer Advocate at Containous, the company behind Traefik, contacted me via email to suggest three important changes: I had…

Traefik support for navcontainerhelper, the NAV ARM templates for Azure VMs and local environments
I had recently written about the usage of traefik as reverse proxy for multiple Business Central containers on an Azure VM. While I tried to make that setup quite easy, as always there was room for improvement. With the help of Freddy Kristiansen I therefore implemented two additions to navcontainerhelper and the NAV ARM templates…

Running Docker containers in process isolation when Symantec Endpoint Protection is installed
A couple of month ago, Microsoft and Docker enabled process isolation for Docker containers on Windows 10. That matters a lot because the alternative is hyper-v isolation which means that you actually run a "mini VM" every time you run a container. Depending on the circumstances, that can be a very desirable feature but when…

Using the Container extension for Windows Admin Center
Windows Admin Center (formerly known as "Project Honolulu") is the new browser-based administration tool for Windows Server, intended to replace the old Server Manager and actually already quite good at it. If you want to find out more, see https://docs.microsoft.com/en-us/windows-server/manage/windows-admin-center/overview where it is quite well documented. Not so well documented at least to my knowledge…

Get DNS name resolution for your NATed Windows Docker containers
The standard setup for Windows Docker containers is to connect new containers to a NAT network. For more information see Microsoft Docs, but basically it means that a new container gets an IP address from an internal network which is only reachable form the host (your laptop or VM where the container is running). That…

Running multiple NAV/BC containers on an Azure VM
When you want to get started with using NAV/BC containers and have an Azure subscription, then the very easy route is to just use one of Microsoft's quickstart ARM templates like http://aka.ms/getbc. This will create a VM on Azure with Docker, one pre-defined container, navcontainerhelper, VS Code and all the bells and whistles you might…

Running multiple NST / BCST instances connected to the same database with Docker compose
I recently encountered a somewhat unexpected behavior of the NAV / Business Central Service Tier when running multiple instances connected to the same database. It sometimes happens that our heavily code customized solution behaves differently than a standard Cronus database, so I decided to try to repro in a standard out-of-the-box environment. Of course I…

Allow access to the Docker Engine without admin rights on Windows
If you have been working with Docker on Windows, the following message is probably familiar: error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/containers/json: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is…

DockerCon Europe 2018
On December 3-5 I enjoyed my first DockerCon: With 2,200 attendees in Barcelona DockerCon Europe was about a third of DockerCon US in San Francisco with 6,000 attendees but still a large enough event. In its current state of building on open source roots and trying to make money from enterprise customers through their corresponding…

Setting up Windows Authentication with containers connected to Azure AD Domain Services
At DockerCon Europe 2018, Israel Vega from Microsoft and Steven Follis from Docker (@steven_follis) had a session called "Avoiding an identity crisis" talking about Windows / Active Directory authentication for containers. A really good introduction and also a lot of interesting information if you are already working with win auth in containers. For example I…

Voting Docker-Swarm-style and how it helped me at NAV TechDays
At NAV TechDays 2018 I was lucky enough to host two 1-day workshops and a session around Docker on Windows and Business Central on Docker. It really was great fun but during the first day of my workshop I noticed that getting feedback on when people were ready with the current topic wasn't easy. But…

Creating a multi-arch Docker image with Azure DevOps
Microsoft has rebranded and extended their SaaS ALM offering Visual Studio Team Services (VSTS) to Azure DevOps. I usually had an eye on what is happening with VSTS but as we are using an on-prem Team Foundation Server, I mostly don't have the hands-on experience, so this relaunch was a good reason do really dig…

Load Balancing NAV/BC in Docker Swarm
Tobias already explained how we can easily load balance the NAV Webclient via traefik. Load balancing the Windows client is a bit more complicated... TL;DR NAV uses TCP connections with a proprietary protocol for the Windows client communication and HTTP connections for the webclient and the webservices. Also the Windows and webclient require sticky sessions…

Bringing it together: Windows auth in a NAV/BC image in a Docker Swarm
I explained here that you can easily use gMSAs in a Docker Swarm to enable Windows authentication. I have only used a Windows Server Core image to show that it works, but of course the goal for me is running a NAV/BC image with a Windows authenticated WebClient in a Docker Swarm. If you are…

Windows authentication in Docker Swarm
As I very recently wrote, Windows authentication for Docker containers on Windows Server 2019 made a huge step in the right direction by losing the need for identically named containers and gMSAs. But that unfortunately will be reality only some time in the future and with Windows Server 2012 (R2) still very much in use…

Windows authentication in Docker containers just got a lot easier
Windows authentication in Docker containers is kind of a tricky subject and while containers in general are gaining momentum every day, containers on Windows are having a somewhat less steep increase and Windows authentication in that context is the niche in a niche. Still, that topic matters if you have users depending on Windows authentication…

NAV/BC Azure Container Instances with Let’s Encrypt certificates
If you just want to have a Dynamics NAV / BC environment up and running without caring for anything around it, Azure Container Instances might be a very good way to go. I've explained about that here and here. One of the main problems there was that you could only use unsecured http or a…

Automated testing of a Business Central Extension V2 in TFS
One of the requirements of publishing a Business Central app (extension V2) into AppSource is an automated test package. That obviously makes a lot of sense but how to get there is not an entirely clear path. Microsoft shares their example code and some guidelines here but creating the test code is only half of…

Get logs and execute commands on Azure Container Instances
Azure Container Instances (ACI) have recently reached GA and adoption and use cases have come up in a lot of places. Two examples of that would be my NAV/BC on ACI quickstart template and the API-enabled NAV instance on ACI you can create from my VS Code extension. Two very nice features have also been…

Quickly grant access to a user group when starting a NAV container
As we use Docker containers internally to quickly spin up environments for reproducing bugs, delivering fixes on older releases or quickly test our application, we needed a way to easily grant access to a specific Active Directory user group. When starting a container, we want the following actions to be taken: Create NAV user and…

Use GitHub to change how your NAV on Docker container works
With the addition of the new "folder" feature in the NAV Docker images it is now possible to download a .zip in the very beginning of container startup and extract it to a folder. That allows you to make changes to the container logic in about every aspect without the need to map a local…

Quickstart your D365/NAV Connect API usage: Use Azure Container Instances to go serverless and let ALRunner generate your client
You might have seen one of the presentations where Microsoft showed their idea of future NAV-based applications: It can be either a Connect App (just connects through a REST WebService API to D365/NAV), an Add-On App (adds functionality to D365/NAV through an extension) or an Embed App (deeply changes how D365/NAV works by embedding code,…

How to connect the NAV iPad App to your NAV Container using a self-signed certificate
As you probably know there is a very nice NAV App for iOS (and Android). For very good reasons this App however only connects to NAV WebClients secured by https. This is no problem using a NAV Container as it will by default also serve an https-secured WebClient. However if you don't use an official…

How to connect NAV on Docker to an existing SQL database (quick and dirty)
When Freddy Kristiansen, Jakub Vanak and I talked about NAV on Docker at NAV TechDays, the first two questions from the audience were "can I connect NAV on Docker to an existing SQL database?" But in a short answer we could only say "yes, absolutely" but not really explain it. (mehr …)

Use the VS Code Docker Extension with a remote Docker host
If you are a NAV developer working with Docker containers and the new dev environment aka VS Code (or for that matter anyone using Docker containers and VS Code), then you should very much look into the Docker extension for VS Code. It lets you see the registries you are using, the containers running on…

Continuous integration with AppVeyor and GitHub for NAV
Shipping software products has come a long way from "once every couple of years" to "your users might get a new feature in the next 5 minutes in your Cloud offering". And even if your market and your customers are not calling for such quick changes, as Marko Perisic very well explains here, being always…

Use Azure Container Instances for NAV
Running NAV inside a Container has many benefits but one of the probably most obvious ones when you start to work with it is the ease of deployment: Running a NAV container with SQL and WebClient embedded is as easy as docker run -e ACCEPT_EULA=Y navdocker.azurecr.io/dynamics-nav. But that assumes that you have Docker installed and…

Linux Containers on Windows
A tweet by Stefan Scherer (highly recommended follow!) made me aware, that with the latest Insider Preview of Windows Server you can run Linux Containers on Windows. Unfortunately his Vagrant box didn't work for me, very likely because of my severely limited Vagrant knowhow. Therefore I decided to set it up manually. As I probably…

You might have seen here that Microsoft NAV is now officially on it's way to support Docker / Windows Containers. The scope is not defined yet, but you can see the Dockerfiles here and if you contact Freddy Kristiansen you might get access to a Azure-based repository containing current images. Looking back nine months to…

Easily enter a Container through PowerShell
As I wrote here you can conveniently enter a running Container through PowerShell. As I am lazy (and hate doing repeating stuff) I created an additional function which makes it even easier. You could probably have done the same in five minutes but maybe it saves you at least those five… 🙂 With that in…

Using AD Accounts in containerized NAV and what I learned on the way

If you’ve worked with Windows Containers, you’ll probably know this, but I have to admit that I didn’t and it really helps to work conveniently with Windows Containers, especially reading and editing files: You can access a Container with Enter-PSSession. It works like this and I learned it from artisticcheese’s GitHub repo: First, install the necessary…

Better restore and less dependencies for containerized NAV (even for the upcoming release)
Again thanks to mainly Jakub Vaňák and a bit of work by myself you can now restore a .bak when your SQL container gets started and we’ve removed the identity framework dll (which isn’t working in a Container anyways). What does this actually mean? If you check the GitHub repo, specifically the docker-compose.configs.yml you now see the…

NAV 2017 on Linux – sort of
