As mentioned in this blog post, the Invoke-ScriptInBcContainer has undergone some serious changes in BcContainerHelper 3.0.9, which just shipped.

This blog post will describe some details about how this function works.

The function takes a containerName, a scriptblock and an argument list as parameters and will execute this scriptblock inside the container.

Telemetry in BcContainerHelper 3.0.0

BcContainerHelper 3.0.0 just released and as something new, you will see this message when importing the module:

BcContainerHelper emits usage statistics telemetry to Microsoft

What does that mean? Can you avoid that? Who can access the emitted telemetry data? How? Can you use telemetry for troubleshooting? Can you use telemetry for other things?

This blog post will try to answer these questions.

Trojan Warning when creating Containers…

UPDATE: with defender update 1.353.1128.0 or later, this false positive is no longer.

With the latest update to Windows 11 and defender, my computer is telling me that I have a Trojan Virus every time I create a container.

Well, I don’t – it is a false positive and there is probably no good workaround possible.

An update to the ARM templates

It’s been a while since I last blogged about the ARM templates. Mostly because they just live a life of their own and just works. An average of 20 times a day, some partner somewhere in the work is using to create an Azure VM with Business Central running in a container (or one of the other ARM templates) directly from a browser. On top of this are all the partners who are automating the process of creating Azure VMs with a PowerShell script. A few things are changing, but functionality stays the same.

Troubleshooting Business Central on Docker

This blog post is not really a troubleshooting guide (although there is a small TSG at the end). It is more like a brain dump of what I have seen over time and how I would approach a trouble shooting session. I have divided it into 6 sections:

  1. Dockers worst enemy (just FYI)
  2. Installing Docker
  3. Installing BcContainerHelper
  4. Creating a Business Central container
  5. Keep the script, not the Container
  6. Frequently seen docker errors

Going forward, I will add a link to this blog post to all issues on, where the answer to the issue is in this blog post.

One of these days…

Many years ago, I heard a joke:

3 people (a biologist, a mathematician and a developer) were in Africa on a Safari. They drive by a blue elephant. The biologist shouts out: “Look, there is a BLUE elephant.”. The mathematician states: “Right you are, there is ONE blue elephant”. The developer slaps his palm against his forehead and says: “Damn, there are blue elephants…

New-BcContainerWizard aka Business Central on Docker script generator…

Update 2021/2/10: BcContainerHelper has replaced NavContainerHelper. This blog post still reference NavContainerHelper, which is outdated.

I have been wanting to create a repository of scripts, where you could locate the right script for your usage. The problem I ran into was however that the number of scripts in a repository like that would very quickly explode. Yesterday evening while riding my bike, I got an idea…

Why not create a script generator script for Business Central on Docker. A script, which asks you a lot of questions and then generates a script, which you can save and run.
