Automated PowerShell Script v2.1 to Recreate My Business Central Docker Containers

 By Steve Endow


UPDATE:  I have posted version 3 of the script here


In July 2020 I posted an earlier version of this script.  This updated version has a few refinements, such as removing and importing BcContainerHelper to ensure the latest version is being used, adding Flush-ContainerHelperCache to remove old helper files, and removing old Docker images.

Automate, Automate, Automate

I setup a "Dev Container" task in Windows Task Scheduler to run this script every morning at 6:45am so that I always have a fresh BC container based on the latest BC artifacts.  I call my main Container "dev17", based on the current 17.x version of Business Central.  Do NOT name your container just "dev"--see my video here on why that will cause problems.

Changing the network location from Public to Private on Windows Server

By Steve Endow

This is just a post for me to store this information for Future Steve, as he will most certainly need it, just as Present Steve has needed it a dozen times over the last year.

Any time I replace my router, replace a piece of Ubiquiti network gear, or reconfigure my network, all of my Windows Server VMs decide they've been kidnapped and change their network location to Public network.

This blocks all traffic on the servers until I can login directly to each server and fix the problem.

Which requires an annoying process using gpedit or PowerShell, which I can never remember after 6 months.

So here is the post with the information to fix the problem:

https://serverfault.com/questions/639088/how-do-i-make-a-connection-private-on-windows-server-2012-r2

Using the GUI:

  1. Hit Winkey + R to open Run prompt and type gpedit.msc
  2. Navigate to: Computer Configuration/Windows Settings/Security Setting /Network List Manager Policies.
  3. Choose your Network name in the right pane.
    Note: To show networks not currently connected, right-click Network List Manager Policies in the left pane and choose Show All Networks.
  4. Go to Network Location tab and change the Location type from Public to Private.


Using PowerShell...

One line version:

Set-NetConnectionProfile -InterfaceAlias Ethernet -NetworkCategory Private

Multi-line version:

PS C:\>$Profile = Get-NetConnectionProfile -InterfaceAlias Ethernet1

PS C:\>$Profile.NetworkCategory = "Private"

PS C:\>Set-NetConnectionProfile -InputObject $Profile

Creating a simple text file using AL in Business Central - Sample Code

 By Steve Endow

On January 23, 2021, I recorded a video showing how to create a simple text file using AL in Business Central.


Here is the video:

PowerShell script to remove old Docker Images without deleting the base OS image

 By Steve Endow

If you are creating Business Central Docker Containers and regularly updating the artifacts and images for your containers, you may be familiar with this problem.

When you type "docker images" in PowerShell, you are greeted with a pile of old unused images consuming tons of disk space.

A digital junk drawer

I want to delete the old, unused Docker images.  But I do not want to delete the 10.4 GB "base OS" image that is listed at the very bottom.  As long as my OS version remains the same, that image can be used repeatedly, and if I deleted it, I would have to download it again.

Disable Browser Autofill with Business Central

 By Steve Endow

While using Business Central with Google Chrome, I started to notice strange words appearing in Business Central fields while I entered data in the browser.

Why are you doing this?

In this example, the word "test" was appearing when I clicked on the drop down list for bank accounts in Business Central.  The suggested value was in a text box displayed over the standard Business Central list box.

How many digits can a Business Central Amount field actually support?
