Installing Docker onto Windows Server 2016

 

https://docs.docker.com/install/windows/docker-ee/

Docker comes in two editions, free community edition and enterprise edition.

The company Docker and Microsoft entered into a commercial agreement to bring Docker to windows server as a commercially supported container enterprise product.

Docker running containers on Windows is the result of a two-year collaboration between Microsoft that involved the Windows kernel growing containerization primitives, Docker and Microsoft collaborating on porting the Docker Engine and CLI to Windows to take advantage of those new primitives and Docker adding multi-arch image support to Docker Hub. (https://blog.docker.com/2016/09/dockerforws2016/)

 

 

As a result of the agreement Docker Enterprise is already licenced as part of Windows Server 2016. So you just need to install and use it!

 

There are two types of containers, Linux and Windows. To run Windows OS containers, you must install the windows provider. Choose the appropriate container type below and issue the relevant commands.

For Install for Windows containers:

Install-Module -Name DockerMsftProvider -Repository PSGallery -Force

Install-Package -Name docker -ProviderName DockerMsftProvider

For Install for Linux Containers:

Install-Module DockerProvider –Force

Install-Package Docker -ProviderName DockerProvider –Force

 

When installed there will be a Docker Service on the machine:

Docker Service

When the command has finished executing (can take some time), then powershell should be aware of Docker commands. Thus issuing the following command:

Docker version

will return information about the Docker version.

Docker Version

 

Uninstall docker from Windows Server 2016

Uninstall-Module dockerprovider

Uninstall-package docker

or for windows container:

Uninstall-Module DockerMsftProvider

Uninstall-package docker

Dynamics GP 2018 wrong version of GP2018 Power Shell included

Be aware of an issue with the GP2018 installation media

GP2018 Power Shell Additional Product is version 2016

You can see above that the installation media MDGP2018_RTM_DVD_ENUS has under the Additional Products the GP2016 installer for Power Shell.

The correct installer has been provided by Microsoft under Customer Source here: https://mbs.microsoft.com/customersource/northamerica/GP/downloads/service-packs/mdgp2018_dexterityreleases

It is not obvious that a administration module should be under something as specific as Dexterity Development System – buy hey at least it IS available!


Dynamics GP 2018 Power Shell installer found under Dexterity Development System Releases for Dynamics GP 2018

Printing to multiple UPS label printers (from Dynamics GP)

This is a quick note to self:

When an order is fulfilled it is routed electronically to the appropriate carrier depending on nature of the consignment.

The various carriers we use then print the thermal shipping label directly to the warehouse packing bench that is fulfilling that order. With one central thermal label printer an many benches, it is both ergonomically inefficient and too error prone (wrong labels get on wrong parcels).

 

UPS world ship

UPS Worldship allows printers to be defined and named within the world ship software. The printer can be one that is a network printer or a shared printer from another machine.

Each warehouse packing bench has a shared (or network) printer placed on it. Each of these printers is set up in WorldShip with the bench name (BENCH1..2…3..)

The GP fulfilment then sends that printer name of the bench that machine is on, within the XML for the despatch. The Worldship auto XML import picks up that printer name. That ensures that when the shipment is processed, the labels are routed to the originating warehouse packing bench thermal printer.

Drivers

UPS use a bespoke driver for the Zebra thermal printers. In fact they even have their own badged version of the Zebra printers with UPS firmware on. This lets them get the fonts and layout of their label correct, so if using a non-UPS Zebra thermal printer you must install the UPS drivers on the machine and go into the printer settings and replace the stock driver with the UPS one. This works even for old DA402 up to the more modern GK series printers.

If you are putting your own logo on the UPS labels by using the custom label templates within Worldship, and thus are using the extended size label stock, you must also ensure that you use the zebra printer media calibration, found in the printer settings tools section to calibrate the printer stock size.

 

Thus we can now fulfil orders on many warehouse packing benches with one Worldship instance and thermal labels will print on the correct bench’s thermal printer.

Converting Dynamics GP SOP Master numbers to file system folder hierarchy

There are a number of cases where I need to store a document or documents against an “object” in GP for the various system integrations and modifications. This can be problematic, even more so with the latest update to Windows 10 that seemed to seriously detrimentally affect the performance of folders with large numbers of files or subfolders in them. Take the SOP document in GP. SOP documents are threaded together via a relationship called the master number. This master number relates all documents together between quote, order, invoice, return.

It is appropriate in some cases to store files against those master numbers. This could be done in a flat structure where a documents folder contains a sub folder for each master number and in side those folders lie the documents we wish to preserve. This starts out great, however by the time you end up with 500,000 sales master numbers and documents, opening the network store folder starts taking up to three to four minutes.  Although anything over a few thousand files or subfolders in a folder has always incurred a performance hit, with the new update this seemed to get a whole lot worse (it felt like a caching issue as subsequent re-opening of folder happened instantaneously).

Storing all those folders in a single folder is not a good user experience either, it is overwhelming to try and find a folder of interest among all those folders. A much better way is to store the folders in a hierarchy so there are never more than 1000 folders in each sub folder. This keeps the file system happy and quick.

 

So how to migrate the flat structure to hierarchy?

 

I love powershell and wish I could script in it more fluently than I can. Powershell seems to have the power to address any mundane task to do with windows servers and clients. Using power shell it is possible to move the flat structure into a new root directory, building it up into a hierarchy. My preference is for each folder to intuitively orientate the user as to where they are without having to digest/process too much of the path information.

There are lots of options for a directory arrangement scheme, but I like to do as follows, for a master number of 13224223, the folders can be organised like this:

\\SalesArchive\13220000\13224000\13224200\13224223\

This then necessitates a way to transform the number 13224223 to this directory arrangement. This is something regular expressions can help with, I’ve been using this technique for many, many years now.

Regular expression:

([0-9a-zA-Z]*)([0-9a-zA-Z]{1})([0-9a-zA-Z]{1})([0-9a-zA-Z]{2})$

Replacement expression:

${1}0000\${1}${2}000\${1}${2}${3}00

So integrating this into our powershell with optional date limit we get the following…

$sourcePath = "\\SalesArchive\"
$destPath = "\\SalesArchive\New\"
Write-Debug($destPath)
Get-ChildItem "$sourcePath\*" |? {$_.psiscontainer -and $_.lastwritetime -le (get-date).adddays(0)} |%{
if($_.Name -ne "New" -and $_.Name -ne "New2"){
$newFolder = ($destPath + "\" + ($_.Name -replace '([0-9a-zA-Z]*)([0-9a-zA-Z]{1})([0-9a-zA-Z]{1})([0-9a-zA-Z]{2})$','${1}0000\${1}${2}000\${1}${2}${3}00'));

New-Item -Path $newFolder -Type Directory -Force
Move-Item $_ $newFolder
Write-Host "source: $sourcepath dest: $newFolder"
}
}

This will move the folders into the new shape for us.

In .NET we can also use the same regular expression to open the folder or fetch/save files but using the .NET regular expression library something like this:


Return RootFolder & System.Text.RegularExpressions.Regex.Replace(DocumentMasterNumber,
"([0-9a-zA-Z]*)([0-9a-zA-Z]{1})([0-9a-zA-Z]{1})([0-9a-zA-Z]{2})$",
"${1}0000\${1}${2}000\${1}${2}${3}00")

Working things this way lets users access the folders instantly again and makes manual navigation of the folder structure possible, should it be needed.
