The, run the image:
docker run -d -p 1433:1433 -e sa_password=P@ssw0rd -e ACCEPT_EULA=Y -v C:/temp/:C:/temp/ -e attach_dbs=”[{‘dbName’:’NorthWind’,’dbFiles’:[‘C:\\temp\\NORTHWND.mdf’,’C:\\temp\\NORTHWND.ldf’]}]” myserversql

Obtain the ip address using:
docker ps -a

Take the first item and ask for IP :
D:\Dev\DockerSQL>docker inspect -f “{{ .NetworkSettings.Networks.nat.IPAddress }}” 7dfe63dd7615

Then open the SQL Server Management Studio and connect to this IP. You’re done !

It’s my birthday !

I turn 44 this September 1 so, on every Facebook notification I receive, I recall my friends I am a developer:

Did you say “it’s ugly ?” 😊

It’s C coded the ASM way ! 😊

How to make a dockerfile for running Windows Services

To run a Windows Service into Docker for Windows, you have to take some actions…

First you need to create the service. Use the sc.exe command. Make your service starting as auto. It will be running automatically.

If you need to start as an administrator to have admin privileges, use the sc sdset command:

RUN sc sdset SCMANAGER D:(A;;CCLCRPRC;;;AU)(A;;CCLCRPWPRC;;;SY)(A;;KA;;;BA)S:(AU;FA;KA;;;WD)(AU;OIIOFA;GA;;;WD)

It’s weird and ugly but it works !

A tip & trick: ask docker to start an OS image that ships IIS to be able to see your custom log files. Else, you can’t see what’s happening…

If you run your docker image in Azure Container Instance, be carefull that your image need to be a Windows Server 1609…

So I start theses images in my various dockerfiles:

  • FROM microsoft/dotnet-framework:4.6.2-runtime-windowsservercore-ltsc2016
  • FROM microsoft/aspnet:4.6.2-windowsservercore-ltsc2016

My log file is written in c:\temp\logs so I make a custom WebApp on tis folder:

RUN powershell.exe New-WebVirtualDirectory -Site ‘Default Web Site’ -Name Logs -PhysicalPath ‘c:\temp\logs’

With this kind of dockerfile, I can see the log file of my Windows Service and communicate with him:
