How to use Docker SQL Server for Windows Server 2019

No Comments

Microsoft has not released Docker images for SQL Server for Windows Server for almost 3 years. However, since I am essentially working with Windows Server 2019 and Azure, I am sharing a script to create a local image. As a user you therefore have to help yourself.

The image is created automatically by my script based on Microsoft’s code (https://github.com/Microsoft/mssql-docker).

This is basically what happens:

  1. The source code from Microsoft for building the image is temporarily downloaded.
  2. The base image in the Dockerfile is replaced with Windows Server 2019.
  3. The image is created and tagged.
  4. The temporary folder is removed again.

The Script
https://github.com/svengrav/devops-lab/blob/main/powershell/New-SQLServerImage.ps1

# Base Image for Windows Server 2019
$Image = "mcr.microsoft.com/windows/servercore:ltsc2019"
$Tag = "my/sqlserver"

# Create Image
$SourceDir = (New-Item -Path (Join-Path $env:TEMP (New-Guid)) -ItemType Directory).FullName
$Archive = Join-Path $SourceDir "Source.zip"
$RepositoryUrl = "https://api.github.com/repos/microsoft/mssql-docker/zipball/master" 

Invoke-RestMethod -Uri $RepositoryUrl -OutFile $Archive
Expand-Archive -Path $Archive -DestinationPath $SourceDir -Force
Remove-Item $Archive

$DockerDir = Join-Path $SourceDir "microsoft-mssql-docker*\windows\mssql-server-windows"
if(Test-Path $DockerDir) {
    $DockerDir = Get-Item $DockerDir
    $DockerFile = Get-Content (Join-Path $DockerDir dockerfile) 

    $DockerFile -Replace "FROM microsoft/windowsservercore", "FROM $Image" | `
        Set-Content (Join-Path $DockerDir dockerfile) 

    docker build -t $Tag $DockerDir.FullName
}

Remove-Item $SourceDir -Recurse -Force

# Run
# docker run --name "sqlserver" -d -p 1433:1433 -e sa_password="" -e ACCEPT_EULA=Y my/sqlserver

You can start the SQL Container with:

docker run --name "sqlserver" -d -p 1433:1433 -e sa_password="" -e ACCEPT_EULA=Y my/sqlserver
