get a sql server (express) during a pipeline build azure devops - azure-devops

Question

i'm setting up a pipeline for asp.net application. During integration tests task i need to connect to a SQL server. How can i say to the pipeline that i need a sql service ?
I have tried with multiple microsoft hosted agent pool (Windows Server 1803, Hosted 2017 & 2019)
I use Windows Server 1803 and issue is:
The operating system of the container does not match the operating system of the host.
I would like setting up correctly a temporaly sql server to running tests.
I have used localdb instead.
i run this script before my intregration tests task
SqlLocalDB.exe create "DeptLocalDB"
SqlLocalDB.exe share "DeptLocalDB" "DeptSharedLocalDB"
SqlLocalDB.exe start "DeptLocalDB"
SqlLocalDB.exe info "DeptLocalDB"
To connect with powershell: Invoke-Sqlcmd -Query "SELECT GETDATE() AS TimeOfQuery;" -ServerInstance "(localdb)\.\DeptSharedLocalDB"
To connect with sqlcmd: sqlcmd -S (localdb)\.\DeptSharedLocalDB
To connect a c# app (connectionString): "Data Source=(localdb)\.\DeptS
haredLocalDB;Initial Catalog=DeptLocalDB;Integrated Security=True;"
If someone know how to mount a sql server in a container on azure pipeline, it will be appreciated. Thank for reading

Answer 1

Chocolatey is installed on windows-latest.
So, if you in you YAML file define:
pool:
vmImage: windows-latest
you can then install SQL Server Express using choco:
- script: choco install sql-server-express

Answer 2

azure-pipelines.yml:
pool:
vmImage: 'windows-latest'
...
- task: PowerShell#2
displayName: 'start mssqllocaldb'
inputs:
targetType: 'inline'
script: 'sqllocaldb start mssqllocaldb'
After the following connection string is valid:
Data Source=(localdb)\\MSSQLLocalDB;Initial Catalog=my-db;Integrated Security=True;

Answer 3

In my case (some .NET Core integration tests that needed LocalDB), just using the windows-latest image did the job:
pool:
vmImage: 'windows-latest'
The image comes with Visual Studio which includes LocalDB.

Answer 4

Here a full example of how I achieved running Integration tests using Sql Express in Azure Devops. I had to use the YAML based pipelines so I could use simonauner's approach using Chocolatey to install Sql Express. Make note that I had to install EF Core tools since I use .Net Core 3.1 in this pipeline. Also note that I generate an EF Code First migration SQL file on the fly so that the rigged SQL Express instance is filled with contents.
Deploy SQL Express instance in Azure Devops, install and generate and run EF Code first migration sql script to update database with schema and seed data using EF Code First tools.

Answer 5

I need localdb in order to run database unit tests, and I also require at least SQL Server 2016 SP2 because my team is using some of the newer language features.
On a windows-2019 image, simply use choco or powershell to execute the following command:
choco upgrade sqllocaldb
