Created an image for .Net Core 3.1 x86 from windows servercore base image. It works fine when tested it locally on my windows machine. 

Here is the bitbucket-pipelines.yml file:

# You can specify a custom docker image from Docker Hub as your build environment.
image: nagasreeatsymphony/fromservercore

options:
  max-time: 50
pipelines:
  default:
    - step:        
        #SAAIDI APIs
        - export SLN_NAME=SAAIDI-API/SAAIDI
        - export TEST_NAME=SAAIDI.InterationTests/SAAIDI.InterationTests
        - export CONFIGURATION=Release
        - export RUNTIME=win-x86
        - dotnet restore $SLN_NAME.sln
        - dotnet build --no-restore $SLN_NAME.sln --configuration $CONFIGURATION --runtime $RUNTIME
        - dotnet test $TEST_NAME.csproj --configuration $CONFIGURATION --runtime $RUNTIME

I have a .Net Core WebAPI project built as x86. I have to use .Net Core 3.1 x86 SDK to build and test the projects successfully.  

When using .Net Core 3.1 official image from Docker Hub, getting this error
