AWS PowerShell Lambda Build Environment for Docker

If you’re deploying an AWS PowerShell Lambda (which is PowerShell Core 6.0) in a build pipeline, you’ll likely come across the fact that the older PowerShell docker images don’t have Dotnet Core installed.

The .NET Core 3.0 .NET Core 3.0 SDK Docker images now contain PowerShell Core, but since AWS still uses .NET Core 2.1 which is in Long Term Support, you’re out of luck.
