Trouble with MSI installer in container

[jghal]

I'm trying to build a custom image with the CLI installed and there is an issue with installing the MSI. My Docker host is on Windows Server 2019.

FROM mcr.microsoft.com/dotnet/framework/sdk:4.8

SHELL ["powershell", "-Command", "Continue = 'Stop'; SilentlyContinue = 'SilentlyContinue';"]

RUN Invoke-WebRequest -Uri "https://awscli.amazonaws.com/AWSCLIV2.msi" -OutFile "AWSCLIV2.msi" -UseBasicParsing ; \
    Start-Process -Wait msiexec.exe -ArgumentList @('/i', 'AWSCLIV2.msi', '/qn', '/L*v', 'C:\\install.log') ; \
    Remove-Item -Force AWSCLIV2.msi

ENTRYPOINT ["signtool.exe"]

I think it's not really waiting for the install to complete. The build output looks ok

docker build -t code-sign:initial .

But the resulting image doesn't seem to have the CLI installed, or the log file from the installer

But if I run the same commands from the dockerfile to manually download and run the MSI installer inside a container and wait a few minutes then it works.
