I'm building a Docker image based from microsoft/powershell:ubuntu16.04. It builds properly without any error, however when I go to use it it doesn't have the imported module that I stated in the Dockerfile (which is a psd1 file from a GitHub repo cloned in the image.
I tried with a simple import of Microsoft's powershell management as well (seen below), and it also doesn't get imported. I ran the image interactively and the commands one by one and everything imported fine, so I don't know why it doesn't work through the Dockerfile build itself.
FROM microsoft/powershell:ubuntu16.04
WORKDIR /workdir
RUN pwsh -command "Import-Module Microsoft.PowerShell.Management"
CMD [ "pwsh", "-Command", "Get-Module" ]
