The DNSserver module for remote administration of Windows DNS servers does not appear to be available on powershell for Linux, as indicated by this error:
PS /home/gmonkey> Install-Module -Name DnsServer -Scope CurrentUser
PackageManagement\Install-Package : No match was found for the specified search criteria and module name ‘DnsServer’. Try Get-PSRepository to see all available registered module repositories.

"We can proxy commands that you type and run and they will run on the remote machine. You'll be able to manage everything from everywhere," he explained. https://www.theregister.co.uk/2016/08/18/microsoft_brings_powershell_to_linux_and_mac_publishes_as_open_source
Most of the modules that ship as part of Windows (for example,DnsClient, Hyper-V, NetTCPIP, Storage, etc.) and other Microsoft products including Azure and Office have not been explicitly ported to.NET Core yet. The PowerShell team is working with these product groups and teams to validate and port their existing modules to PowerShell Core. With .NET Standard and CDXML, many of these traditional Windows PowerShell modules do seem to work in PowerShellCore, but they have not been formally validated, and they are not formally supported.
They are all working to correct that, but no date when it will happen.
Even on Windows, unless you add the compatibility packs, PSCore does not have any of the RSAT cmdlets, you have to revert back to v1 language, using the .net namespace.
A quick option is to set up PowerShell Web Access on a remote Window’s server or Windows 8+ workstation and use your browser to PS stuff.
