Docker keep powershell environment changes
So,
I have found a workaround for this, basically you want to create a powershell profile at the start of the container, which will get run everytime the RUN command is used..
To do this, I did the following :
RUN mkdir C:\Users\ContainerAdministrator\Documents\WindowsPowerShell ;
RUN New-Item C:\Users\ContainerAdministrator\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 -Type file -Value 'Set-DNSClient -InterfaceIndex 5 -ConnectionSpecificSuffix my.dns.suffix ;'
This will make sure that everytime I run a command it will execute the Set-DNSClient on opening a powershell session.
Hope this helps someone.
