Had issues with docker for windows while bouncing around the network. This series of commands (as described here: http://stackoverflow.com/questions/32047660/docker-for-windows-not-working) seems to clear it up. ;docker reset
$dockerdir = "c:\program files\docker toolbox\"
RunWait("cmd /c docker-machine regenerate-certs -f default" , $dockerdir)
RunWait("cmd /c docker-machine restart default" , $dockerdir)
RunWait("cmd /c docker-machine env default --shell=cmd" , $dockerdir)
RunWait("cmd /c FOR /f " & '"' & "tokens=*" & '"' & " %i IN ('docker-machine env default --shell=cmd') DO %i")
RunWait('"C:\Program Files\Git\bin\bash.exe" --login -i start.sh' , $dockerdir)
