Powershell to create labs from CSV

[bbuchanan]

I wrote this little script to create labs from a couple of CSV files. I made this after reformatting my surebackup host a second time and it was getting tedious to recreate all the labs. It's written to make it easy to copy/paste sections into powershell, there are probably better ways to write this. One CSV contains the Lab definition and the second CSV contains the network mappings for each lab.

If there's a better version floating around please direct me to it and I'll delete this.

I haven't tested the sample data in the csv below, hopefully I didn't make any typos.

Code: Select all

Virtual Labs.csv
LabName,LabDescription,LabHostName,LabDataStorename,ApplianceName,AppliancePoolname,ApplianceFolderName,ApplianceProductionNetworkName,ApplianceIPAddress,ApplianceSubnetMask,ApplianceDefaultGateway,AppliancePreferredDNSServer,ApplianceAlternateDNSServer
A_Lab,Lab for SureBackup of A,vmwarehostforveeamsurebackup.example.com,datastore1,A_Lab,A Lab,A Lab,VM Network,10.1.1.2,255.255.255.0,10.1.1.1,8.8.8.8,8.8.4.4
B_Lab,Lab for SureBackup of B,vmwarehostforveeamsurebackup.example.com,datastore1,B_Lab,B Lab,B Lab,VM Network,10.1.1.3,255.255.255.0,10.1.1.1,8.8.8.8,8.8.4.4

For IsolatedMasqueradeAddress I've been counting up from the high bit to avoid surprises when a production network is bigger than a /24, eg. 0, 128, 64, 192, 32, 160, 96...
