Install Powershell and PowerCLI in Ubuntu 18.04 (Bionic Beaver) – Unsupported Workaround

EDIT: This was an unsupported work around and now 18.04 is officially supported, you can read my post about it here: Install Powershell and PowerCLI in Ubuntu 18.04 (Bionic Beaver)

Over the last few weeks, due to the increased compatibility and requirements for me to be using a Linux distro, I have decided to make a transition over to Linux (specifically Ubuntu) and one of the requirements for this process was the ability to install Powershell as I frequently use PowerCLI. However, It’s not as simple as an apt-get install cmdlet. I am by no means a developer or coder, but as you might know, I do create some scripts or tools now and again.

So, as part of this trial transition (who knows, might go back to windows – ghast!), I have managed to install Powershell and PowerCLI. This guide is for 18.04 but it uses 17.04 libraries as 18.04 is not official supported, yet. But it does work.

So, lets begin:

Clone Datastores from one ESXi host to Another

As we I progress with our server refresh and I continue to build our global virtualised infrastructure, I am constantly trying to make things easier for my less experienced colleagues and so that there will be consistency in what we do. One of the most tedious tasks must be NFS datastore creation. While we could script this out and create each datastore individually, I figured I would try find a way clone the datastore configuration from one host to another. This way you simply execute the script and let it run along, giving you time for other cool stuff.

This little script will save you hours, especially if you have hundreds of datastores and hosts.

Script 1: This is for host to host clone only

$Source_Host = Read-Host "Enter The Source Host"
$Destination_Host = Read-Host "Enter the Destination Host"
$Source_Root_Password = Read-Host "Enter Root Password for Source Host"
$Destination_Root_Password = Read-Host "Enter Root Password for Destination Host"
Connect-VIServer -Server $Source_Host -User root -Password $Source_Root_Password
Connect-VIServer -Server $Destination_Host -User root -Password $Destination_Root_Password
foreach (
			$datastore in (Get-VMhost $Source_Host | Get-Datastore | where {$_.Type -eq "nfs" -and $_.Accessible -eq "true"})
			New-Datastore -VMhost $Destination_Host -Nfs -Name $datastore.Name -Path $datastore.RemotePath -NfsHost $datastore.RemoteHost
Disconnect-Viserver * -Confirm:$false

Script 2: This for host to Cluster wide .

$Source_Host = Read-Host "Enter The Source Host"
$Destination_vCenter = Read-Host "Enter the vCenter you want to connect to"
$Cluster = Read-Host "Enter the name of the Cluster to connect to"
$Source_Root_Password = Read-Host "Enter Root Password for Source Host"
Connect-VIServer -server $Source_Host -user root -password $Source_Root_Password 
Connect-VIServer -server $Destination_vCenter
foreach (
			$datastore in (Get-VMhost $Source_Host | Get-Datastore | where {$_.Type -eq "nfs" -and $_.Accessible -eq "true"})
			Get-Cluster "$Cluster" | Get-VMhost | New-Datastore -Nfs -Name $datastore.Name -Path $datastore.RemotePath -NfsHost $datastore.RemoteHost
Disconnect-Viserver * -Confirm:$false

Copy the above text in to a text document and save it as a ps1 (powershell) file and run it using PowerCLI.

Finding Groups that have disabled users in them

This is just a quick powershell script to find all users who are a member of a certain group (of certain groups).
We were running out of licenses for one of the products we use internally. This product is tied to group memberships. Instead of clicking on each indivual group or disabled user (approximate 40 groups or 560 disabled users), I figured I would draft up a quick powershell to do the work for me.
