VMware PowerCLI on Powershell Core

I recently installed Powershell Core om Ubuntu 18.04, and after installing the PowerCLI module. I ran into an error.

The error is not an uncommon one, but on Windows the error message makes a lot more sense, so I just wanted to let you know what this error actually means.

The error you might get when you try to connect to your vCenter server using the connect-viserver is the following:

Connect-VIServer : 9/27/18 10:41:37 AM	Connect-VIServer		The SSL connection could not be established, see inner exception.	
At line:1 char:1
+ Connect-VIServer <servername>
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : NotSpecified: (:) [Connect-VIServer], ViError
+ FullyQualifiedErrorId : Client20_ConnectivityServiceImpl_Reconnect_SoapException,VMware.VimAutomation.ViCore.Cmdlets.Commands.ConnectVIServer

The only hint here is “The SSL connection could not be established…”

This actually means that you do not have a valid certificate. And if you want to connect to vCenter without a valid certificate, you have to allow this.

You can either change you vCenter certificate to a trusted one, which is the correct solutions or you can ignore invalid certificates, which circumvents all security, but makes it work right now.

Set-PowerCLIConfiguration -InvalidCertificateAction:ignore
