Problems Uploading to WebServer

Hello Community,

My very first post here - my first foray into Chef.

I have been using the following document: Automating Azure virtual machine deployment with Chef

https://docs.microsoft.com/en-us/azure/virtual-machines/windows/chef-automation.

I have come across the following stumbling block with the error message:

PS C:\chef> knife cookbook upload webserver WARNING: No knife configuration file found ERROR: Could not find cookbook webserver in your cookbook path, skipping it WARN: Failed to read the private key C:\chef\client.pem: #<Errno::ENOENT: No such file or directory @ rb_sysopen - C:\chef\client.pem> ERROR: Your private key could not be loaded from C:\chef\client.pem Check your configuration file and ensure that your private key is readable

I have installed the server and followed the instructions as best as I could. Can someone please let me know where I might be going wrong?

Thanks

Carlton
