Host Cannot Download Files From VMware vSphere Update Manager Patch Store

You may see following error when you scanning ESXi hosts by vCenter Update Manager.
Host cannot download files from VMware vSphere Update Manager patch store. Check the network connectivity and 
firewall setup, and check esxupdate logs for details.

You also see similar logs in /var/log/esxupdate.log.
[Errno -2] Name or service not known

The root cause could be following:

  1. ESXi host cannot resolve DNS name of vCenter Update Manager Server.

  2. One of the DNS servers incorrect if you set multiple DNS servers on ESXi host.

Connect-NsxtServer shows "Unable to connect to the remote server"

When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false

Setup Terraform and Ansible for Windows provisionon CentOS

Provisioning Windows machines with Terraform is easy. Configuring Windows machines with Ansible is also not complex. However, it's a little bit challenging to combine them. The following steps are some ideas about handling a Windows machine from provisioning to post configuration without modifying the winrm configuration on the guest operating system.

How to List All Users in Terraform Cloud

Terraform has a rich API. However, the API documentation does not mention how to list all users. We can leverage the organization membership API and the PowerShell command  Invoke-RestMethod  to get a user list. 1. Create an organization token in Terraform Cloud. 2. Create the token variable ( $Token ) in PowerShell. $Token = "abcde" 3. Create the API parameters variable in PowerShell. $params = @{ Uri = "https://app.terraform.io/api/v2/organizations/ZHENGWU/organization-memberships?page%5Bsize%5D=100" Authentication = "Bearer" Token = $Token ContentType = "application/vnd.api+json" } Note: You need to replace ZHENGWU with your own organization name. And I used 100 at the end of the URI to retrieve the first 100 users. It can be any number.  4. Retrieve the API return and list the user's email address. $Test = Invoke-RestMethod @params $Test.data.attributes.email
