Openshift 4.6 on vSphere Prerequisites

-

In OpenShift Container Platform version 4.6, you can install a cluster on your VMware vSphere instance by using the installer-provisioned infrastructure.

Prerequisites

  • Provision persistent storage for your cluster. To deploy a private image registry, your storage must provide ReadWriteMany access modes.

  • Ensure that your vSphere server has only one data center and cluster. If it has multiple data centers and clusters, it also has multiple default root resource pools, and the worker nodes will not provision during installation.

That is where I stopped. What small environment do Openshift developers live in? 
I mean sure vSphere 7 can now handle a 96 node cluster, but surely if you are running Openshift on vSphere you have a larger environment.

vRealize Automation 8 - Migration Assistant - Entitlements

-
While assessing the migration to vRA8 most definitely you will run into deprecated entitled actions or extensions. A lot of the internal VMware Actions or Extensions are no longer valid, here is a small list of common ones: Connect using SSH Connect using VMRC Connect using RDP Execute Reconfigure Cancel Reconfigure Scale In Scale Out Power Cycle ... A dirty quick fix is to loop all your entitlements before running the migration assistant and remove all of these deprecated if you do not depend on anyone using them in your vRA7 environment. var entitlements = Server.findAllForType("vCACCAFE:Entitlement"); for each (var entitlement in entitlements) { System.log(entitlement.name); var updated = false; var host = vCACCAFEEntitiesFinder.getHostForEntity(entitlement); var client = host.createCatalogClient().getCatalogEntitlementService(); var entitledResourceOperations = entitlement.getEntitledResourceOperations(); for each (operation in entitledResourceOperations) {

vRealize Orchestrator and Microsoft Powershell Double Hops

-
Recently started automating Microsoft DNS and the best way in seems to be through Powershell . One of the common ways to deal with this is through a Powershell Host defined in vRO. You set it up securely with HTTPS and Kerberos and specify the credentials of a user with DNS server rights enough to see and manipulate the content of the zones and records you want to automate. So far so good, and you start developing the PowerShell commands you might need. Resolve-DnsName (Get-ADDomain).DNSroot -type ns | ? {$_.type -eq "A"} | select name,Address,IP4Address,IPAddress | ConvertTo-Json -depth 1 -Compress Get-DnsServerZone -ComputerName (Get-ADDomain).DNSroot Get-DnsServerResourceRecord -ComputerName (Get-ADDomain).DNSroot And they all work out nicely when you run them from your Powershell host, but once you run them from vRO in the Powershell session you run into the double-hop auth problem . There are many ways to deal with this, but often you need to thinker both with the Powers

vRealize Orchestrator - SSH Keys - Idea for how to easy manage multiple keys

-
Many are using SSH to run commands something similar to  var  passwordAuthentication = false; var password = ''; var session = new SSHSession(hostName, username, port); session.connectWithPasswordOrIdentity(passwordAuthentication, password, path); Where the path leads to the private key file for the connection. Storing several key files in the vRO filesystem could easily lead to forget it when moving to a new vRO or add a new vRO node. Also when moving forward with vRO 8 it's less of a good idea to add elements to the local filesystem as a manual step. My suggestion for a solution is to make use of the vRO resource element. Store your key file as a vRO resource element, using the following step of code can runtime make the key available for SSHSession. var tempDirectory = System.getTempDirectory(); filePath =  tempDirectory + "/" + keyfile.name; keyfile.writeContentToFile( filePath ); Send the private key file as a resource to the action or workflow and you will h
