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.

vRA7 to vRA8 migration - Orchestrator

Steps to get up and running with vRO 8. Depending on your previous usage of vRO 7 this might the step that requires the most work when you are migrating to vRA8. Attribute Parameter Contains vCAC/vCACCAFE type! cafeHost|vCACCAFE:VCACHost| Switch to vRealize Automation 8 Types Input Parameter Contains vCAC/vCACCAFE type! subtenant|vCACCAFE:Subtenant Switch to vRealize Automation 8 Types Input Parameter Contains Payload Properties! payload|Properties Ensure the selected properties are supported by vRealize Automation 8 The first two will be quite common for everyone who has automated vRA7 using the vRA Plugins for vCAC and vCACCAFE the only working rewrite here is to move to the REST API and redo the work directly. The last one is also heavily used by everyone who relies on the Subscriptions both by pick up information in vRO and sending information back to vRA with " virtualmachineAddorUpdateProperties ". With just about 190 workflows to redo/rewrite or so i gues...

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...

Possible pitfall - duplicate config_admin users - Using vRSLCM as deployment engine

-
Bilde
Some days ago as vRA 8.2 Patch 1 came along we decided to create a new test environment to see the upgrade process. It went rather smoothly as this is not the first environment to be deployed with vRSLCM. Few minutes of prepare vRSLCM and deployment went good, logging on to the new environment and then proceeded to install vRA 8.2 Patch 1.  https://docs.vmware.com/en/vRealize-Automation/8.2/rn/vRealize-Automation-82-releasenotes.html Now all went rather smoothly and we were please with the result. Sometime during the few last days also vIDM was patched to 3.3.3 https://docs.vmware.com/en/VMware-Workspace-ONE-Access/3.3/rn/VMware-Identity-Manager-333-Release-Notes.html And all of a sudden we lost access to our little test environment. As it was only there to test the upgrade patch 1, it was not a large issue, but strange never the less. In this test environment, we did not set up any other access roles, besides the default config_admin user. We could log in with it, but we had no ac...
