Why use Content Libraries with vRA 8 Product Version - vRealize Automation 8.x What are vSphere Content Libraries? A content library stores and manages content in the form of library items. A single library item can consist of one file or multiple files. For example, the OVF template is a set of files (.ovf, .vmdk, and .mf). When you upload an OVF template to the library, you upload the entire set of files, but the result is a single library item of the OVF Template type.

Using vRealize Orchestreator MP in vROps Product Version - vRealize Operations 7.x and 8.x A few years ago VMware released the Orchestrator MP which is a superb way to directly call vRO workflows from vROps by way of alerts and actions.

When I deploy a new service into a namespace, I need to create a new DNS record that makes it available. I’ve previously talked about using CoreDNS to host my lab DNS zones, but this is something different. I want to make a Kubernetes Service available using an existing Microsoft DNS server - which is already used by all the clients who would need to access the service. To do this I will create a delegated zone under my existing zone cmbu.

To generate a basic authentication header from a username and password in Code Stream you could use a CI task and execute echo -n username:password | base64 in the shell then export the result for use later on. A more repeatable way is to create a Custom Integration that takes the two inputs, and returns the encoded header as an output.

As more services go live on my Kubernetes clusters and more people start relying on them, I get nervous. For the most part, I try and keep my applications and configurations stateless - relying on ConfigMaps for example to store application configuration. This means with a handful of YAML files in my Git repository I can restore everything to working order. Sometimes though, there’s no choice but to use a PersistentVolume to provide some data persistance where you can’t capture it in a config file.

If you’re anything like me, your home lab is constantly changing, evolving, breaking, rebuilding. For the last year or so I’ve been running all my home kubernetes workloads on a Raspberry Pi cluster - and it’s been working really well! I’ve been through several iterations - for example firstly running on SD cards (tl;dr - it’s bad, they wear out really fast with Kubernetes on board!), then PxE booting them from my Synology to it’s now current state of booting directly from SSDs.

In the most recent round of vExpert sub-program applications, I was asked to help review applications for the vExpert Cloud Management track. As part of the CMBU and a long-standing vExpert it made sense for me to help out, and I was happy to do so. I reviewed ~60 of the applications that were in my area - automation. The experience was an eye-opener. What follows is a distillation of what (not) to do when you’re writing your application.

vROps Cluster without a Load Balancer (gotchas) Product Version - vRealize Operations 7.5 While it is far from recomended to deploy a vROps Cluster without a loadbalancer there are circumstances where this is done. Recently helping a customer deploy a couple of simple issues cropped up that were not immediately obvious as to why they were issues. Unable to connect to Master Node when expanding the cluster We hit this issue and initialy it was a question mark moment there were no firewalls in the way and network connectivity was good end to end.
