It’s hard to believe that my first VMworld was almost 9 years ago! I feel very blessed to have attended in 2014 (EU), 2015 (EU), 2016 (US), 2017 (EU), 2018 (my first as an employee), 2019 (my first time as a speaker!), and virtually in 2020 and 2021.
Over the years VMworld has been hugely formative in my career, I’ve talked many times before about how the trajectory of my career really took off when I got involved with the London VMUG, and how that led to being awarded vExpert in 2013.
In my previous post I walked through configuring kubernetes ingress with automatically generated SSL certificates and DNS registration using Tanzu Kubernetes Grid’s Packages. Another of the packaged applications available is Fluent-bit, which enables log forwarding from your Kubernetes cluster and workloads to a range of supported logging endpoints.
There are a couple of tweaks required in order to forward logs to vRealize Automation Log Insight Cloud. We need to use the HTTP output in the Fluent Bit configuration to forward the logs as a JSON payload to the Log Insight API.
Just recently Docker announced some new pricing tiers for it’s almost ubiquitous Docker Desktop. I’m not going to opine much on this, time will tell whether this is a company saving move or not. Suffice to say that I work for a large company and would need a subscription to continue using Docker Desktop.
The venerable Corey Quinn was on the news like a flash, so I’ll let you read his thread for some hard core snark analysis.
I can tell from the ever-increasing urgency of emails from the events team that VMworld 2021 is just around the corner!
Virtual conference event fatigue is real. I have attended and presented at many since the pandemic began, with varying levels of engagement. As an introvert, I can’t quite believe I’m saying this, but I can’t wait to get pack to meeting up with people in the real world!
The value of a conference is super-charged by the mix of dedicated time, networking opportunities and quality live content.Written by Sam McGeown

I was doing some testing with adding an external vRealize Orchestrator 8.4 endpoint to vRealize Automation Code Stream 8.4, and it turns out there’s a redirect that happens with the vRO 8.4 appliance that makes the endpoint validation fail. When you enter the URL and click ACCEPT CERTIFICATE the UI will throw an error: Server error on getting certificates.
Http failure response for https://<vRA FQDN>/codestream/api/endpoint-certificate?url=https://<vRO FQDN>: 400 Bad Request
Error getting certificates!
Most of my home network runs on my Raspberry Pi Kubernetes cluster, and for the most part it’s rock solid. However, applications being applications, sometimes they become less responsive than they should (or for example, when my Synology updates itself and reboots, any mounted NFS volumes can cause the running pods to degrade in performance). This isn’t an issue with service liveliness, which can be mitigated with a liveness probe that restarts the pod if a service isn’t running.
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.Written by Sam McGeown
