Recently I was a guest on The Women in Linux Youtube channel. It was great to reconnect with Tameika Reed, Dionne Parler, and their team! Here is their website: www.womeninlinux.org. It has been many years since I was on their podcast. They have a weekly show named “How we Linux”. I highly recommend you check it out. I was on episode #14. We talked about many things from authoring tech books, the job market in tech, being a Microsoft MVP, the future of tech and even stocks! Check it out here:
Set Idle timeout and TCP Reset on Azure Load Balancer via a Service in AKS
Short post here. On a recent project, we had been deploying a workload on AKS that included a load balancer service type. This app has some long-running processes and we needed to stop the Azure load balancer from timing out so fast.
In order to better handle the long-running processes, I needed to enable the TCP reset and change the idle timeout (minutes) in the load balancing rule on the Azure Load Balancer. This is shown in the following screenshot:
So you can configure these settings by adding annotations to your Kubernetes manifest file. The full list of load balancer annotations can be found here: https://kubernetes-sigs.github.io/cloud-provider-azure/topics/loadbalancer/#loadbalancer-annotations The ones I needed specifically are:
annotations:
service.beta.kubernetes.io/azure-load-balancer-disable-tcp-reset: “true“
service.beta.kubernetes.io/azure-load-balancer-tcp-idle-timeout: “30“
This was great however it was not clear if the TCP Reset annotation was deprecated or not (see the following screenshot).
I tried it anyway and it worked. It looks like it will be removed at some point. This meets the need for now but is something to keep an eye on.
Speaking at the Jamaica Azure User Group on Intro to GitOps and AKS
On September 30th I will be speaking at the Jamaica Azure User Group giving an intro to GitOps and AKS!
Here is a breakdown of what I will be covering in this session:
CI/CD with Kubernetes on top of management of Kubernetes configuration management can be complex and intimidating. Application definitions, configurations, management, and continuous delivery for Kubernetes can be simplified, automated, and declarative. This can be achieved via GitOps.
Microsoft simplifies running Kubernetes with Azure Kubernetes Service (AKS) but it can still be complex when it comes to the management you are responsible for and application deployment.
In this session we will take a look at:
-An intro into AKS
-An intro into GitOps
-How you can utilize GitOps and git-based techniques with AKS to drive easier application deployment
-How to use GitOps for configuration management of Kubernetes from your source control system

Here is my session info:
GitOps and Kubernetes: a Winning Combo
GitOps is an emerging pattern for cloud-native applications. This operating model simplifies Kubernetes ops while simultaneously improving the developer experience. GitOps enables continuous delivery of configuration updates and application deployments to Kubernetes.
Through the lens of GitHub, Argo CD, and Azure Kubernetes Service, we’ll explore use cases and benefits, principles and practices, architecture and tooling, and what GitOps changes in our day-to-day.
Check out the full program for the event here: https://devopsdays.org/events/2021-minneapolis/program
For those that won’t be attending in person you can Live stream it on YouTube here:

———-Update 7/21/21———-
Today I delivered my session on GitOps and Kubernetes: a Winning Combo. This was my first in-person event since the pandemic in the US started. I went on stage right after Ian Coldwater gave the keynote. Ian had an amazing keynote talking about community, how the pandemic and the murder of George Floyd impacted Minneapolis last year along with how the community came together. I presented to a crowd of a few hundred as well as another couple hundred online.
The online reach of this event was amazing. I even received a message that my session was watched by some folks in Japan!
In my session, we went on a journey through how companies should focus on being software businesses moving to digital, how the pandemic accelerated companies and consumers going digital as well as companies using Kubernetes and GitOps as a way to help power digital transformation.
The conference organizers did a great job pulling off another excellent event while ensuring everyone followed safety guidelines.
Here is the stream recording of my session:

10th Year as a Microsoft MVP!
Happy to be a Microsoft MVP for the 10th year even though this is not like the other years. As always I never take this award for granted. It is not guaranteed. Every year when July 1 rolls around I never truly know if I will be back in the MVP program or not.
This is my third year as an Azure focused MVP. Again I am honored to be among the ranks of taltented Azure folks. I am looking forward to the 2021-2022 MVP award year full of exciting community stuff. I plan to do more speaking, podcasts, books, and of course Pluralsight courses. I also plan to pick up blogging again and getting a little more active posting blogs on here.
As always I am honored to remain a part of MVP program. I will continue to do all that I can in the Azure, Azure Arc, AKS, and GitOps/DevOps communities this year.
