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

———-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 day 1 stream recording. You can find my sessions at 54:23:

New ebook – Azure Arc enabled Kubernetes for Multicloud on O’Reilly

After 6 books with many authors from Packt, APress, & Sams/Pearson I finally had the chance to author a book with O’Reilly. This is an ebook so it can be found and read on the O’Reilly online platform.

It is a great platform that I use personally for my own learning. On their platform, you can find ebooks, books across many publishers (most of my books are on there), video training, and even live training.

This book brings together 4 exciting technologies/topics including Azure, Kubernetes, GitOps, and multi-cloud. The book is shorter than my typical books since it is an ebook. It is only 35 pages and is designed for fast & easy consumption to get an overview of the technology and get an early start.

In this book, we take a journey into one of Microsoft’s newest cloud services Azure Arc enabled Kubernetes (Arc K8s). We explore what Azure Arc K8s is, how it extends the Azure control plane to Kubernetes clusters to manage, secure, and govern them, as well as how GitOps sits are the core of application deployment to Kubernetes clusters and a driver of consistent configuration management for Kubernetes clusters.

Azure Arc is a Microsoft product that promises to extend the Azure control plane for Kubernetes across multiple clouds and on-premises, but how does it do this? In this ebook we will dissect Azure Arc K8s and how it becomes a secret weapon for managing Kubernetes clusters across on-premises, multiple clouds, and regardless of your own rolled Kubernetes clusters or managed services based Kubernetes clusters such as GKE, EKS, etc. I also want to give a shout-out to Michael Levan for reviewing this ebook!

Key Areas from the ebook include:

-Understand the new management challenges that multicloud brings
-Learn how Azure Arc drives consistent governance, security, and management across multicloud
-Gain valuable insights into Microsoft’s Azure ARM control plane for Kubernetes
-Learn how Azure Arc manages Kubernetes clusters across on-premises and multiple cloud deployments
-Explore the GitOps technology pattern and operating model for cloud native applications and Kubernetes
-Use Azure Arc-enabled Kubernetes and GitOps to deploy configurations and applications to Kubernetes clusters
