Persistent Server Name Metadata When Deploying SQL Server in Kubernetes

In this post, we will explore how a Pod name is generated, Pod Name lifecycle, how it’s used inside a Pod to set the system hostname, and how the system hostname is used by SQL Server to set its server name metadata.

Pod Naming in Deployments

When deploying SQL Server in Kubernetes using a Deployment, the Pod created by the Deployment Controller will have a name with a structure of <DeploymentName>-<PodTemplateHash>-<PodID> for example, mssql-deployment-8cbdc8ddd-9n7jh.

Speaking at SQLBits 2020

I’m proud to announce that I will be speaking at SQLBits! I had the absolute pleasure of speaking at SQLBits last year for the first time and saw first hand how great this event is and cannot wait to get back and speak again! And this year, I have two sessions!!! One on building and deploying container based applications in Kubernetes and the other on deploying SQL Server in Kubernetes

If you haven’t been to SQLBits before, what are you waiting for! Sign up now!

Speaking at SQLIntersection Orlando 2020

I’m very pleased to announce that I will be speaking at SQL Intersection April 2020!  This is my first time speaking at SQL Intersection and I’m very excited to be doing so!

<p>
  Speaking at SQL Intersection means so much to me because in 2014 I got my first exposure to the SQL Server community via <a href="https://www.sqlskills.com/">SQLskills</a> and their training. Then to follow up on their training workshops I attended my very first IT conference, SQL Intersection and now I get to come back as a speaker. Let’s just say, I’m a little excited!!!
</p>

<p>

  <p>
    Modern application deployment needs to be fast and consistent to keep up with business objectives and Kubernetes is quickly becoming the standard for deploying container-based applications, fast. In this day-long session, we will start with an architectural overview of a Kubernetes cluster and how it manages application state. Then we will learn how to build a production-ready cluster. With our cluster up and running, will learn how to interact with our cluster, common administrative tasks, then wrap up with how to deploy applications and SQL Server. At the end of the session, you will know how to set up a Kubernetes cluster, manage a cluster, deploy applications and databases, and how to keep everything up and running.

</p>

<blockquote>
  <p>
    Do you manage SQL Server but have developers using Linux? It’s time to take the leap to understand and communicate better with your Linux peers! You might be a Windows / SQL Server Admin but both SQL Server and PowerShell are now available on Linux. You can manage ALL of these technologies more effectively now. Don&#8217;t fear! Linux is just an operating system! While it feels different, it still has all the same components as Windows! In this session, I’ll show you that. We will look at the Linux operating system architecture and show you how to interact with and manage a Linux system. By the end of this session, you&#8217;ll be ready to go back to the office and get started working with Linux with a fundamental understanding of how it works.

</p>

<blockquote>
  <p>
    Taking what you learned in our Fundamentals session one step further, we will continue and focus on the performance data you’re used to collecting on Windows! We&#8217;ll dive into SQLPAL and how the Linux architecture / internals enable high performance for your SQL Server. By the end of this session you’ll be ready to go back to the office and have a solid understanding of performance monitoring Linux systems and SQL on Linux. We’ll look at the core system components of CPU, Disk, Memory, and Networking monitoring techniques for each and look some of the new tools available from DMVs to DBFS.
  </p>
  
  <p>
    In this session we’ll cover the following
