SQL Server

So in my previous post, we discussed Docker Volumes and how they have a lifecycle independent of the container enabling us to service the container image independent of the data inside the container. Now let’s dig into Volumes a little bit more and learn where Docker actually stores that data on the underlying operating system.

This is the second post in a three part series on Persisting SQL Server Data in Docker Containers. The first post introducing Docker Volumes is here. And the third post on mapping base OS directories directly into containers is here.

What’s the number one thing a data professional wants to do with their data…keep it around. Let’s talk about running SQL Server in Containers using Docker Volumes on a Mac

This is the first post in a three part series on Persisting SQL Server Data in Docker Containers. The second post on where Docker actually stores your data is here. And the third post on mapping base OS directories directly into containers is here.

Today, I’m proud to announce that I have been renewed as an Microsoft MVP – Data Platform for the 2019-2020 award year, my third MVP award. This is an truly an honor and I’m humbled to be included in this group of exceptional data professionals. I really look forward to continuing to work with everyone in the MVP community and continuing to contribute to our unmatched Data Platform Community!

  Here’s the abstract for the talk

<blockquote>

    You’ve heard the buzz about containers and Kubernetes, now let’s start your journey towards rapidly deploying and scaling your container-based applications in Azure. In this session, we will introduce containers and the container orchestrator Kubernetes. Then we’ll dive into how to build a container image, push it into our Azure Container Registry and deploy it our Azure Kubernetes Services cluster. Once deployed, we’ll learn how to keep our applications available and how to scale them using Kubernetes.

    Key topics introduced<br />Building Container based applications<br />Publishing containers to Azure Container Registry<br />Deploying Azure Kubernetes Services Clusters<br />Scaling our container-based applications in Azure Kubernetes Services

Pre-conference Workshop at SQLSaturday Baton Rouge

I’m proud to announce that I will be be presenting an all day pre-conference workshop at SQL Saturday Baton Rouge on August 16th 2019! This one won’t let you down!

The workshop is **“Kubernetes Zero to Hero – Installation, Configuration, and Application Deployment” **

    <a href="https://www.eventbrite.com/e/kubernetes-zero-to-hero-by-anthony-nocentino-tickets-61845012096"><img loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" title="NewImage.png" src="/images/2019/01/Availability-Group-StatusNewImage-1.png" alt="NewImage" width="129" height="126" border="0" /></a>

    **Here’s the abstract for the workshop**

  <blockquote>

      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, we 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.

  Here’s the abstract for the talk

<blockquote>

    Containers are taking over, changing the way systems are developed and deployed…and that’s NOT hyperbole. Just imagine if you could deploy SQL Server or even your whole application stack in just minutes. You can do that, leveraging containers! In this session, we’ll get you started on your container journey learning container fundamentals in Docker, then look at some common container scenarios and introduce deployment automation with Kubernetes.

    In this session we’ll look at<br />Container Fundamentals with Docker<br />Common Container Scenarios<br />Automation with Kubernetes

    Prerequisites: Operating system concepts such as command line use and basic networking skills.

When working with SQL Server in containers and Kubernetes storage is a key concept. In this post, we’re going to walk through how to deploy SQL Server in Kubernetes with Persistent Volumes for the system and user databases.

One of the key principals of Kubernetes is the ephemerality of Pods. No Pod is every redeployed, a completely new Pod is created. If a Pod dies, for whatever reason, a new Pod is created in its place there is no continuity in the state of that Pod. The newly created Pod will go back to the initial state of the container image defined in the Pod’s spec. This is very valuable for stateless workloads, not so much for stateful workloads like SQL Server.

In this blog post, I’m going to show you how to use VS Code and Azure Data Studio for presentations where you need to execute local code on remote systems over SSH.

The Challenge

When using tools like VS Code and PowerShell ISE these tools give you the ability to highlight code and execute that highlighted code. This generally means the highlighted code you want to execute will execute against the local machine. When presenting, this technique is very useful and impactful for your audience because both the code being executed and its output will be on the screen at the same time as you step through your demos. I do a lot of presenting on topics like Linux, SQL Server on Linux, Kubernetes, and OpenSSH when I’m logged into remote hosts over SSH. I’d like to have the same functionality, so I can highlight the code in VS Code locally and execute that code on a remote host over SSH. Let’s explore how I do that.

In Kubernetes we can leverage Controllers to help manage our application state, keeping them in the desired state. In this blog post, we’re going to look at how to use a Deployment Controller to manage the application state of SQL Server in Kubernetes. We’ll look at deploying SQL Server in a Deployment and using that deployment to upgrade SQL Server and rollback our upgrade.

Deploying SQL Server in a Deployment

Let’s start off with deploying SQL Server in Kubernetes. We can do that with the following YAML file to describe our Deployment.
