Recently I needed to take a look at all of the SQL Server Agent Jobs and their Jobs Steps for a customer. Specifically, I needed to review all of the Jobs and Job Steps for Ola Hallengren’s Maintenance Solution and look at the Backup, Index Maintenance and Integrity Jobs to ensure they’re configured properly and also account for any customizations and one-offs in the Job definitions. This customer has dozens of SQL Server instances and well, I wasn’t about to click through everything in SSMS…and writing this in TSQL would have been a good candidate for a Ph.
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.
I’m pleased to announce that I will be presenting at PASS Summit. This year I have a pre-conference workshop and a regular session. Let’s dive into each. Pre-Conference Workshop: The Future of Deployment for Modern Data Platform Applications Ben Weissman and I teach a pre-conference workshop called “The Future of Deployment for Modern Data Platform Applications” in this workshop. We’re going to cover how you will be deploying data platform applications in the near future.
I’m proud to announce that I will be speaking at Data Grillen 2020 the conference runs from 28 May 2020 through 29 May 2020. This is an incredible event packed with fantastic content, speakers, bratwurst and Beer! **Check out the amazing schedule (**and when I say check out the amazing schedule, I really mean it. Some of the world’s best Data Platform speakers are going to be there) On Thursday**, May 28th at 15:00** – I’m presenting “**Containers – Day 2**” in the **Handschuh room**.
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 <p> If you haven’t been to SQLBits before, what are you waiting for!
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.
Yesterday in this post I described a method to correct permissions when upgrading a SQL Server 2017 container using Data Volumes to 2019’s non-root container on implementations that use the Moby or HyperKit VM. My friend Steve Jones’ on Twitter wondered if you could do this in one step by attaching a shell (bash) in the 2017 container prior to shutdown. Absolutely…let’s walk through that here in this post. I opted to use an intermediate container in the prior post out of an abundance of caution so that I was not changing permissions on the SQL Server instance directory and all of the data files while they were in use.
Recently Microsoft released a Non-Root SQL Server 2019 container and that’s the default if you’re pulling a new container image. But what if you’re using a 2017 container running as root and want to upgrade your system the SQL Server 2019 container…well something’s going to break. As you can see here, my friend Grant Fritchey came across this issue recently and asked for some help on Twitter’s #sqlhelp. This article describe a solution to getting things sorted and running again.
I’m very pleased to announce that I will be speaking at PASS Summit 2019! This is my second time speaking at PASS Summit and I’m very excited to be doing so! What’s more, is I get to help blaze new ground with an emerging technology,** Kubernetes and how to run SQL Server in Kubernetes**! My session is “Inside Kubernetes – An Architectural Deep Dive” if you’re a just getting started in the container space and want to learn how Kubernetes works and dive into how to deploy SQL Server in Kubernetes this is the session for you.
People often ask me what’s the number one thing to look out for when running SQL Server on Kubernetes…the answer is memory settings. In this post, we’re going to dig into why you need to configure resource limits in your SQL Server’s Pod Spec when running SQL Server workloads in Kubernetes. I’m running these demos in Azure Kubernetes Service (AKS), but these concepts apply to any SQL Server environment running in Kubernetes.
