So, if you’ve been following my blog you know my love for internals. Well, I needed to find out exactly how something worked at the startup of a SQL Server process running inside a docker container and my primary tool for this is strace, well how do you run strace against processes running in a container? I hadn’t done this before and needed to figure this out…so let’s go through how I pulled this off.
A quick post about pulling docker containers (this applies to docker run too)…when specifying the container image, the container image name and tag are case sensitive. We’re not going to discuss how much time troubleshooting it too me to figure this out…but let’s just say it’s more than I care to admit publicly. In this code you can see I’m specifying the following image and tag server:2019-rc1-ubuntu (notice the lowercase rc in the tag)
In the first two posts in this series we discussed the need for data persistency in containers then we discussed where the data actually lives on our systems. Now let’s look at specifying the location of the data on the underlying file system of the base OS. This is the third post in a three part series on Persisting SQL Server Data in Docker Containers. The first post introducing Docker Volumes is here.
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.
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.

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 vision for PowerShell Core is to be able to run PowerShell anywhere. In this article, I’m going to discuss how you can use Docker Containers to enable just that. We’ll look at running PowerShell in a container, running cmdlets, running different versions of PowerShell at the same time, and also how to build our own “serverless” computing platform. Let’s address a few reasons why you would want to run PowerShell in a container.
