A Fine Slice Of SQL Server
Do we really want to be typing all that out every time we run a container? Ok, we could drop this into a script and execute that but another option is to use environment variable files.
Nice and simple, we take all the environment variables in the statement above and drop them into a file on our Docker host: –
Read on and gauge for yourself how nice and simple it is.
Comments closedAnthony Nocentino wants to set some permissions:
This post will walk you through setting file permissions on database files copied into a container. The SQL Server process
sqlservrrunning in containers runs as the non-privileged usermssql. The appropriate permissions on files are needed, so the SQL Server process has the proper access to any database files, log files, and backup files.
Click through for the process.
Comments closedI’ve heard about Dapr a few times from developer friends, but hadn’t really understood it that well. I had a webinar coming up, so I decided to spend a bit of time working with it to understand how it might function with an application.
I went to https://dapr.io/, and saw the basic outline of Dapr is in this video from their site. I also found this getting started video from Donovan Brown.
Note that Dapr is totally different from Dapper.
Comments closedGrant Fritchey has an editorial:
I find myself doing more and more work with containers. Yet, I also find that a lot of people seem to be resistant to the concept. I’m always surprised when technologists reject technology without fully understanding what it does. Let’s talk about this just a little.
I completely agree with Grant’s assessment and want to pile on a bit about cloud services and containers. If you’re using or thinking of using services like Azure Machine Learning or Azure IoT Hub, that work is all containerized. And there’s a lot which runs in containers that we don’t even think about. You don’t need to live your life in containers or run everything from containers, but they’re useful in several contexts.
Comments closedAmit Khandelwal has a walkthrough for us:
In this blog today, let’s configure AD (Active Directory) authentication for SQL Server containers running on Azure Kubernetes Service (AKS). Same steps can be followed for SQL Server containers deployed on other kubernetes environments as well.

Comments closedIonut Ilascu reports on a vulnerability:
Microsoft has fixed a vulnerability in Azure Container Instances called Azurescape that allowed a malicious container to take over containers belonging to other customers on the platform.
An adversary exploiting Azurescape could execute commands in the other users’ containers and gain access to all their data deployed to the platform, the researchers say.
This is fixed now, but it’s a good reminder that platform-as-a-service offerings can still have security problems (as we’ve also seen recently with Power Apps and Cosmos DB).
Comments closedAndrew Pruski doesn’t have time to restart containers:
When running multiple SQL Server containers on a Docker host we should always be setting CPU and Memory limits for each container (see the flags for memory and cpus here). This helps prevent the whole noisy neighbour situation, where one container takes all the host’s resources and staves the other containers.
But what if we forget to set those limits? Well, no worries…we can update them on the fly!
Click through to see how you can change the memory limits on a running container.
Comments closedTsuyoshi Matsuzaki shows us how to deploy an Azure ML model via custom Docker image:
In my early post, I have showed you how to bring your own custom docker image in training with Azure Machine Learning.
On the contrary, here I’ll show you how to bring custom docker image in model deployment.In Azure Machine Learning, the base docker image in deployment includes the inferencing assets, such as, Flask server, etc. So you should use AML compliant image for base image, even when you use your own custom docker image.
The list of these maintained AML images is available in https://github.com/Azure/AzureML-Containers .
Read on for an example.
Comments closedJoy George Kunjikkur takes another stab at Kubernetes:
This is 3rd or 4th time, I am learning Kubernetes (hereafter mostly refer as K8s short form) hands-on sessions. Every time I learn the kubectl command and its options, I forget as there were no chances to apply in the day job. Another mistake I did all those times was missing to post learning to this blog.
Hope this time I will get a chance to use it in the day job and not miss posting the Kubernetes learning on to this blog.
This post is very basic. The aim is to get started with the Kubernetes development environment using Docker Desktop. Below are the steps at a high level to get started. Detailed steps with videos are available on the internet.
Read on for some installation tips, including how to install the Kubernetes dashboard for a UI experience.
Comments closedShivam Gupta explains four key strategies for pushing out deployments:
K8s Deployment has different types of strategies to update the deployment. Each has difference in the way to how the achieve the new desired state.
– Rolling Update
– Recreate
– Canary
– Blue/Green
Read on for a quick summary of each strategy, as well as its pros and cons.
