Using non-root SQL Server containers on Docker and K8s

By | Database Administration & Monitoring, DevOps, Docker, Kubernetes, SQL Server | No Comments

This is something that I waited for a while, in fact since SQL Server 2017 … and the news came out on Wednesday 09th September 2019. Running Non-Root SQL Server Containers is now possible either on the next version of SQL Server (2019) and it has been backported on SQL Server 2017 as well. Non-root SQL Server containers will likely be part of hidden gem of SQL Server new features, but this is definitely a…

How to get a big picture of K8s pods and PVs by script

By | Database Administration & Monitoring, DevOps, Docker, Kubernetes | No Comments

A couple of weeks ago, during an internal dbi services workshop about Docker and K8s, I got an interesting question: is it possible to get a big picture of pods connected to one specific persistent volume (PV) by using kubectl command? It was an interesting question because if we go through the usual kubectl command, it doesn’t provide natively the desired output. In fact, one one hand we get information about PVs and their related…

We enhance a lot our skills during the last months on the administration of Kubernetes cluster and…

Kubernetes – How to install a single master cluster with kubeadm?

By | Database Administration & Monitoring, DevOps, Docker, Kubernetes | No Comments

To bootstrap a minimal K8S cluster for testing purpose, kubeadm is a very interesting tool. The goal of this blog is not to explain to you the K8S architecture or the components but only the deployment part. using kubeadm. The final architecture of our cluster will be the following: Source:https://elastisys.com/2018/01/25/setting-highly-available-kubernetes-clusters/ Docker Installation The first step is to install Docker on each cluster node: yum install yum-utils device-mapper-persistent-data lvm2 yum-config-manager \ –add-repo \ https://download.docker.com/linux/centos/docker-ce.repo yum update…

Windocks and K8s support

By | DevOps, Docker, Kubernetes, SQL Server | No Comments

I got recently the 4.08 update from the Windocks team and I was very excited to evaluate some of new features. The first cool one I want to present in this blog concerns the Kubernetes support for deploying Windocks containers that will make my application deployment definitely easier. Let’s say you want to deploy your application that is tied to a Windocks container for SQL Server. In a previous blog post I explained why we…

Windocks, SQL Server and Azure in our internal CI pipeline

By | Cloud, DevOps, Docker, Kubernetes, SQL Server | One Comment

During the last DevOps Day in Geneva, I presented a sample of our CI implementation related to our MSSQL DMK maintenance product. It was definitely a very good experience for me and good opportunity to get feedback from DevOps community as well. During the session I explained our CI pipeline includes SQL Server containers both on AKS (K8s as managed service in Azure) and Windocks. I got questions from some of attendees who asked me…

Upgrading SQL Server pods on K8s and helm charts

By | Database Administration & Monitoring, DevOps, Docker, Kubernetes, SQL Server | No Comments

It has been while since my last blog. Today it is about continuing with helm charts and how to upgrade / downgrade SQL Server containers to a specific cumulative update. My first write-up in my to-do list. Last year, I wrote an introduction of SQL Server containers on K8s. I remembered to face some issues when testing upgrade scenarios (probably a lack of knowledge). Since then, I have discovered helm charts and I use them…

Deploying SQL Server 2019 AGs on K8s with helm charts

By | Database Administration & Monitoring, DevOps, Docker, Kubernetes, SQL Server | No Comments

This write-up follows my first article about helm chart with SQL Server. This time, I would like to cover the availability groups topic and how to deploy them with helm charts. In fact, to go through this feature for AGs was motivated to its usage in our Azure DevOps CI pipeline in order to deploy a configurable one on an AKS cluster with SQL Server 2019. If you look carefully at the release pipeline, Windocks…

Deploying SQL Server on K8s with Helm charts

By | Database Administration & Monitoring, DevOps, Docker, Kubernetes | No Comments

During the last DockerCon EU in Barcelona, I heard a lot about Helm with K8s architectures. It was also a good opportunity to write about it after attending to this conference. In a nutshell, Helm is a package manager for K8s and you may think of it like the other ones available on the Linux side with apt, yum or zypper to cite few of them. Helm charts are a key component of the Helm architecture and…
