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…

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

Having a fresh install of RHEL8 on my lab environment, I was curious to take a look at new containerization stuff from Red Hat in the context of SQL Server 2019. Good chances are the future version of SQL Server should be available and supported on with the latest version of Red Hat but for now this blog post is purely experimental. This time I wanted to share with you some thoughts about the new…

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…

SQL Server containers and docker network driver performance considerations

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

Few months ago I attended to the Franck Pachot session about Microservices and databases at SOUG Romandie in Lausanne on 2019 May 21th. He covered some performance challenges that can be introduced by Microservices architecture design and especially when database components come into the game with chatty applications. One year ago, I was in a situation where a customer installed some SQL Server Linux 2017 containers in a Docker infrastructure with user applications located outside…
