A day at DevOps World in Lisbon

This was also the opportunity for us (Arnaud and I) to meet our main customer from whom we are working with Jenkins X each day. It is always interesting to be able to meet physically the people with whom we collaborate, even if…

Provisioning a AKS cluster and KubeInvaders with Terraform

By | Cloud, DevOps, Kubernetes | No Comments

Provisioning a K8s infrastructure may be performed in different ways. Terraform has a connector called the Kubernetes provider but it doesn’t allow building and deploying a Kubernetes cluster. The cluster must be up and running before using the provider. Fortunately, there are different cloud-specific provider depending which cloud provider you want to provision your cluster. In our CI pipeline for the MSSQL DMK maintenance, we provision SQL Server containers on Linux to perform then different…

Kubernetes DNS resolution using CoreDNS (force update deployment)

By | DevOps, Docker, Kubernetes | No Comments

After installing your Kubernetes cluster composed by masters and workers, a few configurations steps need to complete. In fact, the join command is not the last operation to perform, in order to have a fully operational cluster. See how to deploy a k8s cluster using kubeadm here: https://blog.dbi-services.com/kubernetes-how-to-install-a-single-master-cluster-with-kubeadm/ . One of the most important steps in the configuration is the name resolution (DNS) within the k8s cluster. In this blog post, we will see how…

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…

Deploying SQL Server 2019 container on RHEL 8 with podman

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 | 2 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…

Deploying SQL Server on Azure virtual machine with Terraform

By | Cloud, DevOps, SQL Server | 4 Comments

We are entering now to the infrastructure as code world and provisioning a SQL Server infrastructure is not excluded from the equation. This is especially true when it comes the Cloud regardless we are using IaaS or PaaS. One great tool to use in such scenario is certainly terraform and I introduced it during the last PowerSaturday pre-conference named “DBA modern competencies”. Installation paradigms in the cloud differ from what we usually do on-premises either…
