Infrastructure and Operations

Dans le cadre d’un environnement de “delivery” agile, il est important d’être réactif sur les cycles de vie des applicatifs ainsi que sur leur initialisation. L’offre des outils permettant de gérer l’intégration et le déploiement continu est de plus en plus fournie (il serait quasi-impossible de tout recenser !), les DSI des grands groupes (principalement), tentent d’abstraire cette complexité en rendant la création des pipelines CI/CD le plus générique possible. On cherche alors à mutualiser le plus possible, afin d’accélérer au démarrage et faciliter la…

Tl;dr In my experience, software developers’ skills regarding tasks in a terminal range from desperately slow to impressively swift. I believe that, for a large part, this is caused by an abundance of articles not discussing the real problems software developers are dealing with daily. Namely, how to feel productive on a terminal, after using omnipotent integrated software environments for so long. This article aims at bridging this gap by sharing carefully selected tips that can, in my opinion, dramatically increase the terminal productivity of…

Let’s talk about communication for a bit. One of the most interesting roles I’ve had to fulfil the last couple of years has been the “Operations guy working as a part of a Development team”. This is a fascinating situation to find yourself in. Allow me to elaborate. Historically, Operations teams have been isolated from Development teams. Two separate organizational entities. The reasons for this were manyfold: Operations people were a scarce resource, they needed to accommodate vast amounts of work for numerous Development teams…

Alright, story time fellas. TL;DR; We’re working with Terraform, layering and workspaces. This makes the standard `terraform workspace select x` pretty cumbersome and dangerous. We wrote a Ruby wrapper using Test-Driven Development. It allows us to have a tested, maintainable and efficient solution to the aforementioned issue. You can find the actual project here: https://github.com/sebiwi/terraform-wrapper If you keep reading, we’re going to talk about scripting, Test-Driven Development, Terraform and Ruby.

Alright, here’s what’s up: TL;DR We tried Ansible Container. We’d rather keep using Dockerfiles for image builds: creating a Docker image and provisioning servers with Ansible are two very different things. Different in terms of lifecycle, philosophy and workflow. So different, that in our opinion, they’re not compatible. Wanna know why? Read on. Disclaimer: While the current status of Ansible Container is not clear, it seems that during the writing of this article the tool has been deprecated: https://github.com/ansible/ansible-container/commit/2fa778a7c8d1699672314ac0b89c53554f435cb7. After the limitations we noticed, we…

Alright, stranger! As we pass through the stage of basic Jenkins X overview in our  first part , we are ready to go to infinity and go beyond the general application of Kubernetes environment. In this article, we are going to step further into Jenkins X world, by going through a step-by-step setup process and creating quickstart project. Furthermore, you will get an overview of what is going on in the background, detailed description of Git flow, release management and magic behind deployment automation. Please,…

Hi there! Today we’re going to share about Jenkins X. I think every developer knows what Jenkins is. Or at least has heard of it once. But what is ‘X’? Basically, Jenkins X is not just a CI/CD tool to run your builds and deployments, it is an attempt to automate the whole development process end to end for containerised applications based on Docker and Kubernetes. It is obviously open source, as all best applications. This sounds very promising at a high level. So, let’s…

Kubernetes has quickly become the de facto standard for container orchestration. If the basics are now well understood, the new “upstream” features are much less, even though they make the product richer and able to address some very specific use cases. This article is a review of these new features, as well as the upcoming ones that come with the 1.10 release. A prior knowledge of kubernetes is a prerequisite. Disclaimer: some of these features are alpha, meaning that some backward incompatible changes may be…

See the previous episode here. He has questions. Nevertheless, he has not yet arrived. And you know you have answers. You interrupt your summoning, and sit down. You can continue in another moment. Everything happens for a reason. You just hope the reason is good. N appears right next to you. Hey, what’s up? I'm setting up the auto-scaling configuration of the new project. Nothing huge. Cool. I need some help. He has progressed immensely since the last time you saw him. People are starting to…

“Kubernetes is the Linux of the cloud”This quote by Kelsey Hightower during the Kubecon 2017 in Austin emphasize the rise of Kubernetes among modern cloud infrastructures. This rise is partly driven by the developers community, but also by the web giants such as Google, Amazon, Alibaba or Red Hat who have invested a lot on this technology, and keep contributing to its improvement and smoothening its integration to their respective ecosystems. EKS for AWS, GKE for Google and AKS for Azure are good illustrations of…
