Ansible Container: Chronicle of a Death Foretold

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…

JenkinsX – new Kubernetes dream? Part 1

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…

The upstream Kubernetes

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…

The Twelve-Factors Kubernetes

“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…

Edge Computing : learn to delegate

While the interest for the Internet of Things by companies is no longer to be proven, this area continues to give a hard time to experts, as for security and architecture. Indeed, the multiplication of data sources brings a reflection on the architecture of networks. As Satya Nadella (Microsoft CEO) said on stage in 2017: "When I joined Microsoft in 1992, all Internet traffic was 100 gigabytes a day. Today is 17.5 million times that amount ... per second! "And we are only at the…
