During a recent training, a student asked me how I would update the configuration of CoreDNS on a Kubernetes cluster, when the cluster is deployed is Terraform and comes with CoreDNS pre-installed.

Je ne sais pas exactement combien de talks j’ai donné dans ma carrière (probablement quelques centaines).

Durant ma carrière, j’ai participé à des centaines de conférences en tant qu’intervenant, et j’ai été plusieurs dizaines de fois organisateur ou membre du comité de sélection.

I recently went down a very deep rabbit hole to understand why, some months, Cloudflare was charging us 3x what we were expecting for their Cloudflare Images service.

I recently investigated a warning message on Kubernetes that said: DNSConfigForming ...

Six months ago, I started using Wayland (the graphics stack that will replace X11 on Linux).

Once in a while, I need to install Archlinux on a new machine.

This is a story of how we identified a performance issue in EphemeraSearch.

To all my LGBT+ friends, peers, and fellow members of the Kubernetes and Cloud Native communities: you do belong here.

This is a list of recurring anti-patterns that I see when I help folks with their container build pipelines, and suggestions to avoid them or refactor them into something better.

Je suis abonné à une newsletter qui synthétise l’information quotidienne.

I recently decided to check how much it would cost to offset the carbon footprint of my air travel.

env0 is a SaaS that can deploy Terraform plans, track their cost, and automatically shut them down after a given time.

If you are using Linux as your main operating system, you might wonder if it’s doable to use it to stream content, and how.

In this article, I’ll talk about the various services and tools that I tried to stream my presentations.

This is a long description of the various equipment (cameras, lights, mics, and more) that I am using, or that I have tried to use, to deliver online training and tech talks.

In March 2020, I started delivering online training sessions (instead of doing it in person).

In the beginning of this series (first part, second part), we covered the most common methods to optimize Docker image size.

In the first part, we introduced multi-stage builds, static and dynamic linking, and briefly mentioned Alpine.

When getting started with containers, it’s pretty easy to be shocked by the size of the images that we build.

There is a lot of material out there about services meshes, and this is another one.

I’ve just published a series of video of a one-day Kubernetes tutorial that I recently delivered in London.

Capacity planning with Kubernetes is a non-trivial challenge.

For anyone using containers, Docker is a wonderful development platform, and Kubernetes is an equally wonderful production platform.

Cette article est la suite du précédent.

Dans le monde des conteneurs, Docker est une formidable plateforme de développement, et Kubernetes une tout aussi formidable plateforme de production.

I’m going to try to explain how I felt when I was struggling with depression.

What’s the difference between a junior and a senior software engineer?

On parle souvent des conteneurs comme un moyen d’accélérer les cycles de développement, mais ils permettent aussi de dérisquer (ou réduire les risques, si le néologisme vous fait grincer des dents ☺) les opérations de déploiement.

Depuis quelques années, l’industrie du logiciel parle énormément des containers ; notamment de deux projets phares de cet écosystème : Docker et Kubernetes.

I was given the opportunity to test AppSwitch, a network stack for containers and hybrid setups that promises to be super easy to deploy and configure, while offering outstanding performance.

This is a boring post about boring tax stuff.

TL,DR: I have left Docker Inc. to take a sabbatical and recover from depression and burnout.

I want to share a few organizational tools that helped me to be more productive while dealing with stress, anxiety, and depression.

A few months ago, I started using a 2017 12” Macbook Air.

A few months ago, I wrote and delivered a Kubernetes orchestration workshop, based on my Swarm orchestration workshop.

Just because we’re using containers doesn’t mean that we “do DevOps.”

You’ve accepted to be a “track host,” but you don’t know how to do it?

I’d like to tell you a short story illustrating why training your employees is crucial to the success of your organization.

Have you heard about dotCloud?

If you are running apps in containers and are using Docker’s GELF logging driver (or are considering using it), the following musings might be relevant to your interests.

In conversations about sexism (in the tech industry or elsewhere), men are often surprised to hear how bad the situation is for some of their women coworkers and friends.

I usually write in English, about container technology.

This is a short collection of tips and tricks showing how Docker can be useful when working with Go code.

A while ago, I wrote about how to bind-mount the Docker control socket instead of running Docker-in-Docker.

TL,DR: we all have different perceptions and experiences.

Here are a few tips and tricks that I learned when building then delivering the Docker Fundamentals course at Docker Inc.

The primary purpose of Docker-in-Docker was to help with the development of Docker itself.

This number is wonderful.

In a Dockerfile, if you put data in a directory, and then declare that directory to be a volume, weird things can happen.
