I’m managing applications inside Kubernetes for more than 2 years for MySocialApp a social news feed solution and recently Referlab, an impressive referral marketing solution. If you follow me, you certainly know that I’ve made multiple Helm charts on distributed technologies like: Cassandra Helm chart Elasticsearch Helm chart Traefik Helm chart After several years of experience on it, you can trust me when I say managing statefulset on Kubernetes is not the easiest thing to do.

Since several years, I’m hosting a lot of things: blog, wiki, emails etc… I’ve played with Vserver, OpenVZ, KVM and finaly LXC. For years, I’ve learned how to use all of them but the most known solution during the last years is Docker. I even can remeber the first Meetup I’ve attended in Paris talking about Docker 5 years ago. Now containers are eveverywhere. I recently changed the server I’m running for my own usage and this was the good timing to switch from LXC to Docker.

WireGuard is a very good alternative to OpenVPN. I’ve been using OpenVPN for more than 10 years now and I was happy until I understood how slow it can be on low energy devices like EdgeRouter. To give you an idea, on my Fiber Home connection (200Mbps), I’m limited to 18Mbps. With OpenVPN, I’m reaching the maximum CPU usage on the EdgeRouter. I’ve heard of WireGuard about a year now and it was time for me to test this interresting alternative.

I’ve a Ubiquiti EdgeRouter PoE since several years now and really like it. Fanless, small, running on Debian (unfortunately not really up to date) and powerful. However I recently had issues with the disk. Simply dead and obviously a reboot didn’t repaired it. I’ve been searching solutions on the official forum to replace the disk and I was surprised about the fact it runs on a simple USB stick. I decided to replace it with a Kingston one:

Bye bye Mediawiki

After more than 10 years using my beloved Mediawiki (wiki.deimos.fr), I decided to convert it into static html files and stop using Mediawiki :(. Why? Because maintaining a Mediawiki is a pain when you’re using a lot of extensions. In addition, I’m not using Mediawiki anymore at work, not really following the evolution, don’t want to keep maintaining php/mariadb/nginx and upgrading Mediawiki configuration can be complex as well. I really love markdown solutions generating static files like Hugo and I already did it whith my previous Wordpress.

I’m an amateur photographer and I’m using an Olympus E-M1 Mark II camera. I take photos in RAW mode to be able. For those who know me, my computer is running on Linux and I’m using Geeqie to display RAW picture. It’s a very fast and powerful solution to display them. In addition of displaying them quickly, it enhances the look and I really appreciate the rendering. Here is the original image (the first one) and the redered one by Geeqie (the second one):

  CoreOS is a lightweight Linux operating system designed for clustered deployments providing automation, security, and scalability for your most critical applications. I’ve been playing with CoreOS to replace Debian hosts which run Docker containers on Nousmotards project. CoreOS helps on simplifying bare metal deployment and avoid managing OS upgrade. As I’m still an Ansible lover, I’ve made 2 roles: CoreOS Ansible: Ansible role to deploy pypy to CoreOS to be able to get Ansible prerequisites CoreOS: Ansible CoreOS role to deploy CoreOS on bare metal servers If you want to quickly look at the result:
