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:
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):
For my own company MySocialApp, I’m managing multiple Cassandra clusters on top of a Kubernetes on premise cluster. For those who never heard of this distributed database, here is the summary from the official website:
The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.
I’m using Kubernetes on an on premise cluster for MySocialApp. Today, I’m storing MySocialApp public images at Quay.io and I also wanted to store private images. I didn’t want to bootstrap a private registry for it to avoid maintaining it, having a distributed storage to maintain for it etc…but wanted a solution at a lower cost.
I started to look at DockerHub and Quay.io. As far aas I saw, DockerHub do not provide private registry while Quay does.
The Jeedom software is open source; you have complete access to the software that manages your home automation. Jeedom is compatible with various protocols, like Z-Wave, RFXCOM, RTS SOMFY, EnOcean, xPL, etc.
Installing Jeedom on Synology with Docker it not a complex task. However for those who are not familiar with those technologies, I summarized here the installation process for a Z-wave network.
First of all, let’s look at the requirements:
Traefik (pronounced like traffic) is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. It supports several backends (Docker, Swarm, Kubernetes, Marathon, Mesos, Consul, Etcd, Zookeeper, BoltDB, Eureka, Amazon DynamoDB, Rest API, file…) to manage its configuration automatically and dynamically.
In a previous post, I explained how to manually deploy it in HA mode. For MySocialApp (iOS and Android social app builder - SaaS), I had to automate it.
