OpenSource Traefik ratings with Matomo

Some time ago, I talked to you about tracking and why I care about my privacy. In my conclusion, I indicated that user tracking was still a useful tool for a company, as long as it was ethical and respectful of users.

However, very often, I see that Google Analytics is used by the sites I browse on. It is far (even very far) from being respectful of your users’ data. Even worse! You allow Google to know the activity of your site from end to end and to know how to better target its ads (among others).

Create a local Kubernetes cluster with Vagrant

Tue, 15 Sep 2020 07:00:57 +0000

Testing Kubernetes is quite easy thanks to solutions such as Minikube.

However, when you want to test cluster-specific features, such as load balancing or failover, it is not necessarily suitable anymore.

It is possible to build your Kubernetes infrastructure on servers, or by using managed services from a cloud provider (Kapsule at Scaleway, AKS at Azure, GKE at GCP or EKS at AWS for example).

Nevertheless, these solutions cost money. When you just want to test functionalities or self-training, it’s not necessarily appropriate.

Traefik 2.3 : Towards plugins and beyond!

Thu, 23 Jul 2020 06:38:07 +0000

Traefik 2.3 (codename: Picodon - picodon is a cheese, which you can see in the banner of this article) is available as a release candidate since a few days. More than a simple version increment, it brings a lot of new features.

Two big new features caught my attention:

The new service of Traefik : Traefik Pilot
Adding plugin management

Another new feature, compatibility with ECS will be covered in a future article.

Why and how I got rid of Disqus

Mon, 20 Jul 2020 08:00:00 +0000

Lately, I’ve made some changes to this blog, discreetly. One of the main changes is the management of comments, goodbye Disqus, hello Commento. I’ll explain why…

A bit of history of this blog

At the beginning (I’m talking about February 2019, not old times) of this blog, my goal was rather simplistic: I wanted to share my knowledge, my vision on certain subjects and talk about anecdotes of all kinds. A year and a half and forty posts later, goal achieved!

Accelerate the test of your lambda functions with Docker

Mon, 27 Apr 2020 06:00:00 +0000

Lambda is a very powerful AWS tool. Executing scripts in serverless mode drastically reduces the cost and complexity of managing a scalable infrastructure, however, testing its functions directly on Lambda can sometimes be frustrating as it requires round trips between the development station and the AWS environment.

There are testing features built into the AWS toolkit for the most popular editors (for Microsoft Visual Studio Code / PyCharm, for example), however, this restricts the possible editors and creates an adherence that is not particularly desirable.

Traefik 2 - Reverse proxy in Kubernetes

Wed, 01 Apr 2020 20:01:29 +0000

Today, we deploy more and more applications and micro-services in Kubernetes. Managing all the entry points of these applications can be problematic. To facilitate this management, there are ingress controllers, Traefik is one of them.

Disclaimer : This post is a translated version of the blog post I made for my company, you can find the french version here, on WeScale blog.

Traefik 2 - One ingress controller to control them all

Traefik 2 - TLS Configuration (Rank A+ on SSLLabs)

Mon, 03 Feb 2020 06:50:00 +0000

Disclaimer: Due to the descriptions I give below, this post will be longer than my usual posts.

Security is everyone’s business. As a security architect, I’m quite sensitive to these subjects.

As I talked about it recently, I migrated the reverse proxy of this blog from Traefik 1 to Traefik 2 recently. So I decided to configure the TLS part afterwards, my goal being to have a secure site (and therefore safe for my users) by letting Traefik manage all this part.

Extraction of Traefik accesslogs and dashboard creation

Thu, 16 Jan 2020 20:21:00 +0000

A few weeks ago, I wrote an article explaining the migration from Traefik 1 to Traefik 2, but this time I propose to address a crucial point in the implementation of an application, its monitoring.

This article explains how I set up my dashboarding, it doesn’t explain in any case the “enterprise” dashboarding that should be more reliable and complete on some points.

During this article, I will explain how to create this type of dashboard in a very basic way.

Small migration guide from Traefik 1 to Traefik 2

Mon, 06 Jan 2020 06:03:56 +0000

I recently moved the front of this blog from Traefik 1 to Traefik 2, and to say the least, it’s no picnic.

My Traefik use case

I use Traefik as a load balancer/reverse proxy front in a Kubernetes infrastructure. My use is very basic. Depending on certain path and/or domain, I redirect to separate pods. In the case below, I will consider that I have only one pod, this blog. I also manage my certificates with Traefik via Let’s Encrypt.

How to install Docker on a Raspberry Pi

Mon, 15 Jul 2019 17:13:20 +0000

I have a number of raspberries at home, these microcomputers the size of credit cards. Small and powerful, they have many uses, such as having a mediacenter on a TV set too old to do it natively.

I even recently fell for the Raspberry Pi 4 released last month (I’m weak against a new toy) to turn it into an application server, with its 4Gb of RAM, there’s plenty to do.
