At work, I got a terrible issue with adding the AWS support to the OpenShift cluster. I really got confused as well as I was explicitly setting the nodename for this server. But whatever value I was putting in the config, it was never working, it always registered the node as the specific instance name that amazon would have given. But why??? Let’s have a look. The homicide A long time ago, a nice little instance in AWS called node00.

With the massive adoption of the “Cloud”, different tools are borned to simplificate dev / sys. admins lifes. These tools created a new way of dealing with infra, the Infrastructure as Code aka IaC.

The big plus to use those is that with a simple API call you can provide, provision and destroy infrastructure at your glance.

Hi all, after few minutes of frustration I finally got the django debug toolbar showing in my django apps running in docker managed by docker-compose. This issue happened to me quite a few times now and it really pisses me off to not know why this is happening. And that was a really simple issue… The Issue If you started to dockerize your django app, I am sure that you encountered some weird difficulties that you managed to fix after few google requests.

First of all this issue is appearing because I enabled the multilib support in my arch config (https://wiki.archlinux.org/index.php/multilib). To fix this problem you need to have all your gcc packages using multilib or none of them, not both. First let’s find out which packages you need to remove/install with the multilib support. Run: 1 sudo pacman -Qs gcc You should have an output like:

As you could have seen in the previous post, docker is quite handy to make your application running EVERYWHERE. So now the problem you can have is, how do you actually dockerize your application.

Define the requirements of your application It can sound a bit a cheap advice, but before to start everything you need to identify and isolate what your application needs.

Wow, big subject here. Docker. So what’s docker? Docker will help you to deploy applications without worrying about the installation or the host you want to run it on.

Hi everyone, today we’ll see how to automatize every new functionality that we’ll build in our little ionic app to the Google Play. Server configuration Firstly, we’ll install all the dependencies on the server where’s Jenkins. Ionic installation sudo npm install -g ionic@beta Here I use the beta version of ionic (to use angular 2 =D), so you can remove the @beta if you’re on a v1 project. Cordova installation sudo npm install -g cordova JDK installation Here, it will depend on your linux distribution.

Hi! Are you near to create a new API, and you don’t know which framework to use? If this API will be added to a django project, the django rest framework will be perfect to create this API with few lines of code! What’s a REST API?

The main point of using a REST API is that we’ll have a separation between the client and the server.

Hi everyone, there’s a long time ! Today, we’ll see the performance testing framework gatling which I could use during my intership of end of studies and I’ll show you how easy to use it is!

Since the popularization of git for IT projects, it became the most used tool for your project. With this phenomen, new services has been created as GitHub and Bitbucket (for the most known). The first one is focused on the social aspect and the second one is based on his privatisation of the projects (I’m only speaking about free offers). One way the most secure to keep its code was to install a proper git server managed with GitLab or GitBlit.

If you asked yourself the same question as me “How could I serve my static files for different languages ?", so this post is exactly for you ! Let’s see how I did. Which file tree should we choose ?
