From Kubernetes to Gitlab-ci in less than 10min

Sat, 16 May 2020 22:32:04 +0000

I have been playing a lot with Kubernetes lately, from creating a cluster from scratch on bare metal, setting up a ELK stack, Prometheus metrics to setting up a CI/CD using Gitlab CI.

I found the last one so easy that I made a video for it.

I have been using a DigitalOcean Kubernetes cluster for this video, it was super easy and I got $100 to play with it for 60 days.

Docker: Multi-stage & Caching

Tue, 21 Apr 2020 05:00:50 +0000

Multi-stage

In the beginning

When we first started to build docker images, long before the multi-stage syntax, our projects would look something like this:

We would have a base docker image containing the dependencies shared by the development and the production image, then one file for each final image.

The script build.sh shows that we first build the base image tagging it as base_image, then depending of the argument passed to the script we would build the final image.

Minecraft 1.15 power by docker

Wed, 15 Apr 2020 06:05:40 +0000

Few years ago I created a docker image for me to play on Minecraft with friends.

I have been updating this image from time to time but basically it’s almost always compatible with the new version since it’s building the game server from the sources.

The project can be found here: https://github.com/AshDevFr/docker-spigot

The docker image can be found here: https://hub.docker.com/r/ashdev/minecraft-spigot

I provide the image with an ubuntu base or an alpine base which is much smaller.

Hands-on Docker in Paris the 22nd of March (Docker's 3rd birthday)

Tue, 23 Feb 2016 12:51:00 +0000

Edit: Due to the Docker Meetup in Paris, the Hands-on Docker is rescheduled to the 22nd of March instead of the 24th of March.

Hi!

Few months ago, I gave a talk about Docker (the article). During this talk I saw that a lot of people are really interested by Docker but did not know where to start.

So, I decided to create a Hands-on Docker to help them understand how to use it. As front end developer, the hands-on will be nodeJS/mongoDB oriented. The same principle could be applied to anything (Java, php, …).

Talk about Docker

Fri, 06 Nov 2015 13:13:01 +0000

Few weeks ago, as every month, my company has organised their Tech evening. This time, it was about Docker.

As a long time user of virtualization and for the past year of Docker, I offered to talk about how to integrate docker in our everyday work.

As a front end developper, I use very often Gulp, Grunt and/or Node.js in my projects. These tools are pretty awesome but when I deal with external libs I have to be really careful of what I put in my dependencies file.
