Docker 101 – Extra bonus

Well, sometimes life is wonderful and sometimes sucks. Sometimes all of this happen simultaneously. While I was writing the awesome previous posts (mind you, AWESOME), Docker released a new stable version with some important changes. So I found myself deprecated. In a single week.

You were noticed about some of the new stuff, the new networking system, but there are more changes, like volumes and a “version2” of docker-compose.yml to deal with all the changes. Enough for an entire post. So let’s go through the changes.

Docker 101 – docker-compose

Third post of this Docker 101 series. We’ve seen what containers are, how to build them, how to run them, how to manage visibility. All of this under the docker command.

In this post we’re learning about docker-compose which, according to the official documentation is a tool for defining and running multi-container Docker applications.. Just what we need right now!

Docker 101 – Dockerfile

This is the second post of the Docker 101 tutorial; you can check the first one if you missed it. So far we have installed Docker, we’ve made a couple of different “Hello, world” with Docker and we have learnt basic modes of running (interactive, daemon).

This new post is meant to introduce a new scenario of use (more real, but still simple), and the Dockerfile; so we’ll learn how to build custom images.

Let’s go!

Docker 101 – Hello, world


This post is a tutorial covering the very basics of Docker. Its goal is to offer a way to start with Docker and containers, and some concepts and tips about how to use it.

Disclaimer: I’m not an expert; on the contrary, I have just started learning, like the past week. Because of this specific situation, I know what is being useful for me to learn Docker. Many of the 101 tutorials are just too difficult (for me!), and this aims to be clear, even if it’s not too ambitious.

Let’s start!

IX PIWEEK: monitoring with ELK (I)

Yesterday started the Piweek IX, 9 times showing what a small company can do about innovation. Twice a year. You can follow us on twitter.

For this edition, I left aside my tradicional taste for Arduino and wanted to try a well known technology for monitorization (ELK). And I was very happy to know that my colleague Alex wanted to be part of the experiment.

As usual, I’m trying to build some useful information out from my learning process, so here you have a serie of posts about how to run ELK (Elasticsearch, Logstash, Kibana).
