We have written about Kompose earlier here , when it was as young as 0.1.0. This blog post will showcase where Kompose stands now.
Kompose is a tool that converts a Docker Compose file to Kubernetes or OpenShift artifacts. Kompose was originally started as an onboarding tool for Kubernetes users by Skippbox (now part of Bitnami). It went on to receive early contributions from both Google and Red Hat.
Kompose has graduated from the Kubernetes Incubator, we reached the epic milestone of 1.0.0, and so it’s now officially part of the Kubernetes Community Project.

Today I want to introduce you to some features of OpenShift 3.6 while giving you the chance to have a hands-on experience with the Release Candidate.
First of all:
- It’s a Release Candidate and the features I’ll show you are marked as Tech Preview, so use them for testing purpose ONLY!
- We cannot use Minishift just because there is no Minishift updated yet. Anyway, I’ll show how could use its base iso-image.
- I don’t want to use ‘oc cluster up’ in a virtual machine just because setting up a virtual machine, to run it, would be a waste of time.

I’ve been using containers for nearly 3 years, initially working in the Technical Support team helping customers solve problems in their applications and giving advice about best practices to run containers. Today I work on a team where we develop containers to use in our OpenShift environment, and because of my Technical Support background, my troubleshooting skills helped me in this task. I run containers for most of my tasks and it makes my life easier. I can run any software on containers, whether for evaluation or even use in my websites. Let’s face the fact: containers are becoming more common across the companies. Google can spin up thousands of containers a day in their data centers without downtime, Netflix launches more than 1 million containers a week and many other companies, whether small or large, use containers in production to achieve a new level of scalability. Having this in mind, I’d like to list 6 main reasons why I started to use containers.

I’m assuming you’ve already tried to run some example of a multi-container application. Let’s say we have an application composed of the following:
- Web service
- Key-value store

As technology continues to disrupt the industries beyond the first wave (led by Netflix, Amazon, Uber etc.), the enterprises are embracing digital transformation to meet the challenge. One of the key technologies enabling digital transformation is Containers through its inherent advantages with packaging (Atomic, built for CI/CD), collaboration and runtime (lightweight, distributable, portable).
At the Red Hat Summit in Boston, Andrew Block and I conducted a hands-on lab on how to build a containerized intelligent Internet-of-Things (IoT) gateway on Red Hat OpenShift. The application is deployed as a set of microservices inside containers on the containerize IoT workload using microservices running on Red Hat OpenShift Container Platform.

Do you know the battery level in your smartphone is controlled by reactive software; which is software that reacts to a set of external events, such as requests, failures, availability of services, etc? This was what I recently addressed as a slideless session consisting of pure, live coding at the Red Hat Summit this past May.

Red Hat Container Development Kit (CDK) provides a Container Development Environment (CDE) that allows users to build a virtualized environment for OpenShift. This environment is similar to the user’s production environment and does not need other hardware or a physical cluster. CDK is designed to work on a single user’s desktop computer.
