OpenShift Networking from a container/workload point of view – Part 2: Container Networking on an OpenShift Node

In OpenShift, networking is equally simple from a container point of view. Within the container’s namespace there is a eth0 network interface configured and services such as DNS just work. You can still use dedicated NICs on the host to isolate specific types of traffic. What’s the difference? It turns out there is hardly any […]

OpenShift 3.1 Networking from a container/workload point of view – Part 1: Container Networking on a plain Docker Host

From a container point of view, networking on a plain Docker Host is simple. A running container is nothing more than a Linux process which is namespaced and constrained with regards to access (SELinux) and resource consumption (cgroups). In each namespace, there is a single (virtual) network interface called eth0 which is assigned an IP […]

All in One IoT Demo with JBoss Fuse, BPM Suite and BRMS

This is part 5 of my IoT series of blogs. So far we did look at the following topic Introduction into the planned scenario Building a Raspberry Pi based Smart Gateway ESP8266 and DHT22 based smart sensor Putting the Smart into the Smart IoT Device In this blog we will create a first running version of […]

Building the IoT Smart Gateway with Docker, Raspberry Pi and JBoss for the “lazy” ones – Ansible rules!

If you have followed my earlier posts, then you know, that I’m in the process of building an IoT Demo, with a Raspberry Pi2  as the Smart Gateway. During this process, I had to re-install my Raspberry multiple times, but after the second time I got a bit tired of doing the same steps over […]

Putting the Smart into the Smart IoT Device

This is part 4 in my IoT series of blogs. The first parts did cover the following topics: Introduction into the planned scenario Building a Raspberry Pi based Smart Gateway ESP8266 and DHT22 based smart sensor This blog will describe how to enable the Smart Gateway to handle, enhance and forward incoming messages. As for […]

Building a Raspberry Pi based Smart Gateway for IoT

As described in my previous post, my intention is to create a new version of my IoT Demo. The first element that I wanted to get up and running is the Gateway, which is supposed to run a MQTT broker to receive and forward messages a transformation capability to change messages, enable smart routing of […]

Red Hat IoT Demo – Next Generation

After having done a pure Docker/JBoss based IoT Demo-Environment I felt like it was time to bring this demo to the next level, but what does that mean? For me it means to become a bit more “realistic” and to integrate more and different technologies into the demo. In hard facts, this mean real, “dumb” […]

First Fuse application on OpenShift V3.1

Since mid of December 2015, Red Hat has released the initial version of the Fuse Integration Services. These are various pre-build images which are aimed to make the implementation of Red Hat JBoss Fuse applications on OpenShift V3 as seamless as possible. In this blog I will document the steps required to create a first […]
