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” […]
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 […]
If you should have followed my previous postings ( thanks for that!! ), then you should have read my blog IMPORTING AN EXTERNAL AND NOT YET PUBLISHED DOCKER IMAGE INTO RED HAT OPENSHIFT V3, in which I have explained how to manually carry a Docker image from a non OpenShift build-server to our OpenShift infrastructure. This […]
In my previous post I described how to manually export/import a Docker image from one system into the Docker registry of OpenShift. A next step would be to push an image from a non OpenShift system directly into the registry. The documentation of OpenShift recommends to secure the registry before opening it for external access. […]
During many customer discussions on PaaS, the same question does come up: “Can I use my own Docker images in OpenShift?” While the simple answer obviously is: “Well, sure! OpenShift makes use of Docker und Kubernetes“ Making it work, is a little bit more complex – until one finally understands it. In this blog I […]
I tried to install the vagrant landrush plugin today, but received the following error from vagrant plugin install landrush 17:38 $ vagrant plugin install landrush Installing the ‘landrush’ plugin. This can take a few minutes… Bundler, the underlying system Vagrant uses to install plugins, reported an error. The error is shown below. These errors are […]
Motivation This is a follow-up on my initial posting on IaaS vs PaaS. While part 1 was an introduction into what IaaS is and how PaaS differs, this posting will look into an exemplary business-case, comparing those two approaches. The scenario and the numbers used in this business-case will be simple, as this exercise is not […]
Red Hat has released OpenShift v3 last week at the summit. Time for me to go out and explore the new features of OpenShift. I thought the beta training content would be a good starting point. Soon I had to learn, that some of the example files were not adjusted for latest kubernetes API changes. […]
What it’s all about This demo is supposed to show a lab-based version of a typical Internet of Things ( IoT ) setup. It follows a 3-Layered architecture of Edge: as created of data Controller: first level of data processing Datacenter: well, the datacenter … These layers can – and in this demo will – […]
During the last year of my customer meetings I have very often been addressed with the same scenario, which is comparing traditional ways of doing stuff ( also known as Mode 1 IT ) with more dynamic, up to date and cloud ready “Mode 2” approaches. To be more precise, I have had many discussions […]
