I have a passion for all things open source. I live in Ipswich MA and work for Red Hat, on the fabric8 project. Fabric8 is a cloud micro-services platform so you can deploy your applications to an all open source cloud. I kayak on the Atlantic Ocean along the coastal North East from Massachusetts to Maine whenever I can.
Summery - Every kubernets service has different endpoints for the same service. Four scenarios are outlined that explain when to use what endpoint, depending on if the client is deployed on the kubernetes cluster or externally and/or if an API manager is used. Introduction We use Openshift as our Kubernetes implementation. Before we talk about calling a service, let’s first talk about deplo…
The KUBERNETES_DOMAIN is defaulted to vagrant.f8 in Fabric8, and if you forgot to set this system parametes before running the fabric8 install then you end up with routes containing the vagrant.f8 domain. To fix this you will have to reinstall the console. First export KUBERNETES_DOMAIN=<yourdomain> oc delete route fabric8 oc delete rc fabric8 systemctl stop openshift docker kill <fabric…

In this post I will show you how to deploy a REST quickstart to Fabric8 and how to publish it as a Public Service on th…
1. Updated version There is an updated version of this proposal, see https://kurtstam.github.io/2015/10/15/Update-1-Proposal-for-Kubernetes-Service-Annotations.html 2. Problem description Service URL - Every Service has one (or more) endpoint. As a rule the endpoint should be located at the root "/" of the localtion URL, i.e. http://172.100.1.52/. There are cases where this is not possible and th…

The fabric8 console is written in docker and the source lives on github at: https://github.com/fabric8io/fabric8-console. To package the console up as a docker container first run gulp site and then to create and deploy the docker container use docker build -t fabric8/fabric8-console:<version> . where <version> is the version you want it to have in your docker repository. Now you are…
I just returned from the London MicroServices Architecture Developer Day. Attendence was really great and the tickets actually sold out. Here is nice writeup if you missed it. Marc Savy and yours truly presented API Management on Kubernetes. If you want to follow along you need to deploy the ElasticSearch app, the Fabric8-HTTP-Gateway app and the APIMan app - in that order. If all goes well the A…
The default Ubuntu image has a dynamically sized 40 GB harddrive. You may find that if you are working with Docker images, that this space fills up quickly. Before you start download the GParted iso. 1. Resize the vmdk file VirtualBox cannot resize a vmdk file. Instead you will need to change over to use the vdi format, then resize (to 100 GB) and finally create vmdk formatted clone of this. Make…
The full fabric8 docs can be found here. Here I took the relavant sections applicable to running on OSX, and I added some notes. OpenShift v3 relies on Docker for its container management. OSX does not support Docker natively. The recommended way is to use vagrant to create a VM with the correct Docker configuration. 1. Prerequisites Install whatever the newest version is of the following: Docker…
