Mongoose a new way to program ESP8266

In previous blogs, I have used Arduine-IDE to develop code for the ESP8266. It was a nice and convenient way, suitable for me with a background in development. Recently I came across a new technology, that I wanted to give a try: Mongoose OS Similar to my previous setup, I will be using a NodeMCU … Read moreMongoose a new way to program ESP8266

Creating a standalone instance of Eclipse Kapua using Docker containers

Today I start with taking a deeper look at Eclipse Kapua. It is a modular IoT cloud platform to manage and integrate devices and their data. My goal for the next weeks will be to demonstrate a multi-tenant capable installation of Eclipse Kapua on OpenShift, connecting several IoT devices and gateways to it. As a … Read moreCreating a standalone instance of Eclipse Kapua using Docker containers

OPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 6: CONTROLLING EGRESS TRAFFIC

OpenShift 3.3 and later contain the functionality to route pod traffic to the external world via a well-defined IP address. This is useful for example if your external services are protected using a firewall and you do not want to open the firewall to all cluster nodes. The way it works is that a egress … Read moreOPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 6: CONTROLLING EGRESS TRAFFIC

OPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 5: OPENSHIFT ROUTER

In the OpenShift world, Services take place on the OSI Layer 3 / IP, while Routing is an OSI Layer 7 / HTTP/TLS concept. Once you’ve wrapped your head around this backwards choice of naming, things are fairly easy: An OpenShift Router is a component which listens on a physical host’s HTTP/S ports for incoming … Read moreOPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 5: OPENSHIFT ROUTER

OPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 3: CONTAINER NETWORKING ACROSS OPENSHIFT NODES

So far, this sounds like a lot of effort to achieve a little more than a plain docker host – containers that can talk to each other and to the host network, potentially segregated based on kubernetes namespace. However OpenShift SDN also allows pods on different nodes to communicate with each other. To this end, … Read moreOPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 3: CONTAINER NETWORKING ACROSS OPENSHIFT NODES
