Rapidly spinning up a VM with Ubuntu and k3s (with the Kubernetes Dashboard) on my Windows laptop using Vagrant and Oracle VirtualBox
In November of last year, my colleague Lucas Jellema, wrote an article with the title “Ultra fast, ultra small Kubernetes on Linux – K3S beating minikube”. [https://technology.amis.nl/2019/11/12/ultra-fast-ultra-small-kubernetes-on-linux-k3s-beating-minikube/] For training and demo purposes, on my Windows laptop, I already had an environment with a guest Operating System, Docker and Minikube available […]
Resolving issue: Oracle Virtual Box and Windows 10 – Call to WHvSetupPartition failed VERR_NEM_VM_CREATE_FAILED
Like so many colleagues and fellow developers around the world, the latest Windows Update also messed up my machine’s ability to successfully run Oracle Virtual Box. When running vagrant to provision a VM, I ran into messages such as: Failed to open a session for the virtual machine. Call to […]
Using Elastic Stack, Filebeat and Logstash (for log aggregation)
In a previous article I described how I used ElasticSearch, Filebeat and Kibana, for log aggregation (getting log information available at a centralized location). [https://technology.amis.nl/2019/09/15/using-elastic-stack-filebeat-for-log-aggregation/] In this article I will talk about the installation and use of Filebeat in combination with Logstash (from the Elastic Stack).
Using Elastic Stack, Filebeat (for log aggregation)
In my last article I described how I used ElasticSearch, Fluentd and Kibana (EFK). Besides log aggregation (getting log information available at a centralized location), I also described how I created some visualizations within a dashboard. [https://technology.amis.nl/2019/05/06/using-elasticsearch-fluentd-and-kibana-for-log-aggregation/] In a new series of articles, I will dive into using Filebeat and […]

Using Vagrant and shell scripts to further automate setting up my demo environment from scratch, including ElasticSearch, Fluentd and Kibana (EFK) within Minikube
For training and demo purposes, on my windows laptop, I needed an environment with a guest Operating System, Docker and Minikube available within an Oracle VirtualBox appliance. So, in a series of articles up till now, I described the following: The steps I took, to get Docker and Minikube (using […]
Using Helm, the package manager for Kubernetes, to install two versions of a RESTful Web Service Spring Boot application within Minikube
In my last article I described how two versions of a RESTful Web Service Spring Boot application were used in Minikube, together with an external “Dockerized” MySQL database. [https://technology.amis.nl/2019/03/05/using-a-restful-web-service-spring-boot-application-in-minikube-together-with-an-external-dockerized-mysql-database/] In this article I will describe how you can use Helm, the package manager for Kubernetes, to install two versions of […]
Using a RESTful Web Service Spring Boot application in Minikube, together with an external “Dockerized” MySQL database
In a previous article, I talked about an environment, I prepared on my Windows laptop, with a guest Operating System, Docker and Minikube available within an Oracle VirtualBox appliance.

Rapidly spinning up a VM with Ubuntu, Docker and Minikube (using the –vm-driver=none option) on my Windows laptop using Vagrant and Oracle VirtualBox
For training and demo purposes, on my Windows laptop, I needed an environment with a guest Operating System, Docker and Minikube available within an Oracle VirtualBox appliance. In this article, I will share with you the steps I took, to get Docker and Minikube (using the –vm-driver=none option) installed on […]
Minikube on Windows. Hyper-V vs Vagrant/VirtualBox
Kubernetes is a system for running and coordinating containerized applications across a cluster of machines. Minikube runs a single-node Kubernetes cluster and can be used for local development. In this blog post I’ll compare 2 different ways to get a working Minikube environment on Windows based on experience with a […]
VirtualBox networking explained
VirtualBox networking is extremely flexible. With this flexibility comes the challenge of making the correct choices. In this blog, the different options are explained and some example use cases are elaborated. Access between guests, host and other members of the network is explained and the required configuration is shown. This […]
Running Kafka, KSQL and the Confluent Open Source Platform 4.x using Docker Compose on a Windows machine
For conducting some experiments and preparing several demonstrations I needed a locally running Kafka Cluster (of a recent release) in combination with a KSQL server instance. Additional components from the Core Kafka Project and the Confluent Open Source Platform (release 4.1) would be convenient to have. I needed everything to […]
Rapidly spinning up a VM with Ubuntu and Docker–on my Windows machine using Vagrant and VirtualBox
I have a Windows laptop. And of course I want to work with Docker containers. Using the Docker Quickstart Terminal is one way of doing so, and to some extent that works fine. But whenever I want to have more control over the Linux environment that runs the Docker host, […]
First steps with Docker Checkpoint – to create and restore snapshots of running containers
Docker Containers can be stopped and started again. Changes made to the file system in a running container will survive this deliberate stop and start cycle. Data in memory and running processes obviously do not. A container that crashes cannot just be restarted and will have a file system in […]
Get going with Project Fn on a remote Kubernetes Cluster from a Windows laptop–using Vagrant, VirtualBox, Docker, Helm and kubectl
The challenge I describe in this article is quite specific. I have a Windows laptop. I have access to a remote Kubernetes cluster (on Oracle Cloud Infrastructure). I want to create Fn functions and deploy them to an Fn server running on that Kubernetes (k8s from now on) environment and […]
