Definition of a Dockerfile to use bash scripts on a Windows 10 machine for our Cloud-Native-Starter workshop

We defined a Dockerfile to create a Docker image for our Cloud-Native-Starter workshop especially for Windows 10 users. The users can now simply create a Docker image on the local Windows 10 machine and then follow the guided steps in the hands-on workshop documentation and use the bash scripts. The reason why we don’t build a Docker image and share the image on Dockerhub is, we want to provide users the freedom of own customizations.

These are some challenges we had during the testing of the Dockerfile definition:

  • File sharing for Docker images on Windows
  • Docker port forwarding
  • Docker in Docker
  • Istio Virtual service configuration
  • Linux tools missing

Hot topics on hot days @DevOpsCon in Berlin

Hot topics on hot days @DevOpsCon in Berlin

These two days were really hot and that’s why I created that motto 😉

Here are a few pictures and a brief impression of the DevOpsCon conference in Berlin. The DevOpsCon Expo in Berlin on 11 – 14 June 2019 had approximately 800 participants and provided a full program on different technologies and methods for them.

It’s important to keep a cool head on the mission-critical topic of DevOps and make the right decisions how to deploy and deliver the optimal to achieve speed of innovation. It was awesome to see that DevOps teaming works for companies, because often we had developers and operations of one company at same time at our booth.

How to deploy a container to the IBM Cloud Kubernetes service

I want to describe another way to run the  Highscores-Service of the #BlueCloudMirror game . In the game I use  IBM Cloud Foundry apps, now I want to explore IBM Cloud Kubernetes.

Note: The #BlueCloudMirror game we  @Niklas, @Harald and I made, is available as an Pattern on IBM Developer.

The first step was creating a container for the Highscores-Service,  which I described in my blog post how to build a container.

In this post I deploy my scores-service container to the IBM Cloud Kubernetes service.  This is  not a blueprint for IBM Kubernetes deployments, if you looking for a blueprint,  just take a look hereIBM Cloud documentation contains a great guide for getting started:  How to setup and use IBM Cloud Kubernetes

I share my experiences and observations with you, along with my deployment.

Let’s start with an overview of the topics I touch in this blog post:

Simplified Architecture

The above picture shows a simplified architecture for the scores-service inside Kubernetes. You can see the relevant elements for the deployment. If you are interested in the details of  these elements, just click on the linked Kubernetes documentation.

The major elements:
