Deploy WordPress on a free IBM Cloud Kubernetes Cluster for non-productive usage

Leave a comment

In this blog post I just want to highlight an awesome guideline I noticed on GitHub: How to deploy WordPress to a free IBM Cloud Kubernetes Cluster for non-productive usage?

Why do I say “non-productive”? Because of the free IBM Cloud Kubernetes Cluster , which will be deleted after 30 days. Surely you can also deploy WordPress for production usage, when you deploy to a paid cluster. But maybe you got a feature code for free IBM Cloud at a conference or at a hackathon and you want play around with IBM Cloud, that could be one option.

You can find the instructions for the deployment here: Scalable WordPress deployment on Kubernetes Cluster. By the way, the project is under Apache 2.0 license.

Central management of billing and resource usage tracking across multiple accounts in IBM Cloud

1 Comment

In this blog post I want to shortly highlight the topic central management of billing and resource usage tracking across multiple accounts. I think it is good to know that topic, even if you will currently not use it.

I didn’t use IBM Cloud Enterprise until now, but is great to know that this is possible. This organisational topic is (more or less 😉 ) related to one of my older blog posts  “What are major elements to organize my services, apps and devices in IBM Cloud?”

The announcement was in Juli 2019 :

“Now you can organize multiple IBM Cloud accounts in flexible hierarchical groups.”

For more details please visit that blog post introducing IBM Cloud Enterprises.

No code changes needed to secure your application on Kubernetes

Leave a comment

In that blog post I want to highlight how I did my first configuration of the App Identity and Access Adapter for Istio Mixer in my Cloud Native Starter system on a free IBM Cloud Kubernetes cluster.

In my last blog post I described how I did the installation of the App Identity and Access Adapter.

Once more I want to highlight, that the cool thing from my perspective of App Identity and Access Adapter is “that the adapter can be configured to work with any OIDC compliant identity provider, which enables it to control authentication and authorization policies in all environments including frontend and backend applications. And, it does it all without any change to your code or the need to redeploy your application.”

I did a combination of the steps from the videos inside the IBM Cloud App ID service documentation and of the videos from Anton Aleksandrov. With that in mind I applied needed changes of that configurations in the videos to run it on our Cloud Native Starter setup.

Install the App Identity and Access Adapter on a free IBM Cloud Kubernetes Cluster

1 Comment

In that blog post I want to highlight that I started to integrate the open source App Identity and Access Adapter for Istio Mixer into our open source Cloud Native Starter sample that uses the free IBM Cloud Kubernetes cluster setup with a manual Istio installation.

The cool thing from my perspective of the App Identity and Access Adapter is “that the adapter can be configured to work with any OIDC compliant identity provider, which enables it to control authentication and authorization policies in all environments including frontend and backend applications. And, it does it all without any change to your code or the need to redeploy your application.” I had a short problem with the installation you can find on stackoverflow.

Create one Java Microservice with OpenLiberty and MicroProfile – made for beginners

Leave a comment

Today I created a YouTube video, where I developed one Microservice. The level of content of that video is for beginners. The video was “live” recorded and I made some minimal editing and the video takes 18 min.
The recoding is related to Java Microservices with MicroProfile and OpenLiberty in Visual Studio Code . The source code is available in the open sourced Cloud Native Starter GitHub project.

Check it out:

Maybe you are interested, how did I setup the IDE and the Project? … here are the basics.

How to connect a Cloudant database as datasource in Watson Studio?

Leave a comment

I just want to share this small information:  How to connect a Cloudant database as a datasource and use the data in Watson Studio?

You maybe have a Node-RED flow and you want to use sample IoT data from that flow in a jupyter notebook? Therefor you save the data for example in a Cloudant database and then you access the data inside Watson Studio in a jupyter notebook to work with the data. Maybe that flow could be useful in a Hackathon.

A promo code is used as a feature code @IBM Cloud

3 Comments

With this post I want to help to avoid pitfalls in wording of promo code and feature code in context with IBM Cloud.

I wrote in two blog posts about, how to enter feature codes and use them:

Sometimes you get a ” promo (promotion) code” or “feature code” at a conference or at a hackathon or on a website for free IBM Cloud usage.

So, the best definition from my point of view is:

“The promo code wording is often used for a feature code, but feature code is not a promo code.”

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

Leave a comment

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
