In this blog post I want to briefly show, how I implemented the upload of an user to Keycloak with CURL in a bash script.
I came across a helpful blog post (Keycloak REST API: Create a New User), but this blog post didn’t contain the information: How to set the password for the user?

This is a short cheat sheet about, how to simply examine a JSON response from a Cloudant search in Java. I found different examples, but these examples were (more or less) older examples, where I missed some pieces and at the end for me the Java EE documentation was the best resource to realize it.
The JSON I wanted to examine, was a JSON with a nested JSON array and that array also contains a nested JSON.

This is a “simple” cheat sheet, how to create a single virtual server instance (VSI) in the virtual private cloud (VPC) infrastructure on IBM Cloud using Terraform.
“Terraform is to write infrastructure as code using declarative configuration files. HashiCorp Configuration Language (HCL) allows for concise descriptions of resources using blocks, arguments, and expressions.” resource Terraform
There is an awesome documentation on IBM Cloud to do this:
That blog post reuses a lot of the content in the IBM Cloud documentation. You need to install Terraform and and clone the example GitHub project as your example terraform project folder.

It’s awesome we just created 10 hours of live recordings, which are built on experience, about application security. That learning journey was made by the IBM Developer Hybrid Cloud Build Team from IBM and I am a part of that team. We put together great content for you. By the way, I was responsible for the content ;-). I also have been the moderator for most of the sessions and I also gave sessions by myself. The learning journey is called #ApplicationSecurityLearningJourney.
So just take something to drink and grep some snacks and then enjoy all of the knowledge or just select your point of interest.
Here are the links to the various topics and related recordings on Crowdcast.io.
This is a “simple” cheat sheet, how to create a single virtual server instance (VSI) in the virtual private cloud (VPC) infrastructure on IBM Cloud.
The blog post has four major sections:
virtual server instance inside the VPC networkvirtual server instance from a local machineFor more information, please visit the VPC IBM Cloud documentation.

I just found a useful configuration for the Visual Studio Code terminal tabs. If you don’t like this new configuration to manage the tabs you see in the gif below:
Here is a good 10 min video about “Creating and Destroying an Instance using IBM Cloud Virtual Servers” by using the IBM Cloud classic infrastructure. The video contains essential practical basics and is created by LearnToday. The screen resolution is not the best, but it’s ok.

This blog post addresses the topic, how to use environment variables to make a containerized Vue.js frontend application more flexible. We will touch following technologies Vue.js, NGINX, JavaScript, Dockerfile and Code Engine.
When you run a containerized application on a container orchestration platform like Kubernetes, Open Shift or on a serverless frameworks like Knative or Code Engine or other platforms, it’s helpful to pass endpoints to other applications to the containerized application by using environment variables. When the container will be restarted, these variables can be provided to the container and no adjustment in the source code is necessary. You can use configmaps or in Code Engine simply the environment variable itself.
The example source code you find in this workshop.
In addition, it’s useful when you take a look into this awesome blog post: Externalise and Configure Frontend Environment Variables on Kubernetes which was used for the starting point for the configuration.

This blog post addresses the topic, how to use environment variables to make a containized Quarkus application more flexible. We will touch following technologies Quarkus, OpenJ9 Java runtime, MicroProfile, Dockerfile definition and Code Engine.
When you run a containerized application on a container orchestration platform like Kubernetes, Open Shift or with a serverless framework like Knative or Code Engine or on other platforms, it is helpful to pass endpoints to other applications to the containerized application by using environment variables. When the container will be restarted, these variables can be provided to the container and no adjustment in the source code is necessary. You can use configmaps or in Code Engine simple the environment variable itself.
We will follow along an application example for the implementation and the example source code you find in the Get started to deploy a Java Microservices application to Code Engine workshop. (or the direct link to the used file in the GitHub repository is provided in the blog post itself)

Code Engine is build to create modern, source-centric, containerized, and serverless apps and jobs.
Take a quiz to get started with the Code Engine terminology.
The topic batch jobs is more related to AI and machine learning, and run AI model training temporarily with highly workload, and thats at the moment not so much in my scope.
My starting point with Code Engine was in my YouTube video: Code Engine, Containerized Application, Node-RED Starter Kit and Scale To Zero. With that in mind, from my perspective Code Engine is a very good starting point for smaller containerized applications, because you can precisely control costs with scale to zero. … and by the way, it’s easy of use.
That motivated me to create a simple hands-on workshop, where you are guided to deploy the Cloud Native Starter security example application to Code Engine. The source code of the example application is included to the GitHub project of the workshop.
