One of the labs in our Weblogic Advanced Administration 12c course is about using domain templates. When revising the particular lab, we created a domain in Weblogic 12c and then created a template based on the domain. On recreation of the domain based on the template we get an exception: This we get regardless of if we provide nodemanager details at the initial creation of the domain. We did some investigation and found for instance this forum, that gave a hint, but not a...

This tutorial walks through how to use a custom Docker image to define an Fn function. Although Fn functions are packaged as Docker images, when developing functions using the Fn CLI developers are not directly exposed to the underlying Docker platform. Docker isn’t hidden (you can see Docker build output and image names and tags in routes), but you aren’t required to be very Docker-savvy to develop functions with Fn. However, sometimes you need to handle advanced use cases...

As we saw in this post, it is really simple to write and deploy Serverless Kotlin functions using Fn. The Kotlin support is, in Fn, largely based on the Java support and more specifically on the Java FDK. The initial Fn Kotlin support was a bit different than it is today as it was using the kotlinc compiler in a Docker (build) image. That approach has been recently replaced (from CLI 0.4.129) in favor of Maven using the regular Java FDK images. The only real difference...

One of the neat features of Fn is that you define your functions as container images. Fn isn’t prescriptive about what goes into the container as long as you can read requests and write responses — anything you package in a container that can read from STDIN and write to STDOUT can be a function. This flexibility sets Fn apart from other FaaS platforms which typically only offer a small set of supported languages. Fn encourages you to use whichever language you are most...

In my last post I wrote about general concepts behind Function as a Service (FaaS) and my view on this application development style. As an example I used the basic pipes and filters concept implemented by Unix Shells and many shell commands. Within this post I will use the same example and implement it using a Function as a Service platform. To recap the scenario, we had a simple JSON file containing booking records. From this file we identified certain records based on...

This is the first blog in the series to come, which will help you understand, how you can build a NodeJS REST microservice application Docker image and push it to DockerHub using Oracle Developer Cloud Service. The next blog in the series would focus on deployment of the container we build here to deploy on Oracle Kubernetes Engine on Oracle Cloud infrastructure. You can read about the overview of the Docker functionality in this blog. Technology Stack Used Developer Cloud...

In the last few years lightweight and flexible technologies and architectures become the predominant approach for enterprise applications. Besides Microservices, Function as a Service (FaaS) or Serverless Programming is a commonly discussed topic. Some see FaaS as an addition to today’s lightweight architectures, others see it as next step within the evolution of Cloud and IT. Throughout the last few months I had many interesting discussions regarding FaaS and recognized...
