We are pleased to announce the release and open sourcing of the Technology Preview version of the Oracle WebLogic Server Kubernetes Operator! We are releasing this Operator to GitHub for creating and managing a WebLogic Server 12.2.1.3 domain on Kubernetes. We are also publishing a blog that describes in detail how to run the Operator, how to stand up one or more WebLogic domains in Kubernetes, how to scale up or down  a WebLogic cluster manually or automatically using the WebLogic Diagnostics Framework (WLDF) or Prometheus, how the Operator manages load balancing for web applications deployed in WebLogic clusters, and how to provide integration for managing Operator logs through ElasticSearch, logstash and Kibana.

A Kubernetes Operator is "an application specific controller that extends the Kubernetes API to create, configure, and manage instances of complex applications".

We are adopting the Operator pattern and using it to provide an adapter to integrate WebLogic Server and Kubernetes, allowing Kubernetes to serve as a container infrastructure hosting WebLogic Server instances. And so the WebLogic Server Kubernetes Operator is an operator that extends Kubernetes to create, configure, and manage a WebLogic domain. Read the complete article here.

In a previous series of blog posts titled Exploring Github DockerHub and OCCS I walked through how to setup your development environment, install Docker, create a git project, link Docker Hub and GitHub accounts, trigger a build of a docker image on Docker Hub and then deploy and run the docker image using the Oracle Container Cloud Service.

In this blog I wanted to do something similar but this time focus on a more simplified process so that a less technical user could follow the steps without the need for a development environment. The way I have structured this post mans that you can follow every step using a web browser. I have attempted to focus more on consuming the dockerised application that a developer has already built. For the purpose of this exercise I am using the example Medical Records application that some of you may be familiar with from some of my previous blog posts. For those not familiar with the application, it consists of a Node.js web application that interacts with a MongoDB database. The web application surfaces a number of REST APIs (eg Get / POST Patient , GET / POST Physician, GET/POST Observations etc), and uses Swagger UI so that the REST APIs can be quickly interacted with by the end user.

If you want to follow the steps in this blog post you will need a login for GitHub and Docker Hub and also a subscription or trial account for the Oracle Cloud in order to use the Oracle Container Service Classic (OCCS). Read the complete article here.

In one of my previous posts I described how to create a Docker container serving as a builder machine for ADF applications. Here I am going to show how to use this container as a function on Fn platform.
First of all let’s update the container so that it meets requirements of a function, meaning that it can be invoked as a runnable binary accepting some arguments. In an empty folder I have created a Dockerfile (just a simple text file with this name) with the following content:

FROM efedorenko/adfbuilder

ENTRYPOINT ["xargs","mvn","package","-DoracleHome=/opt/Oracle_Home","-f"]

This file contains instructions for Docker on how to create a new Docker image out of existing one (efedorenko/adfbuilder from the previous post) and specifies an entry point, so that a container knows what to do once it has been initiated by the Docker run command. In this case whenever we run a container it executes Maven package goal for the pom file with the name fetched from stdin. This is important as Fn platform uses stdin/stdout for functions input/output as a standard approach. In the same folder let’s execute a command to build a new Docker image (fn_adfbuilder) out of our Docker file: Read the complete article here.

I have a cluster of Raspberry Pi for my pet-projects and believe that serverless is very good for home automation. Couple months ago I started to use Fn Project. But currently we can’t use standard way to install it on computers with arm32 architecture. Next I’ll explain some custom steps to run Fn on your Raspberry Pi and call Java function.

Step 1: Prepare environment

As you might know Fn consists of several components. To run Java-function we’ll use following:

• Fn Server;
• Command line interface;
• Java function development kit.

To run functions you have to install docker. Read the complete article here.

One of our main objectives with the Fn Project is to have a very easy and elegant user experience. From your first touch with our quickstart to building and deploying complex applications, we want to make the experience drop dead simple. Deploying a single function has always been easy — fn deploy — and now you can deploy an app consisting of any number of functions almost as easily.

First, make an app.yaml file and put it in the root directory of your application, eg:

name: myawesomeapp

You should organize your Fn application code in a directory structure that matches your endpoints, for example: Read the complete article here.
