In previous articles, I have talked about using Docker Containers in smart testing strategies by creating a container image that contains the baseline of the application and the required test setup (test data for example). For each test instead of doing complex setup actions and finishing of with elaborate tear […]

Handle a GitHub Push Event from a Web Hook Trigger in a Node application
My requirement in this case: a push of one or more commits to a GitHub repository need to trigger a Node application that inspects the commit and when specific conditions are met – it will download the contents of the commit. I have implemented this functionality using a Node application […]
Node & Express application to proxy HTTP requests – simply forwarding the response to the original caller
The requirement is simple: a Node JS application that receives HTTP requests and forwards (some of) them to other hosts and subsequently the returns the responses it receives to the original caller. This can be used in many situations – to ensure all resources loaded in a web application come […]
Create a Node JS application for Downloading sources from GitHub
My objective: create a Node application to download sources from a repository on GitHub. I want to use this application to read a simple package.json-like file (that describes which reusable components (from which GitHub repositories) the application has dependencies on) and download all required resources from GitHub and store them […]
Oracle JET Web Applications – Automating Build, Package and Deploy (to Application Container Cloud) using a Docker Container
The essential message of this article is the automation for Oracle JET application of the flow from source code commit to a running application on Oracle Application Container Cloud, as shown in this picture: I will describe the inside of the “black box” (actually light blue in this picture) where […]
Microservices and Updating Data Bound Context on Oracle Cloud with Application Container and Event Hub (plus DBaaS and MongoDB)–Part Two
This article describes – in two installments – how events are used to communicate a change in a data record owned by the Customer microservice to consumers such as the Order microservice that has some details about the modified customer in its bound context. The first installment described the implementation […]
Microservices and Updating Data Bound Context on Oracle Cloud with Application Container and Event Hub (plus DBaaS and MongoDB)–Part One
This article describes – in two installments – how events are used to communicate a change in a data record owned by the Customer microservice to consumers such as the Order microservice that has some details about the modified customer in its bound context. The microservices are implemented using Node. […]
Prepare and link bind Oracle Database Cloud, Application Container Cloud, Application Container Cache and Event Hub
A fairly common combination of Oracle Public Cloud services that I use together – for example for the implementation of microservices – is DBaaS, Application Container Cloud, Application [Container] Cache and Event Hub. In this article, I show the sequence of steps I went through in the Oracle Public Cloud […]
Tweet with download link for JavaOne and Oracle OpenWorld slide decks
In a recent article I discussed how to programmatically fetch a JSON document with information about sessions at Oracle OpenWorld and JavaOne 2017. Yesterday, slidedecks for these sessions started to become available. I have analyzed how the link to these downloads were included in the JSON data returned by the […]
Setting up Oracle Event Hub (Apache Kafka) Cloud Service and Pub & Sub from local Node Kafka client
Oracle offers an Event Bus Cloud Service – an enterprise grade Apache Kafka instance – with large numbers of partitions and topics, (retained) messages and distributed nodes. Setting up this cloud service is simple enough – especially once you know what to do, as I will demonstrate in this article. […]
Rapid and free cloud deployment of Node applications and Docker containers with Now by ZEIT
I was tipped off about this now service from ZEIT: https://zeit.co . A cloud service with free tier that allows command line deployment of a simple static website, any Node application or any Docker container to a cloud environment where the application is publicly accessible. Depending on resources consumed and […]
Serverless Computing – Function as a Service (FaaS) – with Azure Functions – first small steps with a Node/JavaScript function
If your application does not have internal state – and sometimes it is handling peak loads of requests while at other times it is not doing any work at all, why then should there be one or even more instances of the application (plus container and/or server) continuously and dedicatedly […]
Oracle JET – Filtering Rows in Table with Multiselect and Search Field Filters
A common requirement in any web application: allow the user to quickly drill down to records of interest by specifying relevant filters. The figure overhead shows two way of setting filters: by selecting from the [limited number of] existing values in a certain column – here Location – and by […]
Adding a Cross Instance, Cross Restarts and Cross Application Cache to Node Applications on Oracle Application Container Cloud
In a previous post I described how to do Continuous Integration & Delivery from Oracle Developer Cloud to Oracle Application Container Cloud on simple Node applications: Automating Build and Deployment of Node application in Oracle Developer Cloud to Application Container Cloud. In this post, I am going to extend that […]
Automating Build and Deployment of Node application in Oracle Developer Cloud to Application Container Cloud
A familiar story: Develop a Node application with one or more developers Use Oracle Developer Cloud Service to organize the development work, host the source code and coordinate build jobs and the ensuing deployment Run the Node application on Oracle Application Container Cloud I have read multiple tutorials and blog […]
When Screen Scraping became API calling – Gathering Oracle OpenWorld 2017 Session Catalog with Node
A dataset with all sessions of the upcoming Oracle OpenWorld 2017 conference is nice to have – for experiments and demonstrations with many technologies. The session catalog is exposed at a website – https://events.rainfocus.com/catalog/oracle/oow17/catalogoow17 With searching, filtering and scrolling, all available sessions can be inspected. If data is available in […]
Get going with Node.js, npm and Vue.js 2 on Red Hat & Oracle Linux
A quick and rough guide on getting going with Node, npm and Vue.js 2 on a Enterprise Linux platform (Oracle Linux based on RedHat Linux) Install Node.JS on a Oracle Enterprise Linux system: as root: curl –silent –location https://rpm.nodesource.com/setup_8.x | bash – and: yum -y install nodejs (in order […]
Materials for Workshop Microservices Choreography with Kubernetes, Docker, Kafka and Node.JS
Thursday June 1st – yet another community event at AMIS. This one dedicated to Microservices. What are microservices, why do we think they are interesting? How are they different? How can they be implemented and how do you deploy them? What is a microservices platform and what generic capabilities should […]
Node.js run from GitHub in Generic Docker Container backed by Dockerized Redis Cache
In a previous article I talked about a generic Docker Container Image that can be used to run any Node.js application directly from GitHub or some other Git instance by feeding the Git repo url as Docker run parameter (see https://technology.amis.nl/2017/05/21/running-node-js-applications-from-github-in-generic-docker-container/). In this article, I create a simple Node.js application […]
Running Node.js applications from GitHub in generic Docker Container
This article shows how I create a generic Docker Container Image to run any Node.JS application based on sources for that application on GitHub. The usage of this image is shown in this picture: Any Node.JS application in any public GitHub repo can be run using this Docker Container […]
