Exploring GitHub Docker Hub and OCCS Part 1

In my previous post in this series I provided an Introduction describing the high level steps I planned to take.
In this post I will walk through the detailed steps to Dockerise the MedRec application.

Dockerise the MedRec APIs

Git clone the project repository

I used my Windows Surface Pro-4 with Oracle VM Virtual Box installed to host my development VM. I managed to source a VBox image that already had Ubuntu 16.04 and Docker installed so that helped get me started. In my development environment on my laptop, I created a directory under my home directory named gitprojects.
I cd into that directory.

cd gitprojects

Exploring GitHub, DockerHub and OCCS – Introduction

As part of our MedRec API playpen initiative we had already developed some REST API’s using Node.js and leveraged MongoDB running on Oracle IaaS as the persistence layer. . This post describes what I did to dockerise the MedRec API application and eventually run it on the Oracle Container Cloud Service (OCCS).

The APIs have already been made available for interested parties to interact with via SwaggerUI. Of course developers could develop their own code (or any REST client) to interact with them. As a team we used a combination of the Oracle Developer Cloud Service (Git repository, Issue Tracker, Build Server etc) and also the public GitHub to provide public access to our project code. As the source code for the Node.js project containing the API’s was pushed to GitHub I simply did a clone of the Node application code in order to download and run it locally (MedRec API tutorials available here).

The application ran well enough on my local laptop which running Ubuntu 16.04, however I really wanted to be able to try to run the app and MongoDB as a Docker image/stack on my laptop. After I had the application successfully “Dockerised”, then I planned to deploy my application stack to the Oracle Container Cloud Service. I also wanted to explore the use of the GitHub / Docker Hub integration to build my image on Docker Hub, and then from within the Oracle Container Cloud Service (OCCS). With the application image available on Docker Hub, I could then pull my image from that source in order to run it up on OCCS.

A good blog can really help bring you up to speed quickly and help overcome inertia to get you started and I would like to acknowledge the help that Mauricio Payetta’s blog provided me.

In this series of blog posts I plan to retrace what I did during my self-learning. Continue reading “Exploring GitHub, DockerHub and OCCS – Introduction”

Building a Docker Image for WebLogic 12.2.1.2 MedRec app

This blog walks you through the steps I used to get WebLogic Server and the MedRec sample application installed into a Docker image. There are many well documented GitHub projects for the Oracle Docker Images. This blog is meant to simply narrow down exactly what I did to get this going in my environment. I was using Ubuntu 16.04, and already had Docker installed.

First Experience Using SOACS – Integration Analytics

The Integration Analytics Service Type (Insight) includes Real-Time Integration Business Insight and Business Activity Monitoring. Insight allows a user to easily define business milestones, map data from existing Oracle SOA and Service Bus projects. Insight also provides an OOTB Dashboard to surface milestone status as well as providing a capability for a user to build a custom dashboard. It also exposes an Event REST API which allows a developer to POST a JSON payload to the API in order to update the Milestone Dashboard.

In my previous blog on Integration Analytics I walked through the steps required to provision the Integration Analytics Cloud Service. In this blog I want to show how easy it is to invoke the service using the exposed REST API, and create milestones that are visible in the Out of the Box Dashboard. My manager is always telling me to take an MVP ( Minimum Viable Product) approach to things I am learning so I am deliberately attempting to be as (smart) lazy as possible. If there is an existing capability that helps me to rapidly reach my end goa, then I plan to use it. Bottom line, with Integration Analytics there is a lot more I could mention but I am focussed on just getting a REST call to work against the service that I just provisioned.

First Experience Provisioning SOACS – Integration Analytics

Oracle introduced the Real Time Integration Business Insight product as part of its Integration offering in 2016. For a 2 minute overview check out Insight Overview Video .

The good news is that this capability is now available in the Oracle Public Cloud as part of the SOA Cloud Service and can be provisioned using the Integration Analytics Cluster service type.

In this blog I plan to do the following;

  • Briefly introduce Integration Analytics and Real Time Integration Business Insight (Insight)
  • Walk through the Provisioning Steps
  • Walk through the Post Provisioning Steps

In a related blog post I will cover how to interact with the Integration Analytics capability via REST.

First experience Using the Oracle Container Cloud Service

In a previous blog on OCCS, I covered the steps required to provision the service. As an input to the OCCS Service provisioning I was prompted to specify the number of worker nodes I required, which for my example I set to be two. Having provisioned the service, I can now start to build and run my Docker images on these worker nodes. As part of the provisioned service, I have a node dedicated to the Container Console which provides a nice web User Interface that allows me to Build, Deploy, Run and Manage Docker Containers on the worker node hosts that I provisioned as part of my service. The two worker nodes are the hosts that I will ultimately deploy and running the image of interest such as WordPress, MySQL, Oracle Database, Tomcat, Nginx, WebLogic Server or whatever you want pretty much. The Container Console makes it very easy to build, run and deploy images via a web administration console.

First experience – Provisioning the Oracle Container Cloud Service

In December 2015, Oracle acquired the StackEngine, which provided (Docker) container management software and automation (DevOps) capabilities. According to Wikipedia, https://en.wikipedia.org/wiki/StackEngine – “The StackEngine model-based Docker management software provided an integrated DevOps solution for end-to-end container application delivery and operation, all with an integrated GUI dashboard, service discovery, scheduling, and orchestration functions. StackEngine could be deployed into any on-premise, hybrid, public, or private cloud environments and scaled across thousands of hosts enabling users to start in the lab and scale out to full production.”

In November 2016, Oracle announced the general availability of the Oracle Container Cloud Service (OCCS) which had taken the StackEngine capabilities and transformed them into a Cloud Service.
