Exploring GitHub DockerHub and OCCS Part 3

In my previous post I described how I created a stack definition including my Node.js web application and a MongoDB service using docker-compose. In this article I will describe the steps I took to link my GitHub and Docker Hub accounts in order to automatically build a docker image triggered by a git push command.

Trigger a Build of the MedRec API Docker Image on Docker Hub

Combining internet / cloud based services such as GitHub and Docker Hub allows developers to experience productivity gains without having to fund a local server to provide this capability. I wanted to explore and experience this for myself.

Link Docker Hub and Git Hub accounts

As I didn’t have a docker account for my user I pointed my browser to docker hub … https://hub.docker.com/ and clicked the SignUp option. Continue reading “Exploring GitHub DockerHub and OCCS Part 3”

Exploring GitHub, DockerHub and OCCS Part 2

In my previous post I detailed how I Dockerised the MedRec app. In this post I will show how I added MongoDB and defined a stack using Docker-Compose.

Add MongoDB layer using Docker-Compose

According to the official docker documentation ;

“Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application’s services. Then, using a single command, you create and start all the services from your configuration. ”

A single command to create and start all the services in a configuration sounded pretty good to me. I definitely was keen on exploring docker-compose.

Add a docker-compose.yml file

Having proved that my web application runs up, I now need to address the persistence layer. The above Dockerfile contains the steps to create the required runtime platform for my node app, and installs the node application and package dependences (as specified in the package.json) file by doing the npm install. However if I tried to do a GET or a PUT my app will fail as it won’t find a MongoDB inside my container. I therefore still need a MongoDB somewhere in my environment to hold my application data.

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

Demystifying the Oracle SOA Suite Cloud Service

Recently Carlos and I were given the opportunity to explore the capabilities of the recently released Oracle SOA Cloud Service (SOACS), and to document the steps required to get started with the service.

In this series of blog posts we have put together a record of what we did, and our key takeaways from what we learned during the process in the expectation that it may help others new to the Oracle Public Cloud and specifically the Oracle SOA Suite Cloud Service.
