Microservices PoC: Docker Calculator build with docker-compose

Hopefully you have been following my Docker exploits allowing me to share as I go along. Recently I posted a part two on my Microservices PoC describing a simple calculator. The solution currently instructs to you to execute four (4) docker build commands to create the individual containers for the calculator function. When I did …

Microservices PoC: A Docker Calculator Pt.2

In my previous Microservices PoC post, I attempted to use a calculator to conceptualize microservices. The premise was to look at the calculator as a monolithic application and then break it down into discrete services. The focus was on the Add, Subtract, Multiply, and Divide functions and deploying them in separate docker containers thus creating …

Install SQL Developer on Ubuntu 17.04

Last week I decided to blow away Windows on my ASUS laptop and install a flavor of #Linux. I’ve got a few machines running Oracle Linux so I settled on #Ubuntu. To be more specific: dbryant@asus:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 17.04 Release: 17.04 Codename: zesty As a …

Microservices PoC: A Docker Calculator

This example will explore building a simple container that has one specific ¬†function. I’ll then extend this concept to a bit to add additional containers in an effort to build a basic calculator that can add, subtract, divide, and multiply. The current rendition will execute from the command line. Given enough time, we can REST …

I started looking at MongoDB, and over the last couple of weeks, I’ve found it to be quite fun. This post will focus on my intro to MongoDB and hopefully will result in a …

Deploy node-oracledb with Official Instant Client Image

A few days ago, I started building a PoC with the Oracle DB 12.1 and Oracle Instant Client. My goal was to deploy each component to separate and see if I could access the DB from the OIC container. Now to take it a step further. Adding the node-oracledb driver to enable Node.js interaction with …

Clean up qcow2 in Docker on MacBook

I really enjoy figuring out stuff to do with DOCKER, but I recently tweeted the following: Why you ask? Well, there is this file, Docker.qcow2 located right here: ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2 on my MacBook Pro that consumes all of the remaining space I have on my hard drive, and SSD’s ain’t cheap. ¬†I’m sure I need to …

Using the Oracle Instant Client with Docker and Oracle DB12c

This weekend, in my desire to learn more about Docker, I decided to implement a multi-container solution. In this PoC, I plan to deploy a container with the Oracle Database 12.1 and a second container with the Oracle Instant Client 12.2. The goal will be to connect to the Database container from the Instant Client …

SSH Into the Oracle Database Cloud Service

One of the things that make us feel comfortable when working with a database is the ability to ssh into the server, connect to the database, and use sqlplus or sqlcl to interact with the database. You might not know it, but even though the Oracle Database Cloud Service is a PaaS solution, you still …
