How to create a SOA 12.2.1 docker image on OracleLinux (Now Oracle Certified) by Fabio Persico




What is docker?

Unless you’ve been living without internet access for the last two years, it would be hard not to at least heard of Docker. But, as an emerging technology not everyone has taken the time to work out what Docker is, where it fits in and how it can benefit you.
So, what exactly is Docker? Here’s what Docker themselves describe it as:
Docker is an open platform for developers and sysadmins of distributed applications.
Essentially, Docker is a container based system for your applications. If you’re used to the concept of virtual servers, Docker provides further levels of abstraction for your application. Here’s a visual representation of how it differs:

Rather than just being one part of the puzzle, Docker provides a number of components and tools to assist with the entire lifecycle management of the application. This includes the container environment, image management and orchestration.
Docker started it’s life as an internal project within a hosting company called dotCloud, but quickly took off once they open sourced it in early 2013. Since then, it’s benefited from over 15,000 software commits from over 900 contributors.
