As Ginny Henningsen puts it, "Docker is an open source virtualization technology that creates lightweight Linux application containers." What I think is particularly cool about Docker is the portability it derives from its open-source genes. As Ginny explains:
"Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud."
Here's her article, plus a few additional resources to help you include Docker in your Linux deployments:
Tech Article: Getting Started with Docker on Oracle Linux

How to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers).

I took the picture of that wagon in Stovepipe Wells, Death Valley, on my ride to the Sun Reunion.
P.S. My last day at Oracle will be May 31. If you'd like to stay in touch, use the links on the left, below:
