Learn 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).
The hands-on lab is designed to help you get a taste for how you can use Docker to simplify application provisioning on Linux. It demonstrates how to create a Docker container on Oracle Linux, modify it, and use it to instantiate multiple application instances. It also describes how to allocate system CPU and memory resources to a Docker container, how to set up a database container, and how other containers can connect to that database container.
You can find the hands-on lab on the Oracle OTN site.
