Docker I

Thursday, 1:30 PM

“Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.” Docker creates containers that provide running process with:

  • an equal slice of CPU
  • a maximum memory quota
  • its own process ID (PID) namespace
  • its own network interface
  • its own private root filesystem

It does this by leveraging low-level Linux kernel primitives like cgroups and namepaces. The end result is a portable application container that can run anywhere Docker can run, including on VMs, bare-metal servers, OpenStack clusters, public instances, or combinations of the above.

Containers are an excellent way to package your application such that it can run consistently everywhere you want to run it, a fantastic step toward Continuous Delivery. In this session we’ll look at how to use Docker to package, deploy, and run Java applications and other services. We’ll also compare Docker to another container solution, Warden, which is a key component of the Cloud Foundry PaaS.
