Introducing Docker
What is Docker?
“Docker is an open platform for developers and system admins to
build, ship, and run distributed applications.”
How is this different from Virtual Machines?
“Docker runs as an isolated process in userspace on the host
operating system, sharing the kernel with other containers. Thus, it
enjoys the resource isolation and allocation benefits of VMs but is
much more portable and efficient. ”

8. ROME 27-28 march 2015 - Giulio Santoli
• Image – layered file system where each layer references the layer below
• Container – runtime instance of an image plus a read/write layer
• Dockerfile – build script that defines:
– an existing image as the starting point
– a set of instructions to augment that image (each of which results in
a new layer in the file system)
– meta-data such as the ports exposed
– the command to execute when the image is run
• Docker Hub – centralised repository of Docker images
