Solution: Intermodal Shipping Container

…in between, can be loaded and unloaded, stacked, transported efficiently over long distances, and transferred from one mode of transport to another

A standard container that is loaded with virtually any goods, and stays sealed until it reaches final delivery.

An engine that enables any payload to be encapsulated as a lightweight, portable, self-sufficient container…

Why it works — separation of concerns

Oscar the Ops Guy

Worries about what’s “outside” the container• Logging• Remote access• Monitoring• Network config

All containers start, stop, copy, attach, migrate, etc. the same way

Dan the Developer

Worries about what’s “inside” the container• His code• His Libraries• His Package Manager• His Apps• His Data

All Linux servers look the same

Docker ContainersA technical view into the shared and layered file systems technology

Docker uses a copy-on-write (union) filesystemNew files(& edits) are only visible to current/above layers

Layers allow for highly-efficient reuseMore containers per host – higher overall server utilizationFaster start-up/download time – base layers are "cached"

Docker Delivers Innovation, Speed and Savings

Deploys 1,500X a week

“Docker gives us more speed and speed for us is a huge measure of our transformation. Getting value to the customers faster, that’s where Docker helps us.”

CI jobs run over 60% faster

“Docker is a natural fit for us. We wanted testing environments that

we could change easily and Docker handles this for us”

Ships 100X a day

“I love Docker. It’s simple for developers and it works for ops.

There is a really positive emotional connection that

Docker has created with our developer community “
