Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. It allows applications to be assembled from components and run unchanged on laptops, data centers, and clouds. Containers provide isolation at the OS level and share resources to provide lightweight virtualization compared to virtual machines. Docker standardizes the container format and tools to make containers portable and easy for developers to use, improving the development lifecycle.

- 2. Cargo Transport 1960s The Problem
- 3. Solution? The Solution? Intermodal Shipping Container
- 4. 90% of all cargo now shipped in a standard container Order of magnitude reduction in cost and time to load and unload ships, trains, trucks The Solution?
- 8. So now what’s Docker? The Docker Solution About Docker Inc. • Founded in 2009. • Formerly dotCloud Inc. • Primary sponsor of the Docker Project. • Hires maintainers and contributors. • Provides infrastructure for the project. • Runs the Docker Hub. • HQ in San Francisco. • Backed by more than 100M in venture capital.
- 9. So now what’s Docker? The Docker Solution Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.” source: https://www.docker.com/whatisdocker/
- 10. containers as lightweight VMs The Docker Solution
- 11. Virtual Machine and Container Complement each other The Docker Solution Containers ● Containers run as isolated processes in user space of host OS ● They share the kernel with other container (container-processes) ● Containers include the application and all of its dependencies ● Not tied to specific infrastructure Virtual Machine ● Virtual machines include the application, the necessary binaries and libraries, and an entire guest operating system ● Each Guest OS has its own Kernel and user space
- 12. Containers before Docker The Docker Solution ● No standardized exchange format. (No, a rootfs tarball is not a format!) ● Containers are hard to use for developers. (Where's the equivalent of docker run debian?) ● No re-usable components, APIs, tools. (At best: VM abstractions, e.g. libvirt.) Analogy: ● Shipping containers are not just steel boxes. ● They are steel boxes that are a standard size, with the same hooks and holes
- 13. Containers after Docker The Docker Solution ● Standardize the container format, because containers were not portable. ● Make containers easy to use for developers. ● Emphasis on re-usable components, APIs, ecosystem of standard tools. ● Improvement over ad-hoc, in-house, specific tools.
- 14. Docker Benefit The Docker Solution Make the entire lifecycle more efficient, consistent, and repeatable Increase the quality of code produced by developers Eliminate inconsistencies between development, test, production, and customer environments Support segregation of duties Significantly improves the speed and reliability of continuous deployment and continuous integration systems Because the containers are so lightweight, address significant performance, costs, deployment, and portability issues normally associated with VMs
- 15. Container image as build artifact The Docker Solution
- 16. The Docker Solution Developer Say: Build Once, Run Anywhere Operator: Configure Once, Run Anything
- 17. Docker Architecture The Docker Solution
- 18. Lifecycle of a docker container The Docker Solution
