What is Docker Value Proposition to Developers?

• Containers: “Build an app once, run it anywhere”

• Tools:“Automate mundane tasks”

• Community: “Collaborate on open source projects”

• Documentation: ”Master the software quickly”

Containers: “Build an app once, run it anywhere”

• Developers want to move applications between development and production environment without worrying about adjusting network or memory settings; they simply want the app to work.

• Example: A lot of companies develop their apps in AWS and then move the container to the production environment in their private cloud.

Containers: “Build an app once, run it anywhere”

Tools: “Automate mundane tasks”

• Docker is the leading container vendor because it comes with a bunch of tools to automate the app creation process.

• Example: According to software engineers I know, Docker became the Linux container of choice due to an unparalleled number of tools supporting app development process.

Tools: “Automate mundane tasks”

Community: “Collaborate on open source projects”

• The Docker product came from a non-threatening source, a small startup (DotCloud) that was able to broadly partner across the whole industry.

• Example: Docker open-sourced their code early on and gained adoption in the DevOps community as well as among established industry players.

Community: “Collaborate on open source projects”

Documentation: “Master the software quickly”

• Developers appreciate the GUI as a quick overview of the system capabilities (What?) but want to access APIs directly from GUI to understand the implementation (How?).

• Example: Developers love Docker documentation website because they get samples of code they can use instantly.

One Container Does Not Solve All Enterprise IT Problems

• LXD: Linux container hypervisor (from Canonical)

• Drawbridge: A Microsoft Research effort to build a library OS micro-service

• AppC: A definition on how to build and run containerized applications (by CoreOS)

• Rocket: CoreOS first implementation of its own AppC specification

• Kurma: Open-sourced containers based on AppC definition (by Apcera)
