Docker
A new way of life
What is DOcker?
- Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications.
- Developers can build any app in any language using any toolchain. “Dockerized” apps are completely portable and can run anywhere - colleagues’ OS X and Windows laptops, QA servers running Ubuntu in the cloud, and production data center VMs running Red Hat.
- Sysadmins use Docker to provide standardized environments for their development, QA, and production teams, reducing “works on my machine” finger-pointing.
