  What is Docker? ●Docker is an open-source software platform for building container based applications ( started in 2013 ) ● It carves up a computer into sealed containers that run your code. ● Containers are small and lightweight execution environments that make shared use of the operating system kernel but otherwise run in isolation from one another

  Why Docker? ● Simplicity- Docker’s friendly, CLI-based workflow makes building, sharing, and running containerized applications accessible to developers of all skill levels. ● Agile - Install from a single package to get up and running in minutes. Code and test locally while ensuring consistency between development and production. ● Collaborate -Use Certified and community-provided images in your project. Push to a cloud-based application registry and collaborate with team members.
