Install Docker CE on CentOS 7
What is Docker?
Docker is an open source platform that enables developers to build, deploy, run, update and manage containers—standardized, executable components that combine application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.. As written here, Docker Community Edition (CE) is ideal for developers and small teams looking to get started with Docker and experimenting with container-based apps. Docker CE has two update channels, stable and edge:
- Stable gives you reliable updates every quarter.
- Edge gives you new features every month.
