# What is Docker?
|
||
|
||
Docker is an open-source project that automates the deployment of applications
|
||
inside software containers, by providing an additional layer of abstraction and
|
||
automation of operating system–level virtualization on Linux. Docker uses
|
||
resource isolation features of the Linux kernel such as cgroups and kernel
|
||
namespaces to allow independent "containers" to run within a single Linux
|
||
instance, avoiding the overhead of starting virtual machines.
