Docker is a kind of virtualization in which we wrap up the whole development environment in an entity which is defined as a container so that we can overcome the problem of application portability and can run our application on any kind of platform.
It helps us to bind the code, system tools, and system libraries inside a container and therefore makes it easy for developers and system admins to focus only on their own work.
Dockers are in use to deploy applications in one go and don’t require any complexity on any platform.
Containers are lightweight and can share the kernel and file system of the same operating system if deployed on a single system.
However, containers are in isolation from each other, and in that way, they provide an extra layer of security to the application.
With the help of containers we can run multiple versions of a specific service on a single server for example you can run mysql-5.5 and mysql-5.6 both on a single server efficiently. We can connect multiple containers to each other to fulfill the complex architecture of an application.
