Hi Vinay,
I've been curious about Docker. I can't figure out if Docker is not Virtual Machine, then why it needs Hyper-visor to run ? Hyper-v is a virtual machine supporting hardware, isn't it ?


Docker doesn't need hypervisor to run but relies on the Host OS for its functionality.

This is because Docker Containers consist of only essential binaries & dependencies to be executed.

By that definition, many containers of the same application can share the same OS kernel & run independently.

Hypervisor is an interface used by VM OSes to work with hardware.

Hoping this helps!
