The Scheduler that decides which node a part goes to.
The scheduler takes into consideration the amount of resources required by a part and those available
on the nodes.
By default Kubernetes assumes that a port or a container
within a port requires point five CPU and 256 megabyte of memory.
This is known as the resource request for a container, the minimum amount of CPU or memory requested
by the container when the scheduler tries to place the port on a note.
It uses these numbers to identify a node which has sufficient amount of resources available.
Point to Note
A container cannot use more CPU resources than its limit.
However, this is not the case with the memory.
A container can use more memory resources than its limit.
