One docker container on AWS - resource usage?

If I setup just one Docker container on my AWS - and use only default configuration - would this docker container use the whole memory and all the processors?

Or do I need to configure it?

Memory

There is no memory limit for the container be default, it can use as much as it can.

You can configure the memory usage as below using "-m" flag of docker run command

-m, --memory=""            Memory limit (format: <number><optional unit>, where unit = b, k, m or g)

$docker run -t -i -m 500M centos6_my /bin/bash

Processors

Containers can by default run on any of the available CPUs, CPU usage can be configured using below "-c" and "--cpuset" flag of docker run command

 -c, --cpu-shares=0         CPU shares (relative weight)
  --cpuset=""                CPUs in which to allow execution (0-3, 0,1)

please read Docker documentation for more details : link
