instruction: Create a Dockerfile for fundamentals

  from the default. For most use-cases, --cpus is a more convenient alternative.--cpu-quota=<value>Impose a CPU CFS quota on the container. The number of microseconds per --cpu-period that the container is limited to before being throttled. As such acting as the effective ceiling. For most use-cases, --cpus is a more convenient alternative.--cpuset-cpusLimit the specific CPUs or cores a container can use. A comma-separated list or hyphen-separated range of CPUs a container can use, if you have more than one CPU. The first CPU is numbered 0. A valid value might be 0-3 (to use the first, second, third, and fourth CPU) or 1,3 (to use the second and fourth CPU).--cpu-sharesSet this flag to a value greater or less than the default of 1024 to increase or reduce the container's weight, and give it access to a greater or lesser proportion of the host machine's CPU cycles. This is only enforced when CPU cycles are constrained. When plenty of CPU cycles are available, all containers use as much CPU as they need. In that way, this is a soft limit. --cpu-shares doesn't prevent containers
