What is the interaction of Docker's CpuShares between containers?
If we have 3 Docker containers running a 4 vcpu AWS instance and two containers say “CpuShares:0” and the third container says “CpuShares:2” how does that work?
Does the “CpuShares:2” container have access to 2 or all 4 cpus? What does “CpuShares:0” mean?. Does the “CpuShares:2” container basically just get priority over the other containers?
