使用 --cpus=<value> 命令，在 docker run的时候进行分配，
If you have 1 CPU, each of the following commands guarantees the container at most 50% of the CPU every second.
Docker 1.13 and higher:
docker run -it --cpus=".5" ubuntu /bin/bashDocker 1.12 and lower:
$ docker run -it --cpu-period=100000 --cpu-quota=50000 ubuntu /bin/bash更多的参数可以参考：
Limit a container's resources

这是命令行参数，yml中怎么写？

@dudu:
In this general example, the redis service is constrained to use no more than 50M of memory and 0.50 (50%) of available processing time (CPU), and has 20M of memory and 0.25 CPU time reserved (as always available to it).
