Meaning of memory
128974848, 129e6, 129M, 123Mi
123Mi = 123 1024 1024 = 128,974,848 Bytes
129M = 129 1000 1000 = 129,000,000 Bytes
举例说明：
当我们在Deployment设置memory = 500Mi时候，在Kubernetes显示使用内存 524.29 MB = (500Mi 1024 1024) / 1000 / 1000 = 524.288 MB
Meaning of CPU
Limits and requests for CPU resources are measured in cpu units. One cpu, in Kubernetes, is equivalent to:
- 1 AWS vCPU
- 1 GCP Core
- 1 Azure vCore
- 1 IBM vCPU
- 1 Hyperthread on a bare-metal Intel processor with Hyperthreading
A request with a decimal point, like 0.1, is converted to 100m by the API.

ReplicationController
A ReplicationController ensures that a specified number of pod replicas are running at any one time. In other words, a ReplicationController makes sure that a pod or a homogeneous set of pods is always up and available.
