Service CPU Resources
In the field CPU Resources, you have to specify:
- Request: the minimum number of "thousandth of a core" (m) that the container needs (in Kubernetes it's the request).
- Limit: the maximum number of "thousandth of a core" (m) that it can use (in Kubernetes it's the limit).
To learn more about the meaning of these values inside Kubernetes, please visit this page in the Kubernetes documentation.
CPU resources are measured in CPU units. One CPU, in Kubernetes, is equivalent to:
1 AWS vCPU;
1 GCP Core;
1 Azure vCore;
1 Hyperthread on a bare-metal Intel processor with Hyperthreading.
CPU Resources, which are measured in CPU units, can be expressed as an integer or a fractional value with one of these suffixes: m and milli.
The different suffixes, applied to different integers or fractional values, can express the same CPU Resource value. For example: 100m CPU, 100 milliCPU, and 0.1 CPU are all the same.
It is not possible to be more precise than 1m and CPU is a always an absolute quantity. For example, 0.1 is the same amount of CPU on a single-core, dual-core, or 48-core machine.
In the microservice detail of Mia-Platform Console, you can only express the CPU Resource value in m.
You can use interpolated variables to value the CPU resources (e.g. {{CPU_MIN}}). The variables should contain only numerical values.
The check about that Limit have to be greater than Request won't be done if you use interpolated variables.
