Pod Specifications

If the pod type is not GPU-accelerated, the pod specifications you select must meet the following requirements:

The total number of CPU cores in a pod can be a value in the range of 0.25-32, 48, or 64. The total number of CPU cores in a container is an integer multiple of 0.25.
The total memory size (in GB) of a pod is an integer from 1 to 512.
The ratio of CPU cores to memory size in a pod ranges from 1:2 to 1:8.
A pod supports a maximum of five containers. The minimum configuration of a container is 0.25 cores and 0.2 GB. The maximum configuration of a container is the same as that of the pod.
The request of an application container or init container in a pod equals to the limit of that container.

For details, see Pod Specification Calculation.

Pod Storage Space

If no EVS disk or other cloud storage is mounted, the application data is stored in the physical disks of the container. Each pod can be allocated with a maximum of 20 GB disk space (both the CPU host and the GPU host).

Quotas

CCI imposes a quota on the number and capacity of resources that can be used by a user. For details, see Quotas.

Pod Specification Calculation

The pod specifications are calculated based on the following rules:

The highest of any particular resource request or limit defined on all init containers in the pod is the effective init request/limit.
The pod's effective request/limit for a resource is the higher of:
- the sum of all application containers request/limit for a resource
- the effective init request/limit for a resource
