Applying allocation rules for a space

To ensure optimal utilization of infrastructure resources, the minimum and maximum values required for the applications can be configured.

Follow the steps below to configure assignment rules:

  1. Navigate and locate to Manage → Spaces

  2. Select the Space for which you want to configure the allocation rules

    Space overview page

  3. Select the corresponding tab Allocation Rules in the upper part of the Spaces detail view.

  4. In the Allocation Roles view, on the left side, you will find a table list where you can set the allocation rules individually for each cluster present in this namespace.
    Here you can configure the maximum, limit, requirements, and minimum of the central processing unit (CPU), memory, storage, and maximum allowed pods in the namespace.

Resource quota

Allocation Role

Description

CPU Max

Configure the maximum allowed CPU usage of the individual pod in the namespace.

CPU Min

Configure minimum CPU limit that the pod can use in this namespace.

Memory Max

Configure the maximum Memory the pod can use.

Memory Min

Set the minimum memory request limit for the pod.

Pod Max

Set the amount of how many pods can be provisioned in this cluster.

Storage Max

Define the storage maximum limit.

Default resources for containers

Allocation Role

Description

CPU Limit

Limit the pod CPU requests by setting a hard ceiling that the pod can use.

CPU Request

Configure CPU request threshold that the pod can request in this namespace.

Memory Limit

Configure the hard ceiling for the memory request of the pod.

Memory Request

Configure the request size of the memory for the pod.

Measuring units CPU

Limits and requests for CPU resources are measured in CPU units. One CPU unit corresponds to 1 physical CPU core or 1 virtual core, depending on whether the node is a physical host or a virtual machine running within a physical machine.

Measuring units Memory

Memory limits and requirements are measured in bytes. You can specify the memory as an integer or as a fixed-point number with one of the following suffixes: E, P, T, G, M, k. You can also use powers of two: Ei, Pi, Ti, Gi, Mi, Ki.

For example, the following numbers represent approximately the same value:

  • 128974848, 129e6, 129M, 128974848000m, 123Mi
