Configure a Limit Range

Set default CPU and memory requests/limits, as well as minimum and maximum values, for containers and Pods within a namespace.

Prerequisites

• Cluster administrator or namespace management permissions are required.
• The target namespace must exist.

INFO

Limit Ranges only apply to newly created containers. Existing Pods are not affected.

---

Step 1. Open the Create Limit Range form

Select Policy → Limit ranges from the left sidebar. Click the Create limit range button in the top right.

---

Step 2. Enter basic information

Field	Description	Example
Name	Limit Range name	container-limits
Namespace	Target namespace	default

---

Step 3. Configure Container limits

Select the Container tab and enter the default values and ranges.

Field	Description	Example
Default Request CPU	Auto-applied CPU request on Pod creation	100m
Default Limit CPU	Auto-applied CPU limit on Pod creation	500m
Min CPU	Minimum allowed CPU request	50m
Max CPU	Maximum allowed CPU limit	2
Default Request Memory	Auto-applied memory request	128Mi
Default Limit Memory	Auto-applied memory limit	512Mi
Min Memory	Minimum allowed memory	64Mi
Max Memory	Maximum allowed memory	1Gi

TIP

Setting Default Request and Default Limit automatically applies those values to containers that do not specify resource requirements. Especially useful when combined with a Resource Quota.

---

Step 4. Confirm creation

Click Create. Verify the created entry in the Limit ranges list.

New containers created in this namespace will automatically receive the default values.
