Project Quotas

KubeSphere uses Kubernetes requests and limits to control resource (for example, CPU and memory) usage in a project, also known as ResourceQuotas in Kubernetes. Requests make sure a project can get the resources it needs as they are specifically guaranteed and reserved. On the contrary, limits ensure that a project can never use resources above a certain value.

Besides CPU and memory, you can also set resource quotas for other objects separately such as Pods, Deployments, Jobs, Services and ConfigMaps in a project.

This tutorial demonstrates how to configure quotas for a project.

Prerequisites

You have an available workspace, a project and an account (ws-admin). The account must have the admin role at the workspace level. For more information, see Create Workspaces, Projects, Accounts and Roles.

Note

If you use the account project-admin (an account of the admin role at the project level), you can set project quotas as well for a new project (i.e. its quotas remain unset). However, project-admin cannot change project quotas once they are set. Generally, it is the responsibility of ws-admin to set limits and requests for a project. project-admin is responsible for setting limit ranges for containers in a project.

Set Project Quotas

Log in to the console as ws-admin and go to a project. On the Overview page, you can see project quotas remain unset if the project is newly created. Click Set to configure quotas.
In the dialog that appears, you can see that KubeSphere does not set any requests or limits for a project by default. To set requests and limits to control CPU and memory resources, use the slider to move to a desired value or input numbers directly. Leaving a field blank means you do not set any requests or limits.

Note

The limit can never be lower than the request.
To set quotas for other resources, click Add quota item and select an object from the list.
Click OK to finish setting quotas.
Go to Basic Info in Project Settings, and you can see all resource quotas for the project.
To change project quotas, click Manage Project on the Basic Info page and select Edit Quota.
Change project quotas directly on the Project Quota page and click OK.
