Resource Quotas

A detailed Resources Quotas dashboard is available for every Project to set quotas that are enforced across all the namespaces within a cluster and all the quotas supported by Kubernetes resource quotas are available. A project would have a default quota per namespace within a cluster which would be propagated to the namespace when it's created on the cluster. The default quotas for all the namespaces (in a cluster) in a Project should not exceed the Project quota. The quotas are actively enforced on the cluster using namespace ResourceQuota.


Resources Quotas Access

Perform the below steps to access the Resource Quotas from the controller:

  • Login to the console and open the Home page
  • Select the required project and click Settings gear icon. An illustrative example is shown below by selecting a project defaultproject

Project Dashboard

General Settings page appears by default.

  • Click Resource Quotas tab to set the namespace quotas
  • Click Configure for the required resource type
  • Provide a Project Limit and Namespace Limit as shown below

Important

Namespace Limit is mandatory when setting the Project Limit and vice-versa

Resource Type Description
CPU Limit The maximum amount of CPU (in millicores) allocated to the project/namespace
CPU Request The minimum amount of CPU (in millicores) guaranteed to the project/namespace
Memory Limit The maximum amount of memory (in bytes) allocated to the project/namespace
Memory Request The minimum amount of memory (in bytes) guaranteed to the project/namespace
Storage Request The minimum amount of storage (in gigabytes) guaranteed to the project/namespace
Services Load Balancers The maximum number of load balancers services that can exist in the project/namespace
Services Node Ports The maximum number of node port services that can exist in the project/namespace
Pods The maximum number of pods that can exist in the project/namespace in a non-terminal state (i.e., pods with a state of .status.phase in (Failed, Succeeded) equal to true)
Services The maximum number of services that can exist in the project/namespace
ConfigMaps The maximum number of ConfigMaps that can exist in the project/namespace
Persistent Volume Claims The maximum number of persistent volume claims that can exist in the project/namespace
Replications Controllers The maximum number of replication controllers that can exist in the project/namespace
Secrets The maximum number of secrets that can exist in the project/namespace

Important

Project Limit must always be higher than the Namespace Limit. Configmaps and Secrets are utilized for various purposes internally in the Kubernetes lifecycle, thus configuring low quotas for configmaps or secrets might prevent regular operations (e.g., workload deployments on the clusters). To avoid such blockages, set the project limit to 100 or more for these two resource types

Project Dashboard

  • Click Save to set the configuration

Once the quotas are successfully set, these limits are automatically applied to the clusters deployed in that specific project

Utilizations

Utilizations page shows the quota details used for the resource at the time of namespace creation and remaining quota limit.

  • Click Utilizations

Project Dashboard

  • Utilization page appears with the details on Resource Type, Project Limit, Namespace Limit, and Utilizations
