4.2. Resource quotas across multiple projects

Procedure

1. To select projects based on annotations, run the following command:

   $ oc create clusterquota for-user \
        --project-annotation-selector openshift.io/requester=<user_name> \
        --hard pods=10 \
        --hard secrets=20

   This creates the following ClusterResourceQuota object:

   apiVersion: v1
   kind: ClusterResourceQuota
   metadata:
     name: for-user
   spec:
     quota: 

   1

   
       hard:
         pods: "10"
         secrets: "20"
     selector:
       annotations: 

   2

   
         openshift.io/requester: <user_name>
       labels: null 

   3

   
   status:
     namespaces: 

   4

   
     - namespace: ns-one
       status:
         hard:
           pods: "10"
           secrets: "20"
         used:
           pods: "1"
           secrets: "9"
     total: 

   5

   
       hard:
         pods: "10"
         secrets: "20"
       used:
         pods: "1"
         secrets: "9"

   1

   The ResourceQuotaSpec object that will be enforced over the selected projects.

   2

   A simple key-value selector for annotations.

   3

   A label selector that can be used to select projects.

   4

   A per-namespace map that describes current quota usage in each selected project.

   5

   The aggregate usage across all selected projects.

   This multi-project quota document controls all projects requested by <user_name> using the default project request endpoint. You are limited to 10 pods and 20 secrets.

2. Similarly, to select projects based on labels, run this command:

   $  oc create clusterresourcequota for-name \

   1

   
       --project-label-selector=name=frontend \

   2

   
       --hard=pods=10 --hard=secrets=20

   Both clusterresourcequota and clusterquota are aliases of the same command. for-name is the name of the ClusterResourceQuota object.

   2

   To select projects by label, provide a key-value pair by using the format --project-label-selector=key=value.

   This creates the following ClusterResourceQuota object definition:

   apiVersion: v1
   kind: ClusterResourceQuota
   metadata:
     creationTimestamp: null
     name: for-name
   spec:
     quota:
       hard:
         pods: "10"
         secrets: "20"
     selector:
       annotations: null
       labels:
         matchLabels:
           name: frontend
