Usually application owner or project owner will specify the quota settings (Memory and CPU) during project creation. But sometimes, they realize that the requested resource is not enough to run their applications.

Usually we name the quota with its specifications and not a good idea to edit this existing quota. Standard practice is to remove/delete the quota for the project and recreate new quota with new values.

Note : You must set quota together with limit.

Check current quota

# oc get quota -n myproject
NAME         AGE
proj-quota-8gi   284d
# oc describe quota proj-quota-8gi -n myproject
Name:           proj-quota-8gi
Namespace:      myproject
Resource        Used    Hard
--------        ----    ----
requests.cpu    4726m   5400m
requests.memory 7000Mi  8Gi

Delete the Quota

WARNING : mention project namespace to avoid any accidental quota delete.

# oc delete quota proj-quota-32gi -n myproject

Create new Quota Template

This is the template file where we mention the memory and CPU quota details.

# cat proj-quota-32Gi_no_limit.yaml
apiVersion: v1
kind: ResourceQuota
metadata:
  creationTimestamp: null
  name: proj-quota-32gi
spec:
  hard:
    requests.cpu: 19200m
    requests.memory: 32Gi

Create new Quota from Template

# oc create -f proj-quota-32Gi_no_limit.yaml -n PROJECT_NAME

Verify new Quota

# oc get quota -n myproject
NAME         AGE
proj-quota-32gi   1d
# oc describe quota proj-quota-32gi -n myproject
Name:           proj-quota-32gi
Namespace:      myproject
Resource        Used    Hard
--------        ----    ----
requests.cpu    5513m   19200m
requests.memory 10724Mi 32Gi
]# oc describe project myproject |grep Quota -A5
Quota:
        Name:           proj-quota-32gi
        Resource        Used    Hard
        --------        ----    ----
        requests.cpu    5513m   19200m
        requests.memory 10724Mi 32Gi

That’s it.
