kubernetes - Unable to create namespace quota using helm

Question

I am facing the following issue related specifying namespace quota.

1. namespace quota specified is not getting created via helm. My file namspacequota.yaml is as shown below

apiVersion: v1
kind: ResourceQuota
metadata:
  name: namespacequota
  namespace: {{ .Release.Namespace }}
spec:
  hard:
    requests.cpu: "3"
    requests.memory: 10Gi
    limits.cpu: "6"
    limits.memory: 12Gi

Below command used for installation

helm install privachart3 . -n test-1

However the resourcequota is not getting created.

kubectl get resourcequota -n test-1
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
NAME                  CREATED AT
gke-resource-quotas   2021-01-20T06:14:16Z

2. I can define the resource-quota using the below kubectl command.

kubectl apply -f namespacequota.yaml --namespace=test-1

The only change required in the file above is commenting of line number-5 that consist of release-name.

kubectl get resourcequota -n test-1
NAME                   CREATED AT
gke-resource-quotas    2021-01-20T06:14:16Z
namespacequota         2021-01-23T07:30:27Z

However in this case, when i am trying to install the chart, the PVC is created, but the POD is not getting created.

The capacity is not an issue as i am just trying to create a single maria-db pod using "Deployment".

Command used for install given below

helm install chart3 . -n test-1

Output observed given below

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
NAME: chart3
LAST DEPLOYED: Sat Jan 23 08:38:50 2021
NAMESPACE: test-1
STATUS: deployed
REVISION: 1
TEST SUITE: None

Answer 1

I got the answer from another the Git forum. Upon setting a namespace quota we need to explicitly set the POD's resource. In my case i just needed to specify the resource limit under the image.

  - image: wordpress:4.8-apache
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"

Post that i am now able to observe the PODs as well
