This Kubernetes cronjob is able to detect low quota values for Cloud Providers defined in Red Hat Advanced Cluster Management.

1. GCP
2. Azure

The code checks every 60min for quota values across all cloud providers on the system. It generates Kubernetes Warning events in the namespaces where the Cloud Provider secrets are stored. It also associates the event to the Cloud provider secret.

It is as simple as connecting to OpenShift hosting Advanced Cluster Management and running the following command:

# Log into Openshift
make setup

You can view the status of the cronjob:

oc get cronjobs -A

Use the OpenShift event view to see output. Filter on quota

Command:

make runqc

Check the output:

oc get pods | grep cloudprovider-quotacheck-job
oc logs <POD_NAME_FROM_PREVIOUS_COMMAND>

Update:

./deploy/cloudproviderquotacheck-cronjob.yaml
./deploy/cloudproviderquotacheck-job.yaml

Change the env variable CM_THRESHOLD

env:
- name: PYTHONWARNINGS
    value: "ignore:Unverified HTTPS request"
- name: CM_THRESHOLD
    value: "85"             # This is the threshold percentage after which a kube warning event is fired

export CM_TOKEN=<TOKEN_VALUE>                  # The OCP connection token
export CM_API_URL=https://my.cluster.com:6443  # The OCP API URL

# OPTIONL
export CM_THRESHOLD=85                         # The threshold above which a kube warning event is fired

# Required to BUILD & PUSH
export tag=0.X                   # Used to tag the image
export REPO_URL=quay.io/my-repo  # Repository to push image. requires docker already be authenticated

export NAMESPACE         # Used to work with a different namespace

Also edit deploy/rolebinding.yaml file and replace open-cluster-management with yournamespace of choice
