workflow-count-resourcequota.yaml

apiVersion: v1
kind: ResourceQuota
metadata:
  name: workflow-count
  annotations:
    workflows.argoproj.io/description: |
      This resource quota prevents creation of more than a certain number of workflows being created in a namespace.

      The user will get an error when they try to create more. As the count includes both completed and incomplete
      workflows, and complete workflows do not make any significant demands of your cluster, you probably want to use it
      with a workflow GC strategy, so that a build up of completed workflows does not prevent you from creating and
      running new workflows.

      Argo Workflowws has feature called "parallelism" that limits the number of running workflows, ignoring completed
      workflows.

      <= v3.1 you can configure a global limit to the total number of running workflows in the cluster. This is suitable
      for single-tenancy set-up.

      For multi-tenancy set-up, where each tenant own a single namespace, then in >= v3.1 you can globaly configure a
      limit for the total number of running workflows within each namespace.
