I have deployments consuming different RabbitMQ queues. Each deployment has a different HPA tied to the queue metrics with different scaling formulas. All of this works well. The pods write into a DB and I would like to have the total number of pods for all deployments limited to a number to avoid…

yes, trying to coordinate HPA scaling through metric manipulation isn’t the ideal approach. you can try creating a custom controller that: try monitoring all your deployments Calculates the total pods across all deployments try adjusting individual HPA maxReplicas

Hi, @RenardDesMers , one of the options for limiting total number of pods of all deployments would be setting ResourceQuota. Put all your consuming app deployments in a single namespace and set and a hard limit of pods number: apiVersion: v1 kind: ResourceQuota metadata: name: simple-quota nam…
