Add a metrics endpoint for Prometheus

[mms-gianni]

It would be nice to have a possibility to see how many apps are running and what the status is.

I like the idea of prometheus-queryable metrics for apps and pipelines.

Have you considered using kube state metrics for basic monitoring of custom resources and their state?
If the first step in monitoring kubero is just "What is running an what is the status" it'd be pretty simple to list all kuberoapps and their status (via the Status field).

I'll setup an example in the next few days and share my config if you are interested in this approach.

I had a closer look into kube_state_metrics. Very cool project I was not aware of yet. It provides a ton of metrics.

Looking forward on your approach .
