01/18/2023, 4:42 PMI read that K3s doesn’t recommend using namespaces,Yeah, what are you reading? We don’t say that and I’m not sure why anyone else would.
The Metric server comes with k3s has support for monitoring/alerting?No, it does not do alerting. You can read about the metrics-server at https://github.com/kubernetes-sigs/metrics-server - but it is pretty much only used for
kubectl top pods
and kubectl top nodes
as well as some of the cluster autoscalers if you deploy them. If you want long-term monitoring and alerting you would be looking at deploying prometheus and grafana or something along those lines.handsome-autumn-77266

means you have asked for no instances of the pod (the app, in the case you are describing) running. Nothing running.
replicas: 1
means you have asked for one copy of your app running
replicas: 2
means you have asked for two copies of your app running
There is no "original" and "replicas" - they are all replicas and they are all treated with the same respect.
I think the docs on ReplicSets should help - and remember that a Deployment makes a replica set.handsome-autumn-77266
