It seems that the Google Monitoring Agent (powered by Stackdriver) should be installed on each Node (i.e. each compute instance, i.e. each machine) of a Kubernetes cluster.
However the new plugins, like Nginx, Redis, ElasticSearch..., need those agents to know the IP of these services. This means having kube-proxy running and set up which should mean running that Google Monitoring Agent on a Pod.
These two conflict: On one side that agent monitors the entire machine, on the other it monitor services running on one or more machines.
Can these Stackdriver plugins work on a Google Container Engine (GKE) / Kubernetes cluster?
