I am using stable/prometheus-operator to deploy Prometheus. I added
additional scrape config for linux VMs to connect to the Prometheus.
However one of the node-exporter pod always shows pending. In the log, it
shows it doesn't match node selector. I added app: prometheus-node-exporter
in the additional Scrape config... Any advice?
