Node metrics available inside of a container (opens in new tab)

Several people asked me this question: Could we get Node metrics inside of a container? Usually, this comes from the fact that PMM or standalone people run node_exporter inside a container. PMM does it as a sidecar along with many other exporters to monitor DBs, and node_exporter comes out of the box as a default one. So people could see accurate data on dashboards, like Memory and CPU, that node_exporter reads inside the container.
