How to run Prometheus monitoring with 1GB of RAM?

Question

Having tried all kinds of flags to avoid keeping much data on the RAM has not succeeded. Even if I restrict "storage.local.memory-chunks" and also "chunks to persistence". I have played around with different values of both parameters, I have almost 1TB of secondary storage attached to it, but still I run out of RAM.

The settings on https://github.com/RobustPerception/demo_prometheus_ansible/blob/master/roles/prometheus/tasks/main.yml run with all the main components under 1GB total. Depending on how many active time series there are and how much data queries are touching you may need more RAM.
