Re: bring it on!
In this paper, we compared the energy consumption
of various workloads running within Docker-managed
containers and on “bare-metal” Linux. After almost
2 days and 20 hours of total time collecting power
measurements, we found that, in all cases, workloads
running in Docker have a measurable energy overhead.
Simply running dockerd idle induces a 2 watt
difference in average power, and thus an increase in
energy over time. However, the increase in energy
consumption may mostly be attributed to runtime
performance. In the case of Redis and WordPress,
the increase in energy can be attributed to increase in
runtime—thus the decrease in performance explains
the increase in total energy consumption.
