  • Abstract: Highlights The energy consumption is measured inside and outside Docker containers. Running the Docker daemon has an inherent power cost. Energy consumption in Docker is consistently higher than bare-metal Linux. The energy trade-off between containerization and enabling SSL is comparable. Abstract Context: Virtual machines provide isolation of services at the cost of hypervisors and more resource usage. This spurred the growth of systems like Docker that enable single hosts to isolate several applications, similar to VMs, within a low-overhead abstraction called containers . Motivation : Although containers tout low overhead performance, how much do they increase energy use? Methodology : This work statistically compares the energy consumption of three application workloads in Docker and on bare-metal Linux. Results : In all cases, there was a statistically significant ( t -test and Wilcoxon p  < .05) increase in energy consumption when running tests in Docker, mostly due to the performance of I/O system calls. Developers worried about I/O overhead could consider baremetal deployments over Docker container deployments.
