The purpose of this project is to create a simple to run application that benchmarks different methods of building & pushing an image to minikube. Each benchmark is run multiple times and the average run time for the runs is calculated and output to a csv file to review the results.

This benchmarking tool is going to make changes to your Docker and minikube instances, so don't run if you don't want those to be disturbed. For example, the /etc/docker/daemon.json is modified and Docker is restarted, the following commands are run as well

minikube delete --all
docker system prune -a -f

• Docker needs to be installed
• Currently only supported on Linux (only tested on Debian)

The three current methods the benchmarks tests is using minikube docker-env, minikube image load, and minikube registry addon, with more being added in the future.

make

./out/benchmark # defaults to 100 runs per method

or

./out/benchmark --runs 20 # will run 20 runs per method

cat ./out/results.csv # where the output is stored

In the non-iterative flow the images/cache is cleared after every image build, making it so each build is on a brand new Docker.

In the iterative flow the images/cache is cleared at the end of a set of benchmarks. So if 20 runs per benchmark, no cache is cleared until all 20 runs have completed, just the last layer of the image is changed between runs.
