Releases

Github actions most of the work for you.

• At every push to main a new version is released to pypi. These are released at "pre-release" status.
• To make a new release, create a new tag with the following format: X.Y.Z. This will trigger a new release to pypi.

You just need to create a new release on github, and the action will take care of the rest.

Run iperf 3 benchmark on kubernetes without tool

There are two files in the folder benchmarks/bandwidth:

• the server iperf3-server.yaml
• the client iperf3-client.yaml

Results

• The results of our experiments are located in the results folder.
• Images and visualizations of data and analysis are located in the results/images folder.

TODO

• add a way to specify the namespace
• Run http benchmark until the server is up to 90% cpu usage
• loading bar for the benchmark
• Stream the output of the benchmark (Use streamlit)
• Move plot to "[plot]" depedencies, and make local imports in main, with error message helping to install plots
