About this container

docker hub site

github source

This is a speedtest container using speedtest-cli on alpine-python3.8.

Based on docker hub python. with python:3.8-alpine Dockerfile.

Originally this container's idea comes from robinmanuelthiel/speedtest. His main implementation is shell script and sometimes does not work so I create a new Python implementation.

Dashboard

To configure Grafana, you need to add InfluxDB as a data source and create a dashboard with the upload, download and ping values. You can find a example dashboard configuration in the speedtest-dashboard.json.
