This section contains YAML files for the Docker Compose Stacks used in our Information Tech and Wireless Data Networking Classes.
OpenSpeedTest Server
The following stack creates an Open SpeedTest Server container. This server should not be run behind a reverse proxy or using SSL, as these mechanisms will distort the accuracy of the test results. It should also be noted that the absence of these important security mechanisms makes this tool unsuitable for use outside a closed, internal network environment.
#
# Open Speedtest - http version without SSL
# or a proxy. This ensures accurate results.
