Verify Network Performance in Docker Containers

If you're experiencing connectivity issues, you can use a Docker container to test your network speeds.

1️⃣ Pull the Python 3.9 Slim Docker Container

First, pull the Python 3.9 Slim Docker image to use for testing:

docker pull python:3.9-slim

2️⃣ Run the Docker Container

Start the container with the following command:

docker run -it --name speedtest-container python:3.9-slim /bin/bash

This command will start the container and open an interactive shell session.

3️⃣ Install the Speedtest Tool

Once inside the container, install the speedtest-cli tool using pip:    

pip install speedtest-cli

If you encounter issues, verify that Python and pip are installed with:

python --version
pip --version

4️⃣ Test the Network Speed

After the installation is complete, run the speed test:

speedtest-cli

The tool will provide the current network download and upload speeds, along with other metrics such as ping.

5️⃣ Cleanup the Docker Container

After completing the network test, you may remove the container to free up resources:

docker rm -f speedtest-container

If you see that your network speeds are less than expected, please open a ticket with us. We are aware of an issue between IO and Docker that limits the full capability of your network and are working towards a fix.
