Install

Docker with the Compose plugin (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md#L26-L48)
A host with Docker and the Docker Compose plugin. This entry runs from a compose file.
Save the code block as docker-compose.yml (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md)
Use the compose file shown above.
What the compose file check ran with (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md#L26-L48)
This compose file is copied unchanged from the code block in https://github.com/librespeed/speedtest/blob/4cf44ad6ac0618a201d5e2f14a9f30cbfcdab8cb/doc_docker.md#L26-L48. The check ran on that block alone. The Docker guide shows this docker-compose.yml configuration for running the speed test.
Start it (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md)
```
docker compose up -d
```
Open the app (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md)
Open http://localhost:80. The compose file publishes host port 80 for the speedtest service. The guide says the test can be accessed on port 80.

Gotchas and maintenance

Gotchas

Some images use the latest tag or no tag. Images without a pinned version: speedtest: ghcr.io/librespeed/speedtest:latest. A later pull can get a different version. (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md, checked 2026-10-22)
The compose file publishes host ports. Host ports: 80 (speedtest). A port without a host address listens on all host network interfaces. (github.com/librespeed/speedtest/blob/4cf44ad/doc_docker.md, checked 2026-10-22)
