`docker-compose` command not found on CI runners and new installs: Compose v1 is retired, use `docker compose`
# before
docker-compose up -d --build
docker-compose down -v
# after
docker compose up -d --build
docker compose down -v
On Linux hosts without the plugin, install the distro package docker-compose-plugin from Docker's apt/yum repo. If third-party tooling hard-codes docker-compose on Docker Desktop for Mac, recreate the symlink to the v2 plugin (recommended by a Docker maintainer):
sudo ln -sf /Applications/Docker.app/Contents/Resources/cli-plugins/docker-compose /usr/local/bin/docker-compose
Symptom
Scripts or CI steps calling docker-compose up (with a hyphen) fail because the docker-compose command is not found. Tutorials and model output still use the hyphenated v1 command.
Cause
Docker Compose v1 (docker-compose, Python) stopped receiving updates in July 2023 and is retired; Docker's retired-products page says it is superseded by Compose v2 (docker compose, a Go CLI plugin). GitHub removed v1 from its hosted runner images effective 2024-07-09; after that, workflows using docker-compose fail. Newer Docker Desktop releases no longer offer a v1/v2 toggle.
Verify
docker compose version prints Docker Compose version v2.x or v5.x.
