tfb command delete all my docker containers in local

[ilhooq]

Following the Quick Start instructions, I attempted the command:

./tfb --mode verify --test gemini

Unfortunately, this action resulted in the deletion of all my Docker containers.

Further investigation revealed that the tfb command utilizes the techempower/tfb Docker container, which is configured with the -v /var/run/docker.sock:/var/run/docker.sock volume mount. This allows the container to interact with the host machine's Docker daemon. The specific command being executed is:

exec docker run -i ${USE_TTY} --rm --network tfb -e USER_ID=$(id -u) -v /var/run/docker.sock:/var/run/docker.sock -v ${SCRIPT_ROOT}:/FrameworkBenchmarks techempower/tfb "${@}"

I also observed that the techempower/tfb container includes a toolset that contains a script ( tfb-shutdown.sh ) which includes a command that stops the docker daemon

FrameworkBenchmarks/toolset/continuous/tfb-shutdown.sh

Line 13 in 993b52b

docker ps --all --quiet | xargs --no-run-if-empty docker rm --force

Because the container shares the same Docker socket as the host, this script inadvertently deletes all local containers.

To prevent unexpected data loss, it would be beneficial to provide a warning to users before executing the ./tfb --mode verify --test gemini command, explicitly mentioning the potential impact of the Docker socket mounting.
