Could not get into docker container's bash: hydra container is restarting

Using this documentation : 1. I've pulled the vimagick/hydra docker image 2. Created docker-compose.yml file in ~/Soft/docker/ folder: hydra: image: vimagick/hydra command: sleep infinity volumes: - ./data:/data working_dir: /data restart: unless-stopped 3. Installed docker-compose 4. Executed: `docker-compose up -d Starting docker_hydra_1 ... done` 5. Executed: `docker-compose exec hydra bash Error response from daemon: Container ecf710f3f9526cf598c4a15a485fbfc3790a36e5f8b989820a157ba5453fc24f is restarting, wait until the container is running` docker ps gives: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ecf710f3f952 vimagick/hydra "bash sleep infinity" 20 hours ago Restarting (126) 20 seconds ago docker_hydra_1 93b5c43c6952 vulnerables/web-dvwa "/main.sh" 39 hours ago Up 23 minutes 0.0.0.0:80->80/tcp dvwatest $ docker exec -it ecf bash Error response from daemon: Container ecf710f3f9526cf598c4a15a485fbfc3790a36e5f8b989820a157ba5453fc24f is restarting, wait until the container is running I see that docker-compose.yml file contains restart: unless-stopped record. But why is it documented so and how to use this container when I could not connect to it? Thank you!
