Docker Error bind: address already in use

Question

When I run docker-compose up in my Docker project it failes with the following message:

Error starting userland proxy: listen tcp 0.0.0.0:3000:          


        

Answer 1

This helped me:

docker-compose down  # Stop container on current dir if there is a docker-compose.yml
docker rm -fv $(docker ps -aq)  # Remove all containers
sudo lsof -i -P -n | grep   # List who's using the port

and then: kill -9 (macOS) or sudo kill (Linux).
