After running the following command
sudo docker-compose up
I get this error message
ERROR: The Compose file './docker-compose.yml' is invalid because: Unsupported config option for services.secrets: 'db_password'

This is my Docker version:
Client: Version: 18.09.3 API version: 1.39 Go version: go1.10.8 OS/Arch: linux/amd64 Experimental: false
I have already read several posts on this but I can't solve it. Can anybody tell me what I am doing wrong?
