The docker-compose.yaml doesn't work for me, I get this error

docker-compose -f dc.yaml up -d

ERROR: The Compose file './dc.yaml' is invalid because:

'grafana' does not match any of the regexes: '^x-'

You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.

For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

I later modified the compose file as below, to get it working

version: '3'

services:

grafana:

image: grafana/grafana:7.5.7

ports:

- 3000:3000

restart: unless-stopped

volumes:

- ./grafana/provisioning/datasources:/etc/grafana/provisioning/datasources

- grafana-data:/var/lib/grafana

volumes:

grafana-data:
