I seem to have the same problem with version 2.17.3.
docker compose up -d
parsing /opt/docker-compose.yaml: yaml: unmarshal errors:
line 16: mapping key "container_name" already defined at line 5
line 17: mapping key "image" already defined at line 6
line 21: mapping key "restart" already defined at line 7
line 18: mapping key "volumes" already defined at line 12

Looks like this is already fixed. I don't have any issues with Compose v2.18.1.
