Tweaked your compose.yml file a bit, got it running ```yml volumes: sonar-db: services: sonarr

volumes:
  sonar-db:

services:
  sonarr:
    image: lscr.io/linuxserver/sonarr:latest
    container_name: sonarr
    environment:     
      - PUID= 1000
      - PGID= 1000 
      - TZ=Europe/Amsterdam
    volumes:
      - sonar-db:/config
      - ./sonar/data:/data
    ports:
      - "8989:8989"
