Docker (Compose) log file permissions error "Permission denied: '/logs/SunGather.log'"

[iDontWantAUsername]

Hi, I am running this in Docker-Compose:

version: '3.3'
volumes:
  sungather_logs:

services:
  sungather:
    container_name: sungather
    image: bohdans/sungather:latest
    network_mode: host
    ports:
      - 8090:8090
    volumes:
      - /etc/sungather/config:/config/
#      - /var/log/sungather/:/logs/
#      - /etc/sungather/logs:/logs/
      - sungather_logs:/logs/
    environment:
      - TZ=Australia/Melbourne
    restart: unless-stopped

I have tried all 3 of the volumes for the logging however in all cases i get:

When the log file is active in the config e.g.: log_file: DEBUG

Is this a defect with the docker image?

Let me test and get back to you :)

What permissions do you have on the directory sungather_logs? Where is the directory located? You should use absolute paths on paths to volumes. Then check the permissions. You should have write permissions for the same user that starts the docker container.

I had the same problem. Adding user: root fixed it for me

services:
  sungather:
    image: bohdans/sungather:latest
    container_name: sungather
    restart: always
    network_mode: host
    user: root
    environment:
      - TZ=Europe/Berlin
    ports:
      - "8080:8080"
    volumes:
      - /volume1/docker/sungather/config.yaml:/config/config.yaml
      - /volume1/docker/sungather/logs/:/logs/
