dangling volumes due to `VOLUME /var/log/letsencrypt`

[abdeldjalil-fellah]

because of VOLUME /var/log/letsencrypt in Dockerfile dangling volumes keep created when no volume is set for /var/log/letsencrypt in docker compose file. please remove that statement to avoid this issue.

Does anyone know of a possibility to do something like a dummy mapping to avoid this issue?

Am experiencing the same issue. No resolution?

Simply mount volume on /var/log/letsencrypt

cli :

docker run --rm -d --name speedtest -v openspeedtest:/var/log/letsencrypt -p 3000 openspeedtest/latest

docker-compose.yml :

volumes:
  openspeedtest:
services:
    image: openspeedtest/latest
    hostname: speedtest
    expose:
      - 3000
    volumes:
      - openspeedtest:/var/log/letsencrypt

Adjust the port configuration depending on whether you're behind a reverse proxy or not.
