Create local volume with custom mount options

General

That’s true but the permissions on the host folder will be set when you start the container. It doesn’t work with the usual bind mount, yes. But it works with the named bind mount when it is initialized. At least with Docker 20.10.10 which almost the latest version but I don’t think that matters. Maybe you misunderstand me so I give you an example to try:

Run on the host

mkdir $HOME/volumes/test

Dockerfile

FROM ubuntu:20.04
RUN mkdir /app && chown -R 33:33 /app

Note: I intentionally used 33 for UID and GID to make the change more noticable

docker-compose.yml

version: "3.7"

volumes:
  test:
    driver: local
    driver_opts:
      type: none
      device: "$HOME/volumes/test"
      o: bind

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - test:/app

Start the project:

docker-compose up -d --build

Check the permissions:

ls -la $HOME/volumes/test
