Permissions /cache

[martijndierckx]

Hi

I don't want to precreate the cache folder with the right permissions.
And the dockerfile doesn't do it either at the moment, so I worked around this using the following compose file:

services:
  esphome:
    container_name: esphome
    build:
      context: .
      dockerfile_inline: |
        FROM ptr727/esphome-nonroot
        RUN mkdir /cache
        RUN chown -R 1500:1500 /cache /config
        USER 1500:1500
        CMD ["entrypoint"]
    environment:
      - ESPHOME_DASHBOARD_USE_PING=TRUE
      - TZ=Europe/Brussels
    volumes:
      - /opt/esphome/:/config
      - cache:/cache
      - /etc/localtime:/etc/localtime:ro
    ports:
      - 6052:6052
    restart: unless-stopped

volumes:
  cache:
    driver: local

Would be great if you could adapt the dockerfile to chown/chmod the cache dir there, so I don't have to

I can't set permissions at runtime as the user the container runs under is not root.
I can't set permissions in the dockerfile as the user provided volume is not mounted.

You can try a two stage approach as is done the test compose file:

E.g.

services:
  # Set non-root permissions on created volumes
  # For testing only, not required if external volumes are used
  fix-volume-permissions:
    image: python:slim
    user: root
    command: bash -c "
      chown -R 1001:100 /config
      && chmod -R ugo=rwx /config
      && chown -R 1001:100 /cache
      && chmod -R ugo=rwx /cache"
    volumes:
      - esphome_config:/config
      - esphome_cache:/cache

  esphome:
    image: esphome:testing # See Dockerfile for build instructions
    # image: docker.io/ptr727/esphome-nonroot:latest
    container_name: esphome-test
    restart: unless-stopped
    depends_on:
      # Fix volume permissions before starting
      - fix-volume-permissions
    # Change the user to match the host configuration
    user: 1001:100
    environment:
      - ESPHOME_VERBOSE=true
      - TZ=Americas/Los_Angeles
    network_mode: bridge
    ports:
      - 6052:6052
    volumes:
      # Use persisted volumes in production
      - esphome_config:/config
      - esphome_cache:/cache
    tmpfs:
      - /tmp:size=1g,mode=1777

Let me know if you know of another more elegant way?
