Container unable to create node directory about gateway-docker HOT 13 CLOSED

Seems like a permissions issue with the volume you mapped into the container. I believe the node user in the container has uid/gid of 1000/1000, so the owner of your mapped directory needs to match.

That is odd as I am creating the container under the pi user which has an id of 1000 for both uid and gid.
I connected to the container and tried to manually create the directory, but to create it required sudo perms.
Is there a different perm I may be missing to allow it create the directory?

from gateway-docker.

I noticed that the directory you're trying to create is in /home/node and not /home/pi. I suspect that the permissions on /home/node (and subdirectories) may not be correct. Having said that, I've not really used docker on the Pi, so ignore me if this is just noise.

You definitely will need sudo permissions to create the /home/node directory, but that directory should be owned by a user and you shouldn't need sudo permissions to create sub directories under /home/node if you're running as the owner.

@dhylands In the docker container, node is the primary user, so that directory already exists.

@NuroDev What command are you using to start the container? I have a Raspberry Pi to test with again, so I'd like to try to reproduce.

from gateway-docker.

Using docker-compose, but same issue when running default provided command in README.md.

docker-compose.yml

version: "2"

services:
  gateway:
    image: 	mozillaiot/gateway:arm
    container_name: gateway
    restart: always
    network_mode: host
    cap_add:
      - NET_ADMIN
    volumes:
      - /home/nuro/gateway/:/home/node/.mozilla-iot

@NuroDev Why are you using /home/nuro/gateway? I thought you were running as the pi user? In that case, it should be /home/pi/gateway.

from gateway-docker.

My mistake, I mean't to say /home/pi/gateway. I usually use a .env file to store volume paths but for the sake commenting just manually input it 😅

from gateway-docker.

Haha, ok. So with /home/pi/gateway, it's still broken? Can you paste the output of stat /home/pi/gateway?

The directory is owned by root. This should fix your issue:

chown -R 1000:1000 /home/pi/gateway

from gateway-docker.

That seemed to fix perfectly! Thank you ❤️ 😄
