Fails on raspberry zero w

AnderssonPeter commented 6 years ago

Hi im trying to use this container using docker-compose

  nfsserver:
    image: itsthenetwork/nfs-server-alpine:9-arm
    restart: unless-stopped
    volumes:
      - /data/share:ro
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    environment:
      SHARED_DIRECTORY: /share
      READ_ONLY: 'true'
    privileged: true
    ports:
      - "2049:2049/tcp"
      - "2049:2049/udp"
      - "111:111/tcp"
      - "111:111/udp"

using the same setup on a pi3 works.

log:

The PERMITTED environment variable is missing or null, defaulting to '*'.

Hey. It looks like confd is causing this issue. Also, you are specifying a SHARED_DIRECTORY of /share but mounting in /data/share which won't help. Also note there is no need to expose port 111 for either TCP or UDP, or port 2049 for UDP (it'll only work over TCP).

I'm in the usual position where I can't test this in any way. What I will do (which I need to do anyway as there is an apk bug in Alpine v3.7) is rebuild the x86 and arm images tonight with Alpine v3.8 if possible. This will also make use of the multistage build changes introduced recently which might help.

Ultimately though it'll be luck if this helps. What might be better is if I ditch confd entirely and switch to using sed/awk to build the exports file. This will remove the need for the multi-stage build and make the image much smaller. I'll give that some thought.

Thanks for your fast reply! - /data/share:ro was a typo it was supposed to be - /home/peter:/share:ro, and that is what i was running with. So that's not the issue. If you get the time to create a updated docker image please give me a shout out and ill check if your changes work or not!
