Appdaemon on docker + RPI3

Third party integrations AppDaemon
1

Hello everyone,

I’m struggling for a few hours with appdaemon on docker / RPI3
Docker is installed and is running ok.

1/ I git cloned the repo https://github.com/home-assistant/appdaemon on my RPI and changed the dockerfile with a
FROM resin/raspberrypi3-python:3.6.2

Original => https://github.com/home-assistant/appdaemon/blob/dev/Dockerfile

2/ Build the appdaemon image => OK

3/ Ran the following docker command :
`docker run --name=appdaemon -v /home/pi/appdaemon/conf:/conf -p 5050:5050 -e HA_URL=“http://192.168.1.105:8123” -e DASH_URL=“http://:5050$HOSTNAME” 76d1dca80fda``

and got the error :

Any help would be appreciated I don’t know why does this error pop up and how to solve it.
I read it’s maybe because of a perms issue but I logged in the container as root, tried to start appdaemon -c ./conf and same error.

Thank you very much.

I got around this by creating the directory and restarting the docker. It also complains that /conf/compiled/css doesn’t exist so create that too.

Yeah I did the same thing as a workaround and it works.
It’s definitely a permissions/ownership issue and UID between host and container as I understood.
I’ll dig that subject a little bit later

In case someone else finds this I had the same issues on Raspbian. I’m running this standalone (i.e. not on the same server as HASS) and had to manually create three directories, chown them and restart.

And similarly if using docker, I had to do the following:

  1. Start the docker container as described in http://appdaemon.readthedocs.io/en/latest/DOCKER_TUTORIAL.html
    It will complain about the missing directory

  2. shell into the running docker container as follows
    docker exec -i -t 94d2ca1a5782 /bin/bash

(where 94d2ca1a5782 was my container ID)

  1. Copy the conf tree from the container to your docker host:
    scp -r /conf somewhere:/mnt/data/containers/HomeAssistant/appdaemon/conf

  2. Stop the container with ctrl-C

  3. Create the directories under the conf tree on your docker host
    mkdir -p conf/compiled/javascript mkdir -p conf/compiled/css

  4. Start it again, adding the volume mount to your new conf tree

docker run --rm -it -p 5050:5050
-e HA_URL=“http://homeassistant.my.domain”
-e HA_KEY=“XXXXX”
-e DASH_URL=“http://appdaemon.my.domain:5050”
-v /mnt/data/containers/HomeAssistant/appdaemon/conf:/conf
acockburn/appdaemon:latest

Or if you want to run the container using its own IP address:

CONTAINER_SUBNET=“macvlan1”
CONTAINER_IPADDR=“192.168.0.81”
CONTAINER_DNS=“192.168.0.1”

docker run --rm -it
–net=${CONTAINER_SUBNET}
–ip=${CONTAINER_IPADDR}
–dns $CONTAINER_DNS
-e HA_URL=“http://homeassistant.my.domain”
-e HA_KEY=“XXXXX”
-e DASH_URL=“http://appdaemon.my.domain:5050”
-v /mnt/data/containers/HomeAssistant/appdaemon/conf:/conf
acockburn/appdaemon:latest
