Habe eine Fehler bekommen beim Installieren von Nodered: Docker- Compose

@Jan-2005 : it's wrong (i think :) If you show logs for nodered's container with the command docker logs fhemdocker_nodered_1 --tail 40 --follow you can show a "permission denied" error :

npm ERR! Error: EACCES: permission denied, open 'npm-debug.log.896050243' npm ERR! at Error (native) npm ERR! { Error: EACCES: permission denied, open 'npm-debug.log.896050243' npm ERR! at Error (native) npm ERR! errno: -13, npm ERR! code: 'EACCES', npm ERR! syscall: 'open', npm ERR! path: 'npm-debug.log.896050243' } npm ERR! npm ERR! Please try running this command again as root/Administrator.

it's a common error when using docker, we don't pay attention to which user on the host run the container.

There are multiples solutions :

use sames userId groupId between the host and the containers ( contraints on the host : create a user with userId groupId than will be used in the containers ). Run the container with this user.
build container(s) with somes extras arguments ( args: directive ) and used them in the Dockerfile (examples : RUN groupmod -g $USER_GID www-data && usermod -u $USER_UID www-data OR RUN sed -i -e 's/fhem:.*/fhem:x:$USER_GID:20::\/opt\/fhem:\/bin\/bash/' /etc/passwd )
use build directive named user in order to associate the userId/groupId of the host and userId/groupId of the container

in your case the last solution is very easy, find your userId/groupId and set them in userdirective

For the userId :

id -u 1000

For the groupId :

id -g 1000

my user directive is user: "1000:1000"

Example :

version: '2'
