Docker install on synology nas

sdetweil

this turned out to be a permissions problem. the folder was created w the synology user, but the container is running as user 1000

I have the same issue but I do not really know how to run the container as user node with uid/gid 1000.

You wrote two ways with the hint that this should happen as root. How do I do this?

And can I make this run just for the MagicMirror docker? Because I have other dockers with other uids/gids.

Thanks for your help.

@pauabaer just change the docker compose .env file userid number from 1000 to whatever it is on your synology nas ( mine is 1026)
(note the . in front of env)

sdetweil

@pauabaer yes, the user info is separate for each docker container

think of a docker container as a mini pc disc, memory, cpu and software all inside a little case (container shell)

I tried it in the Synology gui. I have added puid and pgid as I did in other containers.

But I got the same message: access denied.

So what would be the difference when I change the entry whithin the compose?

And how do I find this file at my synology? :)

sdetweil

@pauabaer i do not know how to do it with the gui,
there is a place where you can paste in the compose file . i have not tried that

i ssh’d into the nas and did the manual install steps via commandline

I startet the container with a compose file where I added the user 1026 and group ID 100 but there is no success.

Still the same error - see attached file.

sdetweil

@pauabaer typically the group id is the same as the user id

sdetweil

@pauabaer

id -u will get this users id number
id -g will get this users group number

pauabaer

@sdetweil
That’s what i checked before. Id -u > 1026 / id -g > 100.
These parameters i inserted in the compose file.

I tried to start via command line


paua@NAS:~$ docker run  -d \

See 'docker run --help'.

But again I got the permission error.

I fixed it and now MM is running in docker on my synology diskstation.
I had to insert

user: root

in the compose file. It is working fine.
