Nextcloud AIO does not accept change of NEXTCLOUD_DATADIR

[kapanikos]

Hi,

for a few weeks now I'm trying to install Nexcloud AIO, starting with 8, now v9.0.1

I use an Ubuntu 24.04 LTS VM inside Proxmox with limited space, so I like to use an external DATADIR.
I mounted this to /data and want to use a folder nextcloud, so I thought the install command should look like this:

docker run
--init
--sig-proxy=false
--name nextcloud-aio-mastercontainer
--restart always
--publish 80:80
--publish 8080:8080
--publish 8443:8443
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config
--volume /var/run/docker.sock:/var/run/docker.sock:ro
--env NEXTCLOUD_DATADIR="/data/nextcloud"
--env NEXTCLOUD_MEMORY_LIMIT=1024M
nextcloud/all-in-one:latest

Whenever I tried to set this up, the DATADIR seems to remain unused and untouched. I've had countless retries now. Every time I'm retrying, I'm returning to a clean snapshot, without any docker containers.

On the Nextcloud AIO Interface the NEXTCLOUD_DATADIR is correctly shown. When I do a docker inspect of the nextcloud_aio_nextcloud container the NEXTCLOUD_DATADIR is also shown as I like it to be.

But when I'm sending files to Nextcloud, the folder is not used.

I thought userrights could be a problem, so I tried setting the folder from root:root to www-data:root and www-data:www-data forwards and backwards, but nothing changed.

What am I missing?

Has anybody an idea, what I could do? Everything else seems to work fine. The installed Nextcloud-clients like to connect to the new server, but I don't let them until their data is stored in the datadir I have prepared for them.

There are similar discussions already here, but they do not seem to resolve my problem :-(

Thanks in advance,
Kapa

Hi,

--env NEXTCLOUD_DATADIR="/data/nextcloud"

Can you post the outout of sudo ls -l /data/nextcloud here? (Please run the command on the host that runs docker and aio)

Hi,

of course I can, but it's no fun:

sudo ls -l /data/nextcloud
total 0

best,
Kapa

[kapanikos]

Any further ideas on this?
I tried on other systems, same problem. Maybe this is a bug?

[szaimen]

Can you post the output of sudo docker inspect nextcloud-aio-mastercontainer here?

[kapanikos]

Of course. Thanks for looking:

Thanks! We've found the culprit: you are using docker snap which is not allowed to use bind mounts in this location on the host afaik:

"NEXTCLOUD_DATADIR=/data/nextcloud",

Supported is only the /home/ folder and subfolders iirc.

But probably better to ask in a ubuntu forum...

[szaimen]

Btw, this is one of the reasons why it is disrecommended to use docker snap by the docker maintainers...

[szaimen]

Can you run sudo docker info and post the outout here? I want to add a warning for that to AIO.

[szaimen]

I found this: https://askubuntu.com/a/1033617

[kapanikos]

Aaaaaaaahhh! Right!

I completely forgot about snap (or ignored that fact ;-)) and and the limitations coming with it. That explains everything.
Thanks very much, haven't thought of that!

Thanks a lot again. Will try another distro or your linked article? Not sure by now :-)
