Start as root #7

kopax · 2016-03-29T14:59:22Z

for some reasons (describe below), I need to test as root user dropbox, is there a simple way to do that?

Reasons:

I have started a container with --volumes-from=another_data_container on host A.
another_data_container was writing file as uid 1000 gid 1000.
I have added a group with gid 1000 in dropbox, and added dropbox user into the group.
Into another_data_container, I have updated folders permissions using find . -type d -exec chmod g+rwx and files permissions usings find . -type f -exec chmod g+rw
I linked my dropbox account
file got synced to dropbox (without adding group permissions, dropbox wasn't allowed to upload those files)
I have started a container with --volumes-from=another_data_container on host B

Dropbox container from host B should download another_data_container files but I have the following error :

    dropbox status
    Syncing (34 files remaining)
    Downloading 34 files...
   Can't sync "myfile.txt" (permission denied)

Permissions of this file as been uploaded to dropbox with UID 1000/GID 1000 so for me it should work.

The text was updated successfully, but these errors were encountered:

--volumes-from=another_data_container

What volumes does another_data_container expose?
I hope just /dbox/Dropbox and not /dbox!

First check that the directory /dbox/Dropbox in another_data_container is owned by UID 1000/GID 1000 and that they have read/write/exec permissions for that folder.
Check that myfile.txt inside the folder is also owned by UID 1000/GID 1000.

Given that all the above checks out you should be able to run the dropbox container like this (No need to modify users/groups inside the container):

docker run -d --restart=always --name=dropbox \
-e DBOX_UID=1000 \
-e DBOX_GID=1000 \
--volumes-from=another_data_container \
janeczku/dropbox

another_data_container expose:

In Docker file : VOLUME /etc/myapp
At runtime : --volume /etc/myapp --volume /dbox/Dropbox/srv/docker/company/myapp-data/

The folder /dbox/Dropbox/srv/docker/company/myapp-data/ has been created by another_data_container using the following start.sh script as entrypoint:

#!/bin/bash
VOLUME_DROPBOX="/dbox/Dropbox/srv/docker/company/myapp-data"
VOLUME_MYAPP="/etc/myapp"
echo "Create company/myapp directory"
mkdir -p ${VOLUME_DROPBOX}
mkdir -p ${VOLUME_MYAPP}
echo "Create symoblic link from myapp to dropbox"
mkdir -p ${VOLUME_DROPBOX}${VOLUME_MYAPP}
ln -svf ${VOLUME_MYAPP} ${VOLUME_DROPBOX}${VOLUME_MYAPP}
echo "Container ready"
exit 0

I have verified that symbolic link inside my Dropbox container and files are present.

Also, permissions of /dbox/Dropbox is not UID 1000/GID 1000 but UID 200/GUID 200.

myfile.txt is owned by UID 1000/GID 1000 and located in /dbox/Dropbox/srv/docker/company/myapp-data/etc/myapp/myFile.txt.

I have tried your recommendation of fixing the UID/GID to 1000.

I still have the same errors when trying to downloading file : Can't sync "myfile.txt" (permission denied)

Even if it would have worked, It is not the best way to implement dropbox in my situation, I am planning to attach more than one volumes from more data containers to this Dropbox instance.

Data from other volumes can be from different group.

It could be nice if we could run Dropbox as root.

janeczku · 2016-03-29T17:08:35Z

I see. To give Dropbox super privileges (same as running as root) you should just pass DBOX_GID=0 (do not also set DBOX_UID to 0!). Try this:

docker run -d --restart=always --name=dropbox \
-e DBOX_GID=0 \
--volumes-from=another_data_container \
janeczku/dropbox

kopax · 2016-03-29T17:23:06Z

root@b803b686c1bb:/# dropbox status 
Syncing (34 files remaining)
Downloading 34 files...
Can't sync "myfile.txt" (permission denied)
root@b803b686c1bb:/# id dropbox
uid=1000(dropbox) gid=0(root) groups=0(root)

So far I have 3 suppositions left :

I am trying to write in a symbolic folder that point to /etc/myapp into the dropbox container and I don't have the right. (Wait !! super privilege give me the right to do anything so it can't be true)
Dropbox client issue.

Docker volumes miss usage.

root@b803b686c1bb:/etc# ls -altr /etc/myapp
total 8
drwxr-xr-x  2 root root 4096 Mar 29 16:54 .
drwxr-xr-x 53 root root 4096 Mar 29 17:19 ..

Any advices are well appreciated.

janeczku · 2016-03-29T17:47:11Z

What user/permissions is set for "myfile.txt" when you exec into the running dropbox container and check from there?

janeczku · 2016-03-29T17:48:26Z

Also paste owner/permission of /dbox and /dbox/dropbox from inside the running container!
Actually do that for every folder in the chain:

/dbox/Dropbox/srv/docker/company/myapp-data

kopax · 2016-03-29T18:30:53Z

myfile.txt is present, uid 1000 gid 1000, but it's only in the dropbox container that send, the container that just received doesn't receive because of the permissions.

From the dropbox container that send to dropbox.com :

Exec to one of the containers where dropbox is running. Then run:

usermod -s /bin/bash dropbox
su dropbox
cat /dbox/Dropbox/srv/docker/company/myapp-data/etc/myapp/myapp/myapp.txt
cat /etc/myapp/myapp/myapp.txt

Je ne comprends pas bien le sens de ce test.
Ce que je veux dire, c'est qu'effectuer ces commandes sur le client qui à servi à synchroniser sur dropbox, c'est normal que les fichiers soient présent (puisqu'il sont sur dropbox).
Tandis que c'est normal que le fichier ne soit pas présent sur le client qui réceptionne, puisqu'il rencontre d'abord le problème de droit.

I think we had a misunderstanding here. I thought the Can't sync "myfile.txt" (permission denied) error occurs on the sending client. But apparently the file is uploaded to Dropbox successfully, but cannot be downloaded, right? Looks like a Dropbox problem.

kopax · 2016-03-31T03:45:53Z

I reopen this issue because it is not solved.

For Dropbox, it's the client which is not up to date.

For you and for me, it is Dropbox client the problem.

Mise à jour par : Benedict, 30 mars 8:57 AM:

Bonjour Monsieur,

Merci de nous avoir contacté. Je comprends que vous recevez une message d'erreur avec un fichier dans votre Dropbox.

Après avoir vérifié votre compte, il semble que vous utilisez une ancienne version de l'application Dropbox sur votre ordinateur. Le problème que vous rencontrez devrait disparaître une fois que l'application est mise à jour.

Pour mettre à jour l'application, suivez ces instructions :

Quittez l'application Dropbox depuis le menu Dropbox. Faites un clic droit sur l'icône Dropbox et sélectionnez "Quitter"

Téléchargez la version actuelle de Dropbox en visitant le site Internet de Dropbox :

https://www.dropbox.com/downloading

Lancez l'installateur

Pendant le processus d'installation, il vous sera demandé si vous avez déjà un compte. Entrez l'adresse e-mail et le mot de passe du compte Dropbox que vous souhaitez synchroniser.

Si votre Dropbox était déjà synchronisée avant de réinstaller, la ré-indexation des fichiers ne prendra que très peu de temps et la synchronisation devrait recommencer rapidement.

Merci d'utiliser Dropbox et n'hésitez pas si vous avez d'autres questions.

Cordialement,
Benedict

Please not that the client crash on every docker instance, after 10 to 20 minutes.
I wonder if this bug is related to my sync issue that make all client buggy ?
(I haven't talk about yet for that reason.)

Please do not close the issue until we haven't found the source of the problems.
This because your Dropbox is first on hub.docker.io and people might need to know what are the current encountered issue.

So far I see this possibles issues :

Dropbox wrong version (we need to check for new version, wasn't the version bumped 15 days ago? Did it get upgraded by Dropbox meanwhile ?)
Dropbox current version issue (we should be able to reproduce the bug on your host)
Unstable docker container (We still need a reason)
Is working with symlink between data containers not recommended ? (We need a demo)

Dropbox current linux version available is 3.16.1.
Error is related to the client builded in this image.
Keeping open the issue is legit isn't it ?

janeczku · 2016-03-31T16:58:31Z

Dropbox current linux version available is 3.16.1.

The image has the latest version:

$ docker logs dropbox
dropboxd(3.16.1) started...

I just had another idea: Apparently dropbox writes error reports to the /tmp folder (see here). With the current image this does not work though.

Please run this development image for the receiving client: janeczku/dropbox:devel.
After you see the error Can't sync "myfile.txt" (permission denied) you exec to the container
Check if there are any files like/tmp/dropbox_errorXXXX.txt and copy/paste the content here.

docker run -d --name=dropbox \
-e DBOX_GID=0 \
--volumes-from=another_data_container \
janeczku/dropbox:devel
