Dropbox CLI in Podman rootless

Contact: Robert Nowotniak [email protected]

If you don't want to run a proprietary and closed-source Dropbox CLI directly on your host machine, you can use this project, to run Dropbox in a podman container.

Build the image

$ git clone https://github.com/rnowotniak/podman-dropbox.git
$ cd podman-dropbox

$ podman build -t dbox . # --no-cache # (there might be a newer Dropbox version available on the upstream)
(...)

$ podman images
REPOSITORY      TAG         IMAGE ID      CREATED      SIZE
localhost/dbox  latest      9e20bf2a248b  2 hours ago  269 MB
$ _

Run the container

DROPBOX_DIR=/mnt/sata/Dropbox-podman      # it will contain Drobox installation, and Dropbox/ subdir with your files
DROPBOX_HOSTNAME=`hostname`-podman-dbox   # you will see this in your linked devices list in Drobox security panel

podman run --hostname=$DROPBOX_HOSTNAME --name dbox -d -v $DROPBOX_DIR:/root dbox

Caveat: Dropbox tries to auto-update itself on a regular basis. (see: https://wiki.archlinux.org/title/dropbox#Prevent_automatic_updates ). This podman image takes care of this, and handles it accordigly (in run.sh script).

$ podman exec -it dbox dropbox.py exclude remove Dropbox/Photos   # sync selectively, remove dir from the exclude list

Notes

Include in the image:

  1. dropbox.tgz -- download during the image build, and incorporate in the container przezimage
  2. dropbox.py -- should be in the image

When the container is launched:

  1. ~/.dropbox-dist - will be installed when the container is launched, from dropbox.tgz
  2. start ~/.dropbox-dist/dropboxd

When Dropbox daemon is started:

  1. ~/.dropbox (state, settings, exclude etc) - per container, created when dropbox is started
  2. ~/Dropbox (files) - db installer tries to recreate it - per container, created when dropbox is started
