Use GVfs as a backend for docker volume
Status : proof of concept (working)
By using GVfs this plugins allow the use of various backend as storage.
Dedends on gvfs and gvfsd-fuse (so dbus indirectly)
Packages :
Working: SSH/SFTP/DAV/DAVS/FTP
In Progress/Not tested: FTPS/NFS/SMB/CIFS/...
make
./docker-volume-gvfs daemon
OR in a docker container
docker run -d --device=/dev/fuse:/dev/fuse --cap-add=SYS_ADMIN --cap-add=MKNOD -v /run/docker/plugins:/run/docker/plugins -v /var/lib/docker-volumes/gvfs:/var/lib/docker-volumes/gvfs:shared sapk/docker-volume-gvfs
For more advance params : ./docker-volume-gvfs --help OR ./docker-volume-gvfs daemon --help
Run listening volume drive deamon to listen for mount request
Usage:
docker-volume-gvfs daemon [flags]
Flags:
-d, --dbus string DBus address to use for gvfs. Can also set default environment DBUS_SESSION_BUS_ADDRESS
-o, --fuse-opts string Fuse options to use for gvfs moint point (default "big_writes,allow_other,auto_cache")
Global Flags:
-b, --basedir string Mounted volume base directory (default "/var/lib/docker-volumes/gvfs")
-v, --verbose Turns on verbose logging
docker volume create --driver gvfs --opt url=ftp://user@url --opt password=pass --name test
docker run -v test:/mnt --rm -ti ubuntu
NB : For mounting SSH/SFTP it is usefull to set a ssh_config file for the running user in order to use a ssh key as authentification.
docker plugin install sapk/plugin-gvfs
docker volume create --driver sapk/plugin-gvfs --opt url=ftp://user@url --opt password=pass --name test
docker run -v test:/mnt --rm -ti ubuntu
volumes:
some_vol:
driver: sapk/plugin-gvfs
driver_opts:
url: "ftp://user@url"
password: "pass"
If when trying to start a container you get this error :
docker: Error response from daemon: chown /var/lib/docker-volumes/gvfs/ftp:host=10.8.0.7,user=sapk: function not implemented.
Try to start the container with the :nocopy attribute on the volume like that :
docker run -v test:/mnt:nocopy --rm -ti ubuntu
