Hide Forgot
Description of problem: If you use docker in a graphical environment, when you start a container - the mounted filesystem will be shown in Gnome Files explorer. I don't think there is any benefit in it - even more - there is some danger that we can unmount the filesystem by accident. I would like to see these filesystems hidden. I'm assigning this to docker-io component to get more opinions, later we can move it to Gnome if this will be accepted.

Hi Alex, I'm guessing you'd be the goto person for this(?)
What's needed is (I think) UDISKS_IGNORE [1] [2]. [1] https://git.gnome.org/browse/gvfs/tree/monitor/udisks2/what-is-shown.txt [2] udisks.8 This may be as simple as having a standard naming convention for Docker's DM devices and adding a udev rule.
In general we don't show anything unless its in some standard locations like /media, /run/media, or $home. However there are two devices here that are still shown, as they are not mounted, so there is no mountpath that we can ignore it via. The first is the devicemapper pool (dm-0). It has: by-id: /dev/disk/by-id/dm-name-docker-0:31-15758192-pool So maybe we can mark this via udev rules. The second is the loopback device that is used for the devicemapper pool. I don't see how we can ignore this though: ======================================================================== Showing information for /org/freedesktop/UDisks/devices/loop0 native-path: /sys/devices/virtual/block/loop0 device: 7:0 device-file: /dev/loop0 presentation: /dev/loop0 by-id: /dev/disk/by-uuid/1cb3cade-41d1-4c3b-a0d0-246783dbfecd detected at: Thu 28 Nov 2013 14:31:36 CET system internal: 1 removable: 0 has media: 1 (detected at Thu 28 Nov 2013 14:31:36 CET) detects change: 0 detection by polling: 0 detection inhibitable: 0 detection inhibited: 0 is read only: 0 is mounted: 0 mount paths: mounted by uid: 0 presentation hide: 0 presentation nopolicy: 1 presentation name: presentation icon: automount hint: size: 107374182400 block size: 512 job underway: no usage: filesystem type: ext4 version: 1.0 uuid: 1cb3cade-41d1-4c3b-a0d0-246783dbfecd label: loop: filename: /dev/loop0 drive: vendor: Linux model: Loop: loop0 revision: serial: WWN: detachable: 0 can spindown: 0 rotational media: Yes, unknown rate write-cache: unknown ejectable: 0 adapter: Unknown ports: similar devices: media: compat: interface: (unknown) if speed: (unknown) ATA SMART: not available
Created attachment 830245 [details] udev rules to ignore docker devmapper block devices With this rule we get rid of one of the icons. But i have no idea how to avoid showing the loop0 one.
It seems like we should be able to match on the backing file, but: SUBSYSTEM=="block", NAME=="loop*", ATTR{loop/backing_file)=="/var/lib/docker/*", ENV{UDISKS_IGNORE}="1" doesn't seem to work.
