Docker shared volume creation -


i trying create docker volume shared between 2 hosts. let's have 2 hosts , b. when volume created on host following command:

docker volume create --driver local --opt type=nfs --opt o=addr=b,rw --opt device=:/tmp/dir --name foo

after inspection of volume, result following:

  docker volume inspect foo  [     {     "name": "foo",     "driver": "local",     "mountpoint": "/var/lib/docker/volumes/foo/_data",     "labels": {},     "scope": "local"     }  ]

my question is: why mountpoint directory of volume doesn't point directory /tmp/dir, default docker volume location? how can consider data in directory host b/tmp/dir sharable?

thanks in advance!

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
