Why I cannot see filesystem in result of df -h?

When I list all of filesystems with df -ha command I can see following result:

user@server:~$ df -ah
Filesystem            Size  Used Avail Use% Mounted on
proc                     0     0     0   -  /proc
sysfs                    0     0     0   -  /sys
udev                  3,9G  100K  3,9G   1% /dev
devpts                   0     0     0   -  /dev/pts

when i go to the ~/depoly directory and execute df -ha . I can see following filesystem:

user@server:~/deploy$ df -h .
Filesystem            Size  Used Avail Use% Mounted on
-                     229G  171G   46G  79% /

Can someone explain why I cannot see this 229G filesystem / in the output of command df -ha?
