Snappy first hands on ARM7 - inqueries / setup issue

[Beaudenon Remy]

Hi 

I'm beginner with Ubuntu and Raspberry device.I  successfully installed  "Snappy Ubuntu" on a Raspberry PI Mod. 2 . ( ARM7 architecture ) 
I'm facing with some inqueries / issues ....  Could please provide some help.
   
   - KeyBoard    

 How to switch Keyboard layout to "AZERTY" mode... (French keyboard )   
   
   - Micro SD card  Installation format.
  i have Disk  /dev/mmcblk0: 7.5 GiB   ==>  15.644.672 sectors  Only about 3 GiB is used after the installation. 
  Do we need to extend  manually or is there any automatic extend program ? .  Please explain
    
  Device         Boot   Start     End Sectors  Size Id Type
 /boot           /dev/mmcblk0p1 *       8192  139263  131072   64M  c W95 FAT32 (LBA)
/                   /dev/mmcblk0p2       139264 2236415 2097152    1G 83 Linux
                    /dev/mmcblk0p3      2236416 4333567 2097152    1G 83 Linux
/writable      /dev/mmcblk0p4      4333568 5857279 1523712 744M 83 Linux   
   - Ras PI Mod 2. doesn't save the 'Date'.We have some certificate issues with some snappy commands. Is it possible to setup a network  (NTP) ?        

   
   -  Wireless connection  Issue      
 i connected a802.11 WLAN on the USB device .  [   16.679145] usb 1-1.3: Product: 802.11n WLAN Adapter
[   16.684143] usb 1-1.3: Manufacturer: Realtek
Snappy Ubuntu security framework don't allow the Root id to update system files.  
==>  cant't edit  /etc/network/interfaces
How can we process to setup wireless adaptor ? Do we need to disable the  security layer ?
In case i known how to edit/save  a system file   is this following setup is correct  ? 
-- Update --- 
auto lo
iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0

iface wlan0 inet dhcp
   wpa-ssid "Your Network SSID"
   wpa-psk "Your Password"

source-directory /etc/network/interfaces.d   // do we need to comment this  previous line ? 
--------------   
   -  Build a sample project for snappy on PI Mod 2     

I'm looking for some education to create , build , deploy and  run  samples application on SNAPPY Ubuntu 

   
   - Please confim the dockers framework is not available for ARM7 architecture. 

Thanks for your supports.
