1. Open fdisk

   [root@alarmpi ~]# fdisk /dev/mmcblk0

   Welcome to fdisk (util-linux 2.24.1).
   Changes will remain in memory only, until you decide to write them.
   Be careful before using the write command.
   
   
   Command (m for help): 
   

2. Press ‘p’ to print the partition table:

3. Press 'd' to delete a partition:

   1. Enter '2' to choose the second partition.

   Command (m for help): d
   Partition number (1,2,5, default 5): 2
   
   Partition 2 has been deleted.
   

4. Press 'n' to create a new partition:

   1. Enter 'e' to select extended as partition type.
   2. Partition number: to accept 2 as default partition number.
   3. First sector: to accept default.
   4. Last sector: to accept default.

   Command (m for help): n
   
   Partition type:
      p   primary (1 primary, 0 extended, 3 free)
      e   extended

   Created a new partition 2 of type 'Extended' and of size 14.7 GiB.
   

5. Press 'n' to create a new partition:

   1. Enter 'l' to select logical as partition type.
   2. First sector: to accept default.
   3. Last sector: to accept default.

   Command (m for help): n

   Created a new partition 5 of type 'Linux' and of size 14.7 GiB.
   

6. Press 'w' to write the new partition table.

   Command (m for help): w
   The partition table has been altered.
   Calling ioctl() to re-read partition table.
   Re-reading the partition table failed.: Device or resource busy
   
   The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).
   [root@alarmpi ~]# 
   

7. Reboot to force the kernel to recognize the new parition table

   [root@alarmpi ~]# reboot

8. Reconnect to raspberry

   ssh [email protected]

9. Execute following command

   [root@alarmpi ~]# resize2fs /dev/mmcblk0p5

   resize2fs 1.42.9 (28-Dec-2013)
   Filesystem at /dev/mmcblk0p5 is mounted on /; on-line resizing required
   old_desc_blocks = 1, new_desc_blocks = 1
   The filesystem on /dev/mmcblk0p5 is now 3836672 blocks long.
   

10. Control if everythink worked

    [root@alarmpi ~]# df -h
    Filesystem      Size  Used Avail Use% Mounted on
    /dev/root        15G  416M   14G   3% /

    tmpfs           232M     0  232M   0% /dev/shm
    tmpfs           232M  288K  231M   1% /run
    tmpfs           232M     0  232M   0% /sys/fs/cgroup
    tmpfs           232M     0  232M   0% /tmp
    /dev/mmcblk0p1   90M   25M   66M  28% /boot
    

Setup timezone

1. Find out the current configured timezone

   [root@alarmpi ~]# timedatectl status

2. List avaiable timezones

   [root@alarmpi ~]# timedatectl list-timezones

3. Set your timezone (for example Europe/Berlin)

   [root@alarmpi ~]# timedatectl set-timezone Europe/Berlin

Change hostname

1. Set the hostname to your liking (e.g. arch):

   [root@alarmpi ~]# hostnamectl set-hostname arch

2. Add the same hostname to /etc/hosts:

   [root@alarmpi ~]# nano /etc/hosts

   #
   # /etc/hosts: static lookup table for host names
   #
   
   #<ip-address>   <hostname.domain.org>   <hostname>
   127.0.0.1       localhost.localdomain   localhost arch
   ::1             localhost.localdomain   localhost arch
   
   # End of file
   

   1. After you add your hostname press "crtl+x", "y" and hit "enter" to exit nano and save your changes

Install Software

1. Docker with the needed kernel extensions

   [root@alarmpi ~]# wget -O - https://raw.github.com/resin-io/docker-install-script/master/install.sh | sh
   

2. Enable ip forwarding

   [root@alarmpi ~]# echo 'net.ipv4.ip_forward=1' >> /etc/sysctl.d/40-ip-forward.conf

3. Enable docker service at startup

   [root@alarmpi ~]# systemctl enable docker.service

4. Reboot

   [root@alarmpi ~]# reboot
