Install Dockzen Host OS

It is very easy way to use dockzen. Light-weight Host OS(based on Tizen) is including all packages and it shows you the docker world rapidly.

Pre-condition

Target : Raspberry pi3
Host-OS : Light-weight Tizen

Process

Step 1. Flash SD card

• Download Tizen Host OS
• Format SD card
  $ sudo ./sd_fusing_rpi3.sh -d ./dev/sdX -format
• Flash boot into SD card
  $ sudo ./sd_fusing_rpi3.sh -d ./dev/sdX -b tizen-boot-20170629.tar.gz
• Flash Tizen OS into SD card
  $ sudo ./sd_fusing_rpi3.sh -d ./dev/sdX -b tizen-minimal_20170629.tar.gz

Step 2. Bring up Raspberrypi3

Step 3. Network Setting

• Set IP configuration through tool

Tizen support connmanctl as a network-mgr tool

# connmanctl  
connmanctl > services  
* AR Wired ethernet_X_cable
connmanctl > config  ethernet_X_cable --ipv4 manual 10.10.10.10 255.255.255.0 10.10.10.1
connmanctl > config  ethernet_XX_cable --nameservers 2.2.2.2 - Enable wifi or ethernet   

Tizen support wifi_test cli tool

# wifi_test 
1
Event received from stdin
Wifi init succeeded
Operation succeeded!
3
Event received from stdin
Operation succeeded!
[ 35.759546] brcmfmac: power management disabled
[ 35.776402] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
Wi-Fi Activation Succeeded
Device state changed callback, state : Activated
Event received from stdin 

• Check IP using ‘ifconfig’

Step 4. Check Containers info

tizen_headless.json : tizen platform container
dockzen_agent.json : agent container
These files say that which containers should be run and managed.
You can find these in /etc/dockzen/config/image/.
Agent container has functionalites of remote management via cloud server.

root@localhost:~# docker service ls
IDNAME   MODEREPLICAS  IMAGE
h9tuffapxqev  agent  replicated  1/1   10.113.62.204:443/dockzen-agent-arm:v1.0
qhyku7vejmxr  tizen  replicated  1/1   10.113.62.204:443/headless:v0.1

Step 5. Check Dash board (Optional)

Dockzen-agent has connection with dedicated cloud server.
You can get containers information from device via web pages in cloud server. currently we doesn’t open the enrolled cloud server and we have a plan to expose soon.
