● Special Firmware Based on V4.3.1
● Keep original router function
● Add some functions in firmware
○ Firmware size bigger
○ Use more memory space
■ Keep 150K connection
■ Check Memory Usage
● Need to set Linux IP
○ An IP in LAN subnet
○ Have security concern
■ No Linux IP more secure
● Run docker binary from
https://www.docker.com/

3. Quick Start (I) : Set Linux IP / Port / Gateway
● Set by DrayOS CLI
● mngt sethostlan <port> <Linux IP> <Gateway>
● Port : The port Management PC connected (Only this port can access Linux IP)
○ Usually set to P12 (P9 - P12 for fixed LAN in Vigor 3910)
● Linux IP (LAN subnet)
● Gateway
=DrayOS LAN IP
● Test by Ping Linux IP
● Telnet into Linux Shell

4. Linux / DrayOS / DPDK Relationship

5. Quick Start (II) : Check Docker Running Status
● Check if dockerd running
○ if not , check /sbin/docker_init.sh
● Run docker search command
○ if no response, check Linux IP/Port/Gateway Settings
● Now you can install docker image by docker command
● *Trouble Shooting Command
○ ifconfig docker0 (should have additional interface docker0)
○ route (should show a route docker0)
○ docker info (show docker information)

6. Example : Install Docker Web Interface (Portainer.io)
● https://www.portainer.io/
Install Step #1
docker volume create portainer_data
Install Step #2
docker run -d -p 9000:9000 --name=portainer --restart=unless-stopped -v /var/run
/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

7. Access Portainer Web Interface
