This document provides a quick start guide for setting up and using the Vigor3910 docker firmware. It outlines how to set the Linux IP address and port, check if docker is running, and install a docker image like Portainer for a web interface. The firmware adds docker support while keeping the original router functions and increases the firmware size and memory usage. Accessing docker requires configuring the Linux IP, port, and gateway appropriately.

2. Vigor3910 docker firmware
● 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
DPDK Fast Forward Engine
Linux System
DrayOS Virtual Machine
Linux IP
LAN Path
WAN Path

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
● http://192.168.1.3:9000 (replaced by your real linux IP, then you can access)
