src.freertr.net???? is my desktop notebook in my livingroom, thats why the hackish name :))))
at least sources.freertr.net .....
which is a random cloud that i trust the most right now.....
frederic, the fuck r u doing bro???? "
A basic FreerTr docker container
- Install docker on Dockerhost with the method of your choice
- Make sure that docker the container inherit from docker host DNS configuration
- Check this by issuing:
sudo docker run busybox nslookup www.google.com
git clone https://github.com/frederic-loui/freertr-docker.git
cd ./freertr-docker
sudo docker build --tag freertr/freertr:latest .
There are 2 files in ./freertr-docker/run :
./freertr-hw.txt
./freertr-sw.txt
These files are in the format -hw.txt and -sw.txt
As a start use the sample provided and replace eth2 by your NIC device (usually eth0)
In this sample file you'll indicate which Dockerhost interface will be bind to FreerTr container.
The line use to attach an interface to FreerTr container is:
int <network-device> eth <mac@> <bind_ip@> <tx_port> <bind_ip@> <rx_port> <br>
...
int eth2 eth 0000.1111.2222 127.0.0.1 22706 127.0.0.1 22705
int eth3 eth 0000.1111.3333 127.0.0.1 20011 127.0.0.1 20010
...

It is the FreerTr router configuration.

There is 2 processes that is run inside this container:
- A "control plane" process: This process is written in Java and can be run in user space
- A "data plane" process: This process is written in C run in kernel space and need thus more priviledges => This explain why we use --privileged flag. In addition
In addition FreerTr will manipulate the network interface attached to it.
=> This explain why we use --network host flag. In addition
sudo docker run --detach --privileged --network host -e "FREERTR_INTF_LIST=eth2/20010/20011" -e "FREERTR_HOSTNAME=freertr" -v "/home/kubeadm/freertr/run:/opt/freertr/run" --name freertr-001 freertr/freertr:latest
I would like to thank the original maintainer of FreerTr for this awesome piece of code.
If you need to understand networking protocol. Read the source, it is exceptionnally well written.
If you like reading IETF RFCs you will enjoy studying this code. (You'll save tons of sleeping pills ;-) )
Kudos to Csaba MATE then... all credits goes to him !
