Dockerfile: Quagga BGP Tutorial

A fedora based container for Iljitsch van Beijnum's quagga BGP tutorial.

Pull pre-built image

docker pull alectolytic/quagga-bgp-tutorial

Build from source

docker build --tag alectolytic/quagga-bgp-tutorial .

Run

Create configuration directory on host

export QUAGGA_CONFIG=$(pwd)/quagga-config
mkdir -p ${QUAGGA_CONFIG}

Configure your router instance

This uses the configuration generated from the course website. The argument given is your router name for the tutorial. In the example F is used.

docker run \
  --volume ${QUAGGA_CONFIG}:/etc/quagga \
  alectolytic/quagga-bgp-tutorial bgpexpert-configure F

Run bgpd and zebra

docker run \
  --detach \
  --volume ${QUAGGA_CONFIG}:/etc/quagga \
  --publish 179:179 \
  --publish 2605:2605 \
  alectolytic/quagga-bgp-tutorial

Connect to the container

telnet localhost 2605

Stopping the container

To stop, identify the container id, then stop it.

$ docker ps
CONTAINER ID        IMAGE                COMMAND                CREATED             STATUS              PORTS                                          NAMES
a0c599f711e0        ralectolytic/quagga-bgp-tutorial:latest   "/usr/bin/supervisor   8 seconds ago       Up 7 seconds        0.0.0.0:179->179/tcp, 0.0.0.0:2605->2605/tcp   backstabbing_tesla
$ docker stop a0c599f711e0

Launching multiple instances

To do this we create three configuration directories, and configure routers with different ids then start them. Note that we do not map the ports explicitly here.

export QUAGGA_CONFIG=$(pwd)/quagga

for NAME in A B C; do
    mkdir -p ${QUAGGA_CONFIG}.${NAME}
    docker run \
        --volume ${QUAGGA_CONFIG}.${NAME}:/etc/quagga \
        alectolytic/quagga-bgp-tutorial bgpexpert-configure ${NAME}
    docker run \
        --detach \
        --volume ${QUAGGA_CONFIG}:/etc/quagga \
        --publish 179 \
        --publish 2605 \
        alectolytic/quagga-bgp-tutorial
done

Identifying host ports
