Make sure you are generating image from a Dockerfile uses the below docker commands: Stop running containers: To clean your host from all containers and images use the following bash script: Here is a video on how to launch the lab: Note that GNS3 topology is already configured for IPv6, so as soon as you start the routers, Docker containers will be assigned IPv6 addresses from the routers through SLAAC (Stateles Auto Configuration) which makes them reachable through IPv6. Sudo pipework br7 -i eth1 $FIREFOX_C1 we end up with the following conainers: IMGLIST="$(sudo docker images | grep mybimage | awk '')" Sudo pipework -i avoid manipulating image id’s and container id’s for each of the images and the containers, I use a bash script to build and run all containers automatically: The parameters of this command may differ slightly for each GUI containers.Ĭreate host bridge interface and link to a new interface inside the container, assign to it an IP and a new default gateway. Spawn and run a writable container with interactive console. Here is the general workflow for each container. This is how containers are built for this lab: A docker container instance based upon a simple ubuntu, on top of which (as separate image) we install firefox ( ).A docker container instance based upon the first built image (1), on top of which (as separate image) we install apache ( ).On top of which (as separate image) we install some linux tools like wget, iperf, inetutils-traceroute, iputils-tracepath, mtr, dnsutils, sipp, pjsua. Two docker container instances based upon a special minimal ubuntu image modified for docker ( ).To demonstrate docker flexibility, we will use 4 docker containers with 4 different subnets: How pipework connects exposes container network Lab requirements:įor each container, we will generate docker image, run a container with an interactive terminal and set networking parameters (IP and default gateway).
