Building the image

You can build the docker image by running:

make build

To start the image, simply run:

make start

Connect to the container

docker exec -it ns3 bash

Testing the image

To make sure that it works, in the container run:

1. cd ns-allinone-3.37/ns-3.37/
2. cp examples/tutorial/second.cc scratch/
3. ./ns3 scratch/second

Expected output:

root@ubuntu20:/usr/ns-allinone-3.37/ns-3.37# ./ns3 run scratch/second
