This repo has git submodules dependencies, so in order to properly work, you need to clone it by doing:
git clone --recurse-submodules -j8 [email protected]:octaviotastico/dtn-emulator.git
If you already cloned the repo without using the recurse submodules flag, or you have an older version of Git, you can use:
git submodule update --init --recursive
docker build --pull --rm -f "Dockerfile" -t ud3tn "."
docker run --rm -it -p <AAP PORT Number>:8000 -p <CLA PORT Number>:8001 ud3tn:latest
For example:
docker run --rm -it -p 4242:8000 -p 4224:8001 ud3tn:latest
docker run --rm -it -p 4243:8000 -p 4225:8001 ud3tn:latest
docker run --rm -it -p 5555:8000 -p 6666:8001 ud3tn:latest
etc...
docker ps -a
docker exec -it <container id> bash
To do this, you can either use host networking (basically removing network isolation), or to create a Docker network (a bridge).
The easiest way is to use your own network (host networking).
docker run --rm -it --network host ud3tn:latest
And that's all for host networking.
If you want to isolate the Docker container, you can still use bridge networking.
docker network list
docker network create DTN-test-network
If container was already created, you can connect it later by doing:
docker network connect DTN-test-network <container id>
If container was not already created, you can create it connected to the new docker network by doing:
docker run --rm -it --net DTN-test-network -p 4242:8000 -p 4224:8001 ud3tn:latest
All you have to do is to add the --net DTN-test-network flag.
And check its IP Address, ports, and which network is it connected to:
docker inspect <container name>
If we were to create a DTN with two nodes, Node A and Node B, we could launch two different containers and do something like this:
ud3tn/build/posix/ud3tn --eid dtn://a.dtn/ --bp-version 7 --aap-port 4242 --cla "mtcp:*,4224"
ud3tn/build/posix/ud3tn --eid dtn://b.dtn/ --bp-version 7 --aap-port 4243 --cla "mtcp:*,4225"
python3 ud3tn/tools/aap/aap_config.py --tcp localhost 4242 --dest_eid dtn://a.dtn/ --schedule 1 3600 100000 dtn://b.dtn/ mtcp:localhost:4225
python3 ud3tn/tools/aap/aap_config.py --tcp localhost 4243 --dest_eid dtn://b.dtn/ --schedule 1 3600 100000 dtn://a.dtn/ mtcp:localhost:4224
python3 ud3tn/tools/aap/aap_send.py --tcp localhost 4242 dtn://b.dtn/bundlesink 'Hello, from node A!'
python3 ud3tn/tools/aap/aap_send.py --tcp localhost 4243 dtn://a.dtn/bundlesink 'Hello, from node B!'
