The multidim interop tests use random high ports for listeners. Since you need to know which port will be listened on ahead of time to EXPOSE a port in a Docker image to the host machine, this means everything has to be run in Docker.

This must be repeated every time you make a change to the js-libp2p source code.

$ npm run build
$ docker build . -f ./interop/Dockerfile -t js-libp2p-node

$ npm run build
$ docker build . -f ./interop/BrowserDockerfile -t js-libp2p-browsers

1. Clone the test-plans repo somewhere

   $ git clone https://github.com/libp2p/test-plans.git

2. (Optional) If you are running an M1 Mac you may need to override the build platform.
   • Edit /transport-interop/dockerBuildWrapper.sh
   • Add --platform linux/arm64/v8 to the docker buildx build command

     docker buildx build \
       --platform linux/arm64/v8 \    <-- add this line
       --load \
       -t $IMAGE_NAME $CACHING_OPTIONS "$@"
     

3. (Optional) Enable some sort of debug output
   • nim-libp2p
     • edit /transport-interop/impl/nim/$VERSION/Dockerfile
     • Change -d:chronicles_log_level=WARN to -d:chronicles_log_level=DEBUG
   • rust-libp2p
     • When starting the docker container add -e RUST_LOG=debug
   • go-libp2p
     • When starting the docker container add -e GOLOG_LOG_LEVEL=debug
4. Build the version you want to test against

   $ cd multidim-interop/impl/$IMPL/$VERSION
   $ make
   ...

Redis is used to allow inter-container communication, exchanging listen addresses etc. It must be started as a Docker container:

$ docker run --name redis --rm -p 6379:6379 redis:7-alpine

$ docker run -e transport=tcp -e muxer=yamux -e security=noise -e is_dialer=true -e redis_addr=redis:6379 --link redis:redis js-libp2p-node

$ docker run -e transport=webtransport -e muxer=yamux -e security=noise -e is_dialer=true -e redis_addr=redis:6379 --link redis:redis js-libp2p-browsers

• Change go-v0.29 to the implementation you wish to use.
• Ensure one docker run has is_dialer=false and the other has is_dialer=true
• Ensure the transport option is the same for both implementations

$ docker run -e transport=tcp -e muxer=yamux -e security=noise -e is_dialer=false -e redis_addr=redis:6379 --link redis:redis go-v0.29
