You need to have go and protobuf installed system-wide to make this compile (e.g. on Archlinux, sudo pacman -S go protobuf).
You need also to install the go protobuf plugin with the command go get -u github.com/golang/protobuf/protoc-gen-go.
Finally, install the go dependencies by doing go get -u inside of the project repository.
To build this program, you need to run the build.sh file, which will make a main.run executable file.
To use you can either start the node alone ./main.run, or with an ip to make it join an existing network /main.run <ip>.
To build the docker image, run the command sudo docker build . -t kademlia.
To start it, run the command either as a starting node by using sudo docker run -p 8080:8080 -p 9090:9090 kademlia
or as a joining node by using sudo docker run -p 8080:8080 -p 9090:9090 kademlia ./main.run <IP>.
To run as a cluster, start by initializing a swarm with sudo docker swarm init.
To start a swarm run sudo docker stack deploy --compose-file docker-compose.yml kademlia from the base of the folder.
To remove a swarm run sudo docker service rm kademlia_nodes kademlia_entry_node.
Output from nodes can viewed with sudo docker service logs kademlia_nodes --raw.
To contact API of node, run ip addr and seach for the interface named docker_gwbridge and use the address your computer took on it.
E.G. if this address is 172.18.0.1 the entry is on 172.18.0.1:8080 and the loadbalancer over the 50 other is on 172.18.0.1:8081.
