Hold my Lease

A simple, distributed lease system based on the RAFT consensus protocol.

Get Started

This work relies on using raftadmin to setup and manage a RAFT cluster.

Compiling Protos

make compile

Building

make build

This will create a binary hml in the project root.

Starting Nodes

For demonstration, we'll start a locally running cluster made up of three nodes.

./hml --raft_bootstrap --raft_id=1 --address=localhost:50061
./hml --raft_id=2 --address=localhost:50062
./hml --raft_id=3 --address=localhost:50063

Add Voters

raftadmin --leader multi:///localhost:50061,localhost:50062 add_voter 2 localhost:50063 0
raftadmin --leader multi:///localhost:50061,localhost:50062 add_voter 3 localhost:50063 0
raftadmin --leader multi:///localhost:50061,localhost:50062,localhost:50063 leadership_transfer
