%description
    Consul is a tool for service discovery and configuration in a
    cluster of machines. Consul is distributed, highly available, and
    extremely scalable. Consul provides several key features: Service
    Discovery (via REST or DNS interfaces), Health Checking, Key/Value
    Storage and Multi-Datacenter Support. It is internally based on the
    excellent RAFT consensus protocol and the SWIM gossip/membership
    protocol.
