Monitor

1. /metrics - use metrics endpoint to get info about replica state,
2. Bully election dashboard - web app for monitoring entire cluster.

Build

make build # to build locally.
make test # to run all tests.
make build-image # to build Docker image.

Deploy

make deploy # to deploy in Kubernetes cluster.

Limitations

1. sometimes cluster selects wrong leader on deployment creation,
2. when number of pods is high (>=20) there may be several leaders selected.
