Simple

This example creates a member per process, where each member joins the cluster, periodically updates its local state with random entries, and logs the received updates.

Running

Create a member per process with flags:

• -addr: Address to listen on
• -join: Addresses of existing members to join

Such as to create a three node cluster:

go run examples/simple/main.go -addr :7000
go run examples/simple/main.go -addr :7001 -join localhost:7000
go run examples/simple/main.go -addr :7002 -join localhost:7000

Each member will gracefully leave the cluster on SIGINT or SIGTERM signals. You can also forcefully terminate a node with SIGKILL which won't leave gracefully but exits immediately so the other nodes will detect it as failed.

To expose Prometheus metrics, configure the metrics server address with -metrics-addr. This will expose the Prometheus metrics at http://{addr}/metrics.
