# Cluster leader election using Consul distributed locks
```go
package main
import (
"log"
"time"
"github.com/hashicorp/consul/api"
"github.com/pteich/clusterleader"
)
func main() {
config := api.DefaultConfig()
config.Address = "127.0.0.1:8500"
client, err := api.NewClient(config)
clusterLeader, err := clusterleader.NewClusterleader(client, "testkey", "localhost", 15*time.Second)
if err != nil {
log.Fatal(err)
}
go func() {
for err := range clusterLeader.Errors() {
log.Print(err)
}
}()
// as long as this loop runs we try to become leader
// an isElected event is send on every state change
// best would be to run this loop in a go routine and
// react to whatever we are leader or not
for isElected := range clusterLeader.Election() {
if isElected {
// we are leader
} else {
// not leader
}
}
}
