How to make below 5 members can be elected as leader to all pods rather than only one pod

[ningyougang]

func main() {

    // initialize the client
    etcdClient, err := client.New(client.Config{Endpoints: []string{"localhost:2379"}})
    if err != nil {
        log.Fatal(err)
    }
    defer etcdClient.Close() // cleanup

    // create a new session for leader election
    electionSession, err := concurrency.NewSession(etcdClient, concurrency.WithTTL(5))
    if err != nil {
        log.Fatal(err)
    }
    defer electionSession.Close() // cleanup

    members := 5
    for i := 0; i < members; i++ {
        go func(i int) {
            election := concurrency.NewElection(electionSession, fmt.Sprintf("/election-prefix/%d", i))
            ctx := context.Background()

            fmt.Println(fmt.Sprintf("[index: %d] Attempting to become a leader", i))
            // start leader election
            if err := election.Campaign(ctx, "e"); err != nil {
                log.Fatal(err)
            }
            fmt.Println(fmt.Sprintf("[index: %d] become a leader", i))
        }(i)
    }

    for {
        // forever loop prevents our program from ending
    }
}

Let's assume the pod started order is pod1 -> pod2 -> pod3

• At the very beginning, all memembers in pod1 will become leader
• If shutdown pod1, all memembers in pod2 will become leader
  • After shutdown pod1, another new pod4 will be created
• If shutdown pod2, all memembers in pod3 will become leader
• if shutdown pod3, all memembers in pod4 will become leader

It seems are members will become leader in one same pod which the pod that first executes this election.Campaign method
I want to the leaders can be distributed to pod2/pod3/pod4 both if pod1 is shutdown, has any idea?
