Unable to create new session

[adi-kmt]

I'm running the docker command docker run --name some-scylla -d scylladb/scylla:5.2.0 --smp 2 --memory 200MB --developer-mode 1

When I try cqlsh it says connected to 172.17.0.2:9042. But when I try

SELECT peer, preferred_ip, rpc_address FROM system.peers; peer | preferred_ip | rpc_address ------+--------------+-------------

So completely empty.

When I try to run

retryPolicy := &gocql.ExponentialBackoffRetryPolicy{
		Min:        time.Second,
		Max:        30 * time.Second,
		NumRetries: 5,
	}
	cluster := gocql.NewCluster("172.17.0.2")
	cluster.Keyspace = keyspace
	cluster.Timeout = 2 * time.Minute
	cluster.RetryPolicy = retryPolicy
	cluster.Consistency = consistency
	cluster.ProtoVersion = 4
	// cluster.Port = 9042
	cluster.Authenticator = gocql.PasswordAuthenticator{
		Username: "cassandra",
		Password: "cassandra",
	}

session, err := gocql.NewSession(*cluster)

And it fails at this point Have tried changing config as much as I can from stackoverflow posts, but not getting it to work

Error is

2024/07/18 16:46:04 gocql: unable to dial control conn 172.17.0.2:9042: dial tcp 172.17.0.2:9042: i/o timeout
