Go 可以'；t从主机连接到ScyllaDB容器

我刚刚try 使用Golang从本地计算机连接到Docker Desktop上启动的3 node Scylla集群，但没有成功(在Mac M2上)

我试着遵循下面的步骤:https://university.scylladb.com/courses/using-scylla-drivers/lessons/golang-and-scylla-part-1/

例外是我没有为测试应用程序创建停靠容器，因为我不想在任何时候修改代码时重新创建容器.我现在想在本地进行测试.

Docker-组合零件

services:
  scylla-node1:
    image: scylladb/scylla:latest
    restart: always
    container_name: scylla-node1
    command: --seeds=scylla-node1,scylla-node2 --smp 1 --memory 750M --overprovisioned 1 --api-address 0.0.0.0
    volumes:
      - './scylla/scylla.yaml:/etc/scylla/scylla.yaml'
      - './scylla/cassandra-rackdc.properties.dc1:/etc/scylla/cassandra-rackdc.properties'
      - './scylla/mutant-data.txt:/mutant-data.txt'
    networks:
      - myappnetwork

  scylla-node2:
    image: scylladb/scylla:latest
    restart: always
    container_name: scylla-node2
    command: --seeds=scylla-node1,scylla-node2 --smp 1 --memory 750M --overprovisioned 1 --api-address 0.0.0.0
    volumes:
      - './scylla/scylla.yaml:/etc/scylla/scylla.yaml'
      - './scylla/cassandra-rackdc.properties.dc1:/etc/scylla/cassandra-rackdc.properties'
    networks:
      - myappnetwork

  scylla-node3:
    image: scylladb/scylla:latest
    restart: always
    container_name: scylla-node3
    command: --seeds=scylla-node1,scylla-node2 --smp 1 --memory 750M --overprovisioned 1 --api-address 0.0.0.0
    volumes:
      - './scylla/scylla.yaml:/etc/scylla/scylla.yaml'
      - './scylla/cassandra-rackdc.properties.dc1:/etc/scylla/cassandra-rackdc.properties'
    networks:
      - myappnetwork

networks:
  myappnetwork:
    driver: bridge

那么，I created the keyspace and data as explained in the tutorial

并try 连接gocql:

// go.mod

go 1.21.0

replace github.com/gocql/gocql => github.com/scylladb/gocql v1.11.1

import (
  ...
  "github.com/gocql/gocql"
)

func Start(log logger.Logger) {
    config := CreateCluster(gocql.Quorum, "catalog", "scylla-node1", "scylla-node2", "scylla-node3")
    // config := CreateCluster(gocql.Quorum, "catalog", "172.29.0.5", "172.29.0.4", "172.29.0.3")
    // >>> doesn't work either cause I can't even ping containers IPs
    session, err := gocql.NewSession(*config)
    if err != nil {
        log.Fatal(err, "db", "Start", "unable to connect to scylla")
    }
    defer session.Close()
}

func CreateCluster(consistency gocql.Consistency, keyspace string, hosts ...string) *gocql.ClusterConfig {
    retryPolicy := &gocql.ExponentialBackoffRetryPolicy{
        Min:        time.Second,
        Max:        10 * time.Second,
        NumRetries: 5,
    }
    config := gocql.NewCluster(hosts...)
    config.PoolConfig.HostSelectionPolicy = gocql.TokenAwareHostPolicy(gocql.RoundRobinHostPolicy())
    config.Compressor = &gocql.SnappyCompressor{}
    config.RetryPolicy = retryPolicy
    config.Timeout = 5 * time.Second

    config.Keyspace = keyspace
    config.Consistency = consistency

    return config
}
