docker-无法从主机连接到cassandra

Docker 前端之家
前端之家收集整理的这篇文章主要介绍了docker-无法从主机连接到cassandra ，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

我已经在我的Mac Book Pro上使用docker配置了一个cassandra节点,如下所示

VBoxManage modifyvm "default" --natpf1 "tcp-port7191,tcp,7191,7191"
VBoxManage modifyvm "default" --natpf1 "tcp-port7000,7000,7000"
VBoxManage modifyvm "default" --natpf1 "tcp-port7001,7001,7001"
VBoxManage modifyvm "default" --natpf1 "tcp-port9160,7160,7160"
VBoxManage modifyvm "default" --natpf1 "tcp-port9042,9042,9042"

(重启机器)

docker run --name c1 -v /Users/MyProjects/scripts/:/script -d cassandra:latest -p "7191:7191" -p "7000:7000" -p "7001:7001" -p "9160:9160" -p "9042:9042"

我可以轻松做到

docker exec -it c1 cqlsh

它说

Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 3.0.1 | CQL spec 3.3.1 | Native protocol v4]
Use HELP for help.

现在我使用以下方式获取虚拟机虚拟机的IP地址

docker-machine env default

我可以看到IP地址192.168.99.100

但是,当我运行Java程序以使用上述IP地址连接到同一cassandra实例时.我得到一个错误

这是我配置Java连接的代码

Cluster.builder()
  .addContactPoints("192.168.99.100").withPort(9042)
  .build()

编辑：我也用docker guest虚拟机VM的IP地址替换了上面的IP地址…但是那不能解决问题.

最佳答案
创建Docker容器时,我可以通过使用CASSANDRA_BROADCAST_ADDRESS解决问题

这是我使用的命令

docker run --name c1 -v /Users/MyProjects/scripts/:/script -d -p "7191:7191" 
-p "7000:7000" -p "7001:7001" -p "9160:9160" -p "9042:9042" -e 
CASSANDRA_BROADCAST_ADDRESS=192.168.99.100 cassandra:latest

这样创建容器之后.我可以使用以下代码从我的Scala应用程序进行连接

  val keyspace: KeySpace = new KeySpace("foo")

  val cluster =
    Cluster.builder()
      .addContactPoint("192.168.99.100").withPort(9042)
      .build()

  cluster.getConfiguration().getSocketOptions().setReadTimeoutMillis(100000);
  val session: Session = cluster.connect(keyspace.name)
