Я использую Docker для Windows 10. Я пытался подключиться к своему локальному хосту, но выдает ошибку.Я использовал команду> docker start cassandra-ce ..., которая успешна, но когда я запускаю команду 'sbt run' и ввел свой localhost: 9000 в браузере, это выдает ошибку:

Я также изменил свойapplication.conf 

application.baseUrl="http://localhost:9000"
ce.webserver.url="http://localhost:8100"
ce.cassandra.host="localhost"
version=33

и мой файл persistance.xml для localhost и порта 9160: 

<properties>
            <property name="kundera.nodes" value="localhost" />
            <property name="kundera.port" value="9160" />
            <property name="kundera.keyspace" value="cedb" />
            <property name="kundera.dialect" value="cassandra" />
            <property name="kundera.ddl.auto.prepare" value="update" />
            <property name="kundera.client.lookup.class" value="com.impetus.client.cassandra.thrift.ThriftClientFactory" />
        </properties>

Это потому, что вы не сделали отображение портов при запуске Cassandra в Docker.Ваш Cassandra виден только в этой конкретной сети докеров.Используйте следующую команду, чтобы запустить Cassandra с сопоставлением портов.

docker run -p 9042:9042 cassandra

Тогда вы увидите 0.0.0.0:9042->9042/tcp in docker ps

Для второй ошибки, если вы не хотите автоматически управлять схемой, измените порт <property name="kundera.port" value="9160" /> на 9042 и удалите<property name="kundera.ddl.auto.prepare" value="update" />

Если вы хотите автоматически управлять схемой, измените порт <property name="kundera.port" value="9160" /> на 9042 и используйте следующую команду, чтобы запустить Cassandra в докере, запускающем сервер управления Cassandra и сопоставление портов с портом управления. 

docker run -p 9042:9042 -p 9160:9160 -e CASSANDRA_START_RPC=true cassandra
