无法让 Docker 中的 Cassandra 与集群通信

  • 772

尝试使用官方 docker 映像让 Cassandra 在 docker 中运行。当我执行以下代码行时，它会启动然后停止 docker 而不连接到集群。我检查了该cassandra.yaml文件，它看起来就像我集群上的其他节点一样。文件也一样cassandra-rackdc.properties。docker 可以 ping 所有其他计算机。

我运行以下和一些推导：

docker run --name cassandra -i \
-v /media/mcamp/HDD/Docker/CampgroundContainer1:/var/lib/cassandra \
-e CASSANDRA_SEEDS="192.168.0.114, 192.168.0.101, 192.168.0.106" \
-e CASSANDRA_CLUSTER_NAME=CampCluster \
-e CASSANDRA_DC=campground-wireless \
-e CASSANDRA_RACK=Docker1 \
-e CASSANDRA_ENDPOINT_SNITCH=GossipingPropertyFileSnitch \
-e CASSANDRA_START_RPC=true \
-e CASSANDRA_LISTEN_ADDRESS=172.17.0.2 \
-p 7000:7000 \
 cassandra:latest

我收到以下错误：

    我认为问题可能是您没有设置CASSANDRA_BROADCAST_ADDRESSCassandra 在与其他节点通信时使用的参数。默认情况下，它将其设置为值CASSANDRA_LISTEN_ADDRESS，但在您的情况下，此地址是 Docker 网络的地址，因此其他节点将无法访问您的 Docker 实例。

    您需要设置CASSANDRA_BROADCAST_ADDRESS托管 Docker 的机器的 IP 地址。
