無法讓 Docker 中的 Cassandra 與集群通信

嘗試使用官方 docker 映像讓 Cassandra 在 docker 中執行。當我執行以下程式碼行時，它會啟動然後停止 docker 而不連接到集群。我檢查了該cassandra.yaml文件，它看起來就像我集群上的其他節點一樣。文件也一樣cassandra-rackdc.properties。docker 可以 ping 所有其他電腦。

我執行以下和一些推導：

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

我收到以下錯誤：

我認為問題可能是您沒有設置CASSANDRA_BROADCAST_ADDRESSCassandra 在與其他節點通信時使用的參數。預設情況下，它將其設置為值CASSANDRA_LISTEN_ADDRESS，但在您的情況下，此地址是 Docker 網路的地址，因此其他節點將無法訪問您的 Docker 實例。

您需要設置CASSANDRA_BROADCAST_ADDRESS託管 Docker 的機器的 IP 地址。
