apache-cassandra-4.0.7 Dockerfile 不可用异常

Question

尝试从 apache-cassandra-4.0.7-bin.tar.gz 创建 docker 映像，但在配置密钥空间后出现以下错误

$ docker exec -it pidcss /bin/bash

$ ./cqlsh localhost -u cassandra -p cassandra

Connected to Test Cluster at localhost:9042

[cqlsh 6.0.0 | Cassandra 4.0.7 | CQL spec 3.4.5 | Native protocol v5]

Use HELP for help.

cassandra@cqlsh> CREATE KEYSPACE pid
   ...   WITH REPLICATION = { 
   ...    'class' : 'SimpleStrategy', 
   ...    'replication_factor' : 0 
   ...   };
cassandra@cqlsh> use pid
   ... ;
cassandra@cqlsh:pid> CREATE TABLE if not exists vis (parentid text, type text,  PRIMARY 
KEY (parentid));

cassandra@cqlsh:pid> describe tables;

有什么想法可以帮助解决这个问题。

谢谢，

尚不清楚 docker 镜像是否已成功拉取并设置正确。从高层次来看，这些步骤看起来像，

• docker pull cassandra:4.0.11

  或使用来自

  https://hub.docker.com/_/cassandra/tags?page=1

  的最新标签 docker pull cassandra:latest

• docker network create cassandra

• docker run --rm -d --name cassandra --hostname cassandra --network cassandra cassandra

  并让它完全启动

• docker run --rm -it --network cassandra nuvo/docker-cqlsh cqlsh cassandra 9042 --cqlversion='3.4.5'

  启动交互式 CQLSHell

（可选的清理活动）

docker kill cassandra
docker network rm cassandra

希望有帮助！
