Trying to create docker image from apache-cassandra-4.0.7-bin.tar.gz but getting following error after configring keyspace

$ docker exec -it pidcss /bin/bash

$ ./cqlsh localhost -u cassandra -p cassandra

Connected to Test Cluster at localhost:9042

Any idea on what could help resolve this.

Thanks,

Solution

  • It is unclear if the docker image got pulled successfully & set up correct. At a high level the steps would look like,

    (Optional clean-up activities)

    docker kill cassandra
docker network rm cassandra

    I hope that helps!
