How to set up cqlsh to interact with Cassandra Docker

Did you know that cqlsh is a CLI command-line interface for interacting with Cassandra via CQL?

It is shipped with every Cassandra package. We can find it in the bin/directory with the Cassandra executable.

We can set up cqlsh to interact with Cassandra using Docker with these steps:

1. First, we can download and install Docker from the official Docker website.
2. Then, we have to pull the Cassandra Docker image with this command:

   docker pull cassandra
3. After that, we can start a Cassandra container with this command:

   docker run --name new-cassandra -p 9042:9042 -d cassandra

   This command will start a Cassandra container named new-cassandra and maps the container’s default Cassandra port to the same port on our host machine.
4. Once the Cassandra container starts, we can monitor the logs by running:

   docker logs -f my-cassandra

   We have to wait until we see a log entry telling us that Cassandra has started successfully.
5. After Cassandra is running, we can start a cqlsh session with this command:

   docker exec -it my-cassandra cqlsh

   This command gives us an interactive shell to execute CQL queries.

Furthermore, we can exit the cqlsh session by typing exit in the terminal.

Additionally, we can stop and remove the Cassandra container, with these commands:

docker stop my-cassandra
docker rm my-cassandra
