Running Single Node Cassandra Container

Run the cassandra container with docker-compose

Pre-requisites:

• docker
• docker compose

cassandra single node docker-compose

• Create the directory cassandra && cd cassandra
• Pull the required verison image docker pull cassandra:5.0
• Create the .env file in the above directory with the following content:

VERSION=5.0

• Create the file docker-compose.yml in the above directory with the following content:

networks:
  cassandra:
services:
  cassandra:
    image: cassandra:${VERSION:-5.0}
    container_name: cassandra
    hostname: cassandra
    healthcheck:
        test: ["CMD", "cqlsh", "-e", "describe keyspaces" ]
        interval: 5s
        timeout: 5s
        retries: 60
    networks:
      - cassandra
    ports:
      - "9042:9042"
    volumes:
      - ./data:/var/lib/cassandra
    environment: 
        CASSANDRA_CLUSTER_NAME: SolarSystem
        CASSANDRA_DC: Mars
        CASSANDRA_RACK: West
        CASSANDRA_ENDPOINT_SNITCH: GossipingPropertyFileSnitch
        CASSANDRA_NUM_TOKENS: 128

• Run the command docker-compose up -d
• Check the status of the container: docker ps -a, you will see a container running with

CONTAINER ID   IMAGE           COMMAND                  CREATED         STATUS                   PORTS                                                       NAMES
860be3abecf9   cassandra:5.0   "docker-entrypoint.s…"   4 minutes ago   Up 4 minutes (healthy)   7000-7001/tcp, 7199/tcp, 9160/tcp, 0.0.0.0:9042->9042/tcp   cassandra

• Check with the logs docker logs cassandra | grep "9042", you will see the container logs with following, then your container is ready for use:

INFO  [main] 2024-06-09 04:22:32,346 PipelineConfigurator.java:131 - Starting listening for CQL clients on /0.0.0.0:9042 (unencrypted)...
INFO  [main] 2024-06-09 04:22:32,353 CassandraDaemon.java:738 - Startup complete

• SSH into container to interact with cqlsh: docker exec -it cassandra bash
• Run the command cqlsh
