Help Wanted: Simple Cassandra Sample

I am putting together simple samples for various database tools and software (only official docker images at this time). Does anyone have enough experience with Cassandra to provide a simple pipeline that is able to start and ping a Cassandra database service, using the official Cassandra images? Ideally something similar to this Mongo example:

kind: pipeline
name: default

steps:
- name: ping
  image: mongo:4
  commands:
  - sleep 5
  - mongo --host mongo --eval "db.version()"

services:
- name: mongo
  image: mongo:4
  command: [ --smallfiles ]

or similar to this postgres example:

---
kind: pipeline
name: default

platform:
  os: linux
  arch: amd64

steps:
- name: test
  image: postgres:9-alpine
  commands:
  - sleep 10
  - psql -U postgres -d test -h database -c "SELECT version();"

services:
- name: database
  image: postgres
  environment:
    POSTGRES_DB: test
    POSTGRES_USER: postgres
