Docker image for counting rows in a Cassandra table

Cassandra Count Docker

This is a Docker image for counting rows in a Cassandra table. It uses the great cassandra-count command line tool by brianmhess.

Currently it only supports to set the host and port of the Cassandra instance as well as the table name to request and its corresponding keyspace. These parameters are set via environment variables. Usage from Docker is as follows:

docker pull soerenhenning/cassandra-count
docker run --rm --name cassandra-count -e "CASSANDRA_HOST=localhost" -e "CASSANDRA_PORT=9042" -e "KEYSPACE=my-keyspace" -e "TABLE=my-table" --network host soerenhenning/cassandra-count

The configuration for --network depends on the context your Cassandra instance is deployed in.

Kubernetes

Usage in Kubernetes is straightforward:

kubectl run cassandra-count --rm --attach --restart=Never --image=soerenhenning/cassandra-count --env "CASSANDRA_HOST=cassandra" --env "CASSANDRA_PORT=9042" --env "KEYSPACE=my-keyspace" --env "TABLE=my-table"
