Cassandra in Docker

This repository provides everything you need to run Cassandra in Docker, and is tuned for fast container startup.

Why?

While naive Cassandra images take around 30 seconds to start, our containers take only a few seconds. Optimizations include:

• Disabling vnodes. We don't use them at Spotify, and Cassandra starts much faster without them (~10 sec).
• Disabling something called "waiting for gossip to settle down" because there is no gossip in a one-node cluster (another ~10 sec).

In the box

• argussecurity/cassandra

  This is probably the image you want, it runs a one-node Cassandra cluster. Built from the cassandra directory0

• argussecurity/cassandra:cluster

  Runs a Cassandra cluster. Expects CASSANDRA_SEEDS and CASSANDRA_TOKEN env variables to be set. If CASSANDRA_SEEDS is not set, node acts as its own seed. If CASSANDRA_TOKEN is not set, the container will not run. Built from the cassandra-cluster directory.

• argussecurity/cassandra:cluster-prometheus

  Same as argussecurity/cassandra:cluster, with an added javaagent to export metrics to Prometheus. Config is taken from https://github.com/prometheus/jmx_exporter/blob/master/example_configs/cassandra.yml.

  (Default Prometheus' JMX Exporter port: 31500. To override, set PROMETHEUS_PORT environment variable.)

• argussecurity/cassandra:base

  The base image with an unconfigured Cassandra installation. You probably don't want to use this directly. Built from the cassandra-base directory.

Notes

Things are still under heavy development:

• Only Cassandra 2.0 with almost-generic config (miles away from what we actually run Cassandra with) is supported so far.
• There's nothing to help you with tokens and stuff.
