BOSH release to run cassandra

Background

What is cassandra?

cassandra aggregates events from your servers and applications with a powerful stream processing language. Send an email for every exception in your app. Track the latency distribution of your web app. See the top processes on any host, by memory and CPU. Combine statistics from every Riak node in your cluster and forward to Graphite. Track user activity from second to second.

Usage

To use this bosh release, first upload it to your bosh:

bosh upload release https://github.com/hybris/cassandra-boshrelease

For bosh-lite, you can quickly create a deployment manifest & deploy a cluster:

templates/make_manifest warden
bosh -n deploy

For AWS EC2, create a single VM:

templates/make_manifest aws-ec2
bosh -n deploy

Override security groups

For AWS & Openstack, the default deployment assumes there is a default security group. If you wish to use a different security group(s) then you can pass in additional configuration when running make_manifest above.

Create a file my-networking.yml:

---
networks:
  - name: cassandra1
    type: dynamic
    cloud_properties:
      security_groups:
        - cassandra

Where - cassandra means you wish to use an existing security group called cassandra.

You now suffix this file path to the make_manifest command:

templates/make_manifest openstack-nova my-networking.yml
bosh -n deploy
