CassandraLauncher 1.18-5

Command-line utilities for launching Cassandra clusters in EC2
CassandraLauncher is a project that has two offerings:

1. Cassandra Launcher - An easy to use, interactive command line interface that allows you to deterministically launch a DataStax Community or DataStax Enterprise cluster in under a minute. This component also comes with a fully scriptable interface for cluster launches straight from the command line.
2. Cluster Launcher - A great tool that combines both Amazon's EC2 and Rackspace's Cloudservers into a single tool that allows for deterministicly easy clustering, keyless ssh, and interactive prompts for choosing your environment. No longer must you search for images IDs or wait past page reloads for a cluster since this is all done on the client side.

Installation

Make sure python-setuptools and python-pip are installed, then run:

pip install cassandralauncher

or if installing from source:

python setup.py build
python setup.py install


Setup

Choose one of these things. They are checked by the programs in this order:

- Add export CLUSTERLAUNCHER_CONF= to your ~/.bash_profile or ~/.profile.
- Open clusterlauncher.conf in your git checkout repo.
- Copy clusterlauncher.conf to ~/.clusterlauncher.conf.
- Open /etc/cassandralauncher/clusterlauncher.conf.

Edit clusterlauncher.conf with your authentication parameters.

EC2/RAX Plain Cluster Launcher

To destroy

Either run cassandralauncher or clusterlauncher again.

- With cassandralauncher:

- Select Cluster, Confirm.

- With clusterlauncher:

- Select EC2 or RAX, Destroy, Cluster, Confirm.

THIS MUST BE DONE! IF NOT YOUR AWS ACCOUNT WILL GET A HUGE BILL. TAKE IT FROM ME!

Disclaimer: Even though these tools try their best to keep track of launched clusters, it is always best to ensure that all clusters are terminated periodically. This is especially true in cases where AWS/RAX was unable to tag the machine as they were launched. If the tools were unable to tag said machines, they will forever ignore them since we would rather not even present the option to kill a cluster these tools did not launch.

Programmatically Launching Cassandra Clusters

Run:

cassandralauncher -h

to display all options. clusterlauncher does not have this functionality, but is easily scriptable at the Python level calling ec2.py or rax.py. See clusterlauncher.py for how to do this.
