aims to provide a user-friendly command line tool to create, manage and setup computing clusters hosted on cloud infrastructures like Amazon's Elastic Compute Cloud EC2, Google Compute Engine, or a private OpenStack cloud. Its main goal is to get your compute cluster up and running with just a few commands.
The architecture of ElastiCluster is quite simple: a configuration file defines a set of cluster configurations and information on how to access a specific cloud webservice.
Using the command line (or, very soon, a simple API), you can start a cluster. ElastiCluster will connect to the desired cloud, start the virtual machines and wait until they are accessible via SSH.
After all the virtual machines are up and running, ElastiCluster will use Ansible to configure them.
ElastiCluster provides automated setup of:
ElastiCluster is in active development, and offers the following features at the moment:
The following sample shows how a cluster is configured with ElastiCluster and the basic commands to interact with ElastiCluster through the command line interface. For a full description of the configuration and command line interface see the documentation. It's also possible to bundle all the examples below in a single configuration file.
This example shows how to set up a SLURM batch-queuing cluster with 4 compute nodes and a single front-end node (also acting as NFS server for shared home directories). More details on the SLURM configuration can be found here.

$ elasticluster stop mycluster
This example shows how to set up a Hadoop 2.x cluster, complete with HDFS. Each of the 8 "worker" nodes are both HDFS data nodes and YARN execution nodes. The single "master" node acts as YARN resource manager and HDFS name node.
Spark (together with Python and R support) is installed on top of Hadoop YARN; as soon as the cluster is installed, it is possible to log in to the "master" node and start submitting Spark or Map/Reduce jobs.
More details on the Hadoop/Spark configuration can be found here.

$ elasticluster sftp cluster1
$ elasticluster stop cluster1 cluster2
This example shows how to set up a single-node JupyterHub server: ElastiCluster will provision a virtual machine, install Jupyter/IPython and configure the JupyterHub server to run as a service over the default HTTPS website. (By default, a self-signed TLS/SSL certificate is used for HTTPS.)
