Setup and manage a toil and Apache Mesos cluster in EC2

Project description

The CGCloud plugin for Toil lets you setup a fully configured Toil/Mesos cluster in EC2 in just minutes, regardless of the number of nodes.

Prerequisites

The cgcloud-toil package requires that the cgcloud-core package and its prerequisites are present.

Installation

Read the entire section before pasting any commands and ensure that all prerequisites are installed. It is recommended to install this plugin into the virtualenv you created for CGCloud:

source ~/cgcloud/bin/activate
pip install cgcloud-toil

If you get DistributionNotFound: No distributions matching the version for cgcloud-toil, try running pip install --pre cgcloud-toil.

Be sure to configure cgcloud-core before proceeding.

Configuration

Modify your .profile or .bash_profile by adding the following line:

export CGCLOUD_PLUGINS="cgcloud.toil:$CGCLOUD_PLUGINS"

Login and out (or, on OS X, start a new Terminal tab/window).

Verify the installation by running:

cgcloud list-roles

The output should include the toil-box role.

Usage

Create a single t2.micro box to serve as the template for the cluster nodes:

cgcloud create -IT toil-box

The I option stops the box once it is fully set up and takes an image (AMI) of it. The T option terminates the box after that.

Substitute toil-latest-box for toil-box if you want to use the latest unstable release of Toil.

Now create a cluster by booting a leader and the workers from that AMI:

cgcloud create-cluster toil -s 2 -t m3.large

This will launch a leader and two workers using the m3.large instance type.

SSH into the leader:

cgcloud ssh toil-leader

… or the first worker:

cgcloud ssh -o 0 toil-worker

… or the second worker:

cgcloud ssh -o 1 toil-worker
