cfer-consul-cluster-cookbook

Uses Cfer to launch a self-bootstrapping Consul cluster into an AWS AutoScaling group.

To launch the cluster, run rake converge. This will prompt you for:

• A VPC ID
• A comma-separated list of Subnet IDs
• An EC2 Keypair name

Review and modify consul.rb before using this in production. I recommend also creating a wrapper cookbook to add your own server monitoring, log aggreagation, and other such infrastructure to these servers.

Features

• New nodes automatically join the cluster.
• Autoscaling policies roll over servers one at a time when changing things like instance type.
• CloudFormation creation and updates will fail and roll back if there's a provisioning issue.
