zookeeper-ansible

An ansible playbook for deploying a Zookeeper cluster to AWS. Typical workflow is to create an Amazon AMI using Packer and Ansible.

Getting Started

Copy vars.sh.example to vars.sh.

vars.sh contains private variables like AWS identifiers and key names. There are two sections to this file. One for the build stage and one for the deploy stage. Build variables are used when creating the AMI. Deploy variables are used when deploying the built AMI to AWS.

The file vars.yml contains additional variables you can set to control how the image is built. Variables here are non-private.

Build an AMI

AMIs are built using Packer. Packer will launch an EC2 instance, run the Ansible provisioning script and package an AMI.

make build-ami

Deploy an AMI

To deploy a built AMI to EC2, edit vars.sh with the configuration of where you want to deploy your AMI.

make <ami> deploy-ami

Provisioning Existing Servers

To provision or update existing servers on EC2, the servers must have AWS tags of Service:Zookeeper.

make provision
