I'm so over setting up Jenkins servers. This repo contains everything you need to create a Jenkins AMI using Packer. Then you just start using that AMI. So easy.
You already have Berkshelf and Packer installed, right? Nice.
Make sure you have the AWS CLI installed and configured.
You'll also need to have a subnet and security group in which instances will be launched.
Run to build a new Jenkins AMI:
./packer-build.sh sg-XXXXXXXX subnet-YYYYYYYY
And then go do some real work.
If you're going to develop this cookbook, install Test Kitchen, and set the following environment variables:
export TOPHAT_SG=sg-XXXXXXXX
export TOPHAT_SUBNET_ID=subnet-YYYYYYYY
export TOPHAT_EC2_KEY=my_ec2_key_name
.kitchen.yml looks for those variables when provisioning a new instance.
