runbook

This runbook for trying to figure out what is wrong with the devops-infra-demo stack if something goes wrong.

• Check the boot messages for an EC2 instance.
  • There could be a problem downloading and installing the CodeDeploy package, which happens through cloud-init
  • Maybe the packer-generated AMI that has been built is no longer supported by the AWS runtime. This happened when the c5 and m5 instances started requiring support for ENA and CentOS images lacked the right drivers in the kernel.
• Examine the load balancer health checks for the stack
• etc, etc. etc... this is just a demo runbook.
