Vault updates no longer incurs up to (10 Seconds * instance count in the ASG) of downtime during deploys.

  • Configured the Vault health check to report standby nodes as healthy so all instances get registered as healthy to the ELB.
  • Configured the Vault Security Group to allow request forwarding that was introduced since the initial release of Cerberus to work properly with new ELB configuration

To enable this run run the following commands

cerberus -e xxxx -r yyyy update-stack --stack-name base --overwrite-template --owner-group foo
cerberus -e xxxx -r yyyy update-stack --stack-name vault --overwrite-template --owner-group foo

A bonus side effect of these changes, under high load the ELB doesn't freak out and drop the leader returning 503s.
