Hello everyone!
I am wondering if anyone in the DevOps community knows of a good way to manage Zookeeper instances in an autoscaling group on Amazon AWS... here's some background.
I am using puppet to manage the instances, with a custom fact based on a tag to set a 'role', using the roles and profiles pattern.
The zookeeper configuration file needs to know about all of the other instances available. Should I use a script run on the master (with the generate function) to pull down a list of EC2s in that scaling group using the aws command? Custom fact on the box (using a similar command)?
I did see a serverfault post on using puppetDB. We haven't used puppetdb yet in our environment, and due to security policies, it takes a while to add new software to our environment.
Does anyone have any other suggestions for managing the zookeeper config's list of servers?
