Configure Serf Roles and adding Handlers

Using User data we can setup the Serf role:

ec2-run-instances --key your-key -g security-group --user-data-file user-data-file/master your-ami --region us-west-2
ec2-run-instances --key your-key -g security-group --user-data-file user-data-file/route your-ami --region us-west-2
ec2-run-instances --key your-key -g security-group --user-data-file user-data-file/build your-ami --region us-west-2
ec2-run-instances --key your-key -g security-group --user-data-file user-data-file/serve your-ami --region us-west-2

This repo pulls example handlers from darron/serf-docker-events - it could be any handlers at all.

Configurable Event Handlers

Inside /etc/default/serf you can configure an EVENTS_DIR that contains all of your handlers.

You can also configure an alternate SUFFIX if you prefer to write your handlers in a language other than Bash/sh.

If that EVENTS_DIR exists the serf.conf Upstart script will look for files ending in SUFFIX and add them as event handlers.

TODO

Better error checking, etc.
