RDerby
rolling restarts using HAProxy, ndm, and some elbow grease.
Usage
rderby roll newww:8080 newww-1:8081 newww-2:8082
How does it work?
- the server is removed from HAProxy using the HAProxy API.
- ndm is used to restart the service.
- we wait for the service's port to start serving 200s.
- the server is added back to HAProxy.
