Tools for working with nerve. This repo builds as a dh_virtualenv package, and provides three entry points:
Determines the list of services running on the local box (scheduled by Paasta or manually configured), writes out a nerve config, and restarts nerve.
De-register a service. Tells hacheck to fail healthchecks for a service, and waits until the deregistration has propagated to the local synapse.
Clean up orphaned ZK nodes left by nerve.
This package uses environment_tools to reason about location hierarchies;
you must have a location_types.json and location_mapping.json describing your environments.
You will also need zookeeper topology files, at /nail/etc/zookeeper_discovery/infrastructure/{superregion}.yaml.
This must parse as a list of servers; each server is represented as a list of [hostname, port].
For example:
---
- ["hostname1", 2181]
- ["hostname2", 2181]
- ["hostname3", 2181]
