synapse-tools
Tools for working with synapse. This repo builds as a dh_virtualenv package, and provides three entry points:
configure_synapse
Creates a Synapse configuration and restarts Synapse when the config changes.
haproxy_synapse_reaper
Kills old HAProxy processes that are handling long-lived connections. When HAProxy is reloaded, the old process sticks around until all its connections terminate. Some protocols have connections that last a long time or indefinitely, leading to a buildup of HAProxy processes. This script cleans those up.
synapse_qdisc_tool
Manages the plug queueing discipline to prevent connections from being dropped while reloading HAProxy. See the help text for more info.
Configuration
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]
