KyleAnderson/nerve — version 0.0.6 Dec 10th 2015
#nerve
##Overview
This puppet module installs and configures Nerve as part of Airbnb's SmartStack.
It allows you to dynamically register services in Zookeeper. See also Puppet-Synapse to configure the Synapse side of SmartStack: a local HAproxy that allows your services to find other services registered in zookeeper, by only needing to connect to localhost.
##Installation
puppet module install KyleAnderson/nerve
# Or librarian-puppet, r10k, whatever
##Usage
Default settings ensure present, and use system packages:
include nerve
Use gem install:
class { 'nerve':
package_provider => 'gem'
}
Use system packages, latest, but not running:
class { 'nerve':
package_ensure => 'latest',
service_ensure => 'stopped',
}
See init.pp or params.pp for more fields you can override. You can do things like:
- instance_id (defaults to $::fqdn)
- config_file (defaults to /etc/nerve/nerve.conf.json)
- config_dir (defaults to /etc/nerve/conf.d/)
- etc.
Registering Services
These are the defaults (Everything optional except for port):
nerve::register { 'service1':
port => '3000',
target => '/etc/nerve/conf.d/service1.json',
host => '127.0.0.1',
zk_hosts => ["localhost:2181"],
zk_path => "/nerve/services/service1",
check_interval => '2',
checks => [
{
'type' => 'http',
'uri' => '/health',
'timeout' => '0.2',
'rise' => '3',
'fall' => '2'
}
],
}
zk_hosts is an array of strings. Checks is an array of hashes.
##Limitations
The OS support assumes that rubygem-nerve is available or gem install nerve
is functioning. (depending on the provider you specify)
