Ness Computing Discovery Service

This is the service discovery system for the ness computing platform. It generally is deployed as a Galaxy tarball and provides service discovery for the rest of the platform.

Configuration

In galaxy, a three level (environment, deployment, service) configuration is used. The environment configuration is used to locate all the discovery servers and configure platform wide defaults.

environment configuration for development

For development, a single discovery server can be used.

ness.zookeeper.clientPort=21052
ness.zookeeper.clientPortAddress=127.0.0.1
#
ness.zookeeper.server.1=127.0.0.1:21050:21051
#
# Discovery Service
#
ness.discovery.enabled=true
ness.discovery.root=/ness/srvc/development
ness.discovery.scan-interval=120s
ness.discovery.tick-interval=100ms
ness.discovery.zookeeper-timeout=500ms
ness.discovery.penalty-time=600s

environment configuration for production

For a real environment, at least three servers should be present.

# ########################################################################
#
# Discovery configuration. Do not modify.
#
ness.zookeeper.clientPort=18700
#
ness.zookeeper.server.1=10.1.1.1:28990:28991
ness.zookeeper.server.2=10.2.2.2:28990:28991
ness.zookeeper.server.3=10.3.3.3:28990:28991
#
# Discovery Service
#
ness.discovery.enabled=true
ness.discovery.root=/ness/srvc/production
ness.discovery.scan-interval=120s
ness.discovery.tick-interval=100ms
ness.discovery.zookeeper-timeout=500ms
ness.discovery.penalty-time=600s
ness.discovery.http-port=8090

service specific (discovery service) configuration

This is the service specific configuration for a discovery server.

ness.zookeeper.dataDir=/home/henning/galaxy/deploy/persist/#{env.agent_group}/#{env.agent_id}/discovery
ness.zookeeper.tickTime=15000
ness.zookeeper.initLimit=5
ness.zookeeper.syncLimit=2
ness.zookeeper.maxClientCnxns=100
#
# Quartz Configuration
org.quartz.scheduler.instanceName = DiscoveryServiceScheduler
org.quartz.threadPool.threadCount = 5
#
# enable cleanup job
ness.job.zookeeper-cleanup.enabled=true
