This library enables to use ZooKeeper as cluster coordinator in a ConstructR based node.
ConstructR aims at cluster bootstrapping (construction) by using a coordination service and provides etcd as the default one. By means of this library, you will be able to use ZooKeeper as coordination service instead.
- SBT
-
You will need to add the following dependency in your
build.sbt
in addition to the core ConstructR ones:libraryDependencies += "com.lightbend.constructr" %% "constructr-coordination-zookeeper" % "0.4.0"
- Gradle
-
Add following to
build.gradle
.Scala 2.11compile 'com.lightbend.constructr:constructr-coordination-zookeeper_2.11:0.4.0'
Scala 2.12compile 'com.lightbend.constructr:constructr-coordination-zookeeper_2.12:0.4.0'
Check this section in ConstructR for general information about configuration.
Check reference.conf for ZooKeeper related configuration.
The default configuration tries to establish a connection to ZooKeeper on localhost:2181
.
Override the constructr.coordination.nodes
configuration to specify another ZooKeeper node:
constructr.coordination.nodes = ["10.10.10.10:2181"]
The format per node ip:port
.
You are also able to connect to a multi-node cluster by specifying multiple nodes, separated by a comma:
constructr.coordination.nodes = ["10.10.10.10:2181", "10.10.10.11:2181", "10.10.10.12:2181"]
Additionally, comma separated connection string format is supported
constructr.coordination.nodes = "10.10.10.10:2181,10.10.10.11:2181,10.10.10.12:2181"
