zookeeper example

This simple example demonstrates how to use the zookeeper addon to tesla-microservice.

Running zookeeper

For testing you can run zookeeper locally.

1. Download from zookeeper.apache.org and unpack
2. start with bin/zkServer.sh
3. connect with bin/zkCli.sh
4. create some data under the path /foo with create /foo bar.

Running the example

1. Clone the repo.
2. If you are running zookeeper locally, resources/default.properties already has a valid connection string: zookeeper.connect=localhost:2181 you can override it with an environment variable: ZOOKEEPER_CONNECT=localhost:2182.
3. Start the application with lein run.
4. Access the example service under http://localhost:8080/example and http://localhost:8080/example/foo. The latter will report which data, if any, zookeeper has for the path /foo.
5. In bin/zkCli.sh try changing the data with set /foo baz and reload the page.
