Examples with D2Config com.linkedin.d2.discovery.util.D2Config used on opensource projects

Example 1 with D2Config

use of com.linkedin.d2.discovery.util.D2Config in project rest.li by linkedin.

the class ConfigRunner method main.

public static void main(String[] args) throws Exception {
    //get server configuration
    String path = new File(new File(".").getAbsolutePath()).getCanonicalPath() + "/src/main/d2Config/d2Config.json";
    JSONParser parser = new JSONParser();
    Object object = parser.parse(new FileReader(path));
    JSONObject json = (JSONObject) object;
    System.out.println("Finished parsing d2 topology config");
    String zkConnectString = (String) json.get("zkConnectString");
    int zkSessionTimeout = ((Long) json.get("zkSessionTimeout")).intValue();
    String zkBasePath = (String) json.get("zkBasePath");
    int zkRetryLimit = ((Long) json.get("zkRetryLimit")).intValue();
    Map<String, Object> serviceDefaults = (Map<String, Object>) json.get("defaultServiceProperties");
    //this contains the topology of our system
    Map<String, Object> clusterServiceConfigurations = (Map<String, Object>) json.get("d2Clusters");
    // 'comment' has no special meaning in json...
    clusterServiceConfigurations.remove("comment");
    System.out.println("Populating zookeeper with d2 configuration");
    //d2Config is the utility class for populating zookeeper with our topology
    //some the params are not needed for this simple example so we will just use
    //default value by passing an empty map
    D2Config d2Config = new D2Config(zkConnectString, zkSessionTimeout, zkBasePath, zkSessionTimeout, zkRetryLimit, (Map<String, Object>) Collections.EMPTY_MAP, serviceDefaults, clusterServiceConfigurations, (Map<String, Object>) Collections.EMPTY_MAP, (Map<String, Object>) Collections.EMPTY_MAP);
    //populate zookeeper
    d2Config.configure();
    System.out.println("Finished populating zookeeper with d2 configuration");
}
