com.yahoo.vespa.config.server.ConfigServerBootstrap

All Implemented Interfaces:

com.yahoo.component.Component, com.yahoo.component.Deconstructable, Comparable<com.yahoo.component.Component>, Runnable

public class ConfigServerBootstrap
extends com.yahoo.component.AbstractComponent
implements Runnable

Main component that bootstraps and starts config server threads. Starts RPC server without allowing config requests. If config server has been upgraded to a new version since the last time it was running it will redeploy all applications. If that is done successfully the RPC server will start allowing config requests and the health status code will change from 'initializing' to 'up'. If VIP status mode is VIP_STATUS_PROGRAMMATICALLY the config server will be put into rotation (start serving status.html with 200 OK), if the mode is VIP_STATUS_FILE a VIP status file is created or removed by some external program based on the health status code.
