Class RebootScheduler

java.lang.Object
  org.gcube.common.vremanagement.deployer.impl.operators.common.BaseScheduler
      org.gcube.common.vremanagement.deployer.impl.operators.common.RebootScheduler

All Implemented Interfaces:

Scheduler

public class RebootScheduler
extends BaseScheduler

Scheduler to execute the packages' reboot scripts.
These script are meant to prepare the environment for the package that brings each of them. Therefore, they must be executed from an external process, immediately before the gContainer process is going to start. The scheduler serializes the list of packages on this file: ServiceContext.getContext().getFile("reboot_scripts") It is expected that the gcore-start-container-* scripts take care of this list by executing them before to start the gContainer itself.
