      Description

      currently, when we want to upgrade a slider app, each containers should be restarted manually.
      this makes upgrading very inconvenient.

      I propose the AutoRollingUpgrader.

      • the AutoRollingUpgrader is a thread running periodically.
      • if container’s appVersion is different from that Slider-AM know, the container will be restarted.
      • to avoid application down, container should be restarted one at a time.
      • configurations should be added as follows
        site.global.auto_rolling_upgrade_enabled: if this is set to true, the AutoRollingUpgrader is enabled.
        site.global.auto_rolling_upgrade_interval: the interval in milliseconds at which the AutoRollingUpgrader runs.

      upgrade scenario when the AutoRollingUpgrader is enabled

      1. user write a new appConfig file including changed “site.global.app_version"
      2. user execute "slider upgrade" command with new appConfig.
      3. slider-AM is killed and new slider-AM is launched with new appConfig.
      4. new Slider-AM reregister with previous containers.
      5. containers that have old appVersion are restarted by the AutoRollingUpgrader.

      a user want to upgrade only need to do 1,2.
