Specific Upgrade of Shuffle Servers

If we want to upgrade shuffle servers by specifying replicas, we need to edit the rss object as follows:

• update .spec.shuffleServer.image with new image version of shuffle server
• set .spec.shuffleServer.sync field to true
• update .spec.shuffleServer.upgradeStrategy field:
  • set .spec.shuffleServer.upgradeStrategy.type to be SpecificUpgrade
  • update .spec.shuffleServer.upgradeStrategy.specificNames field, which means the pod name we want to upgrade

spec:
  shuffleServer:
    image: "${rss-shuffle-server-image}"
    sync: true
    upgradeStrategy:
      type: "SpecificUpgrade"
      specificNames: [ "rss-shuffle-server-demo-0" ]

We can refer to the example.
