What it does

• Group of Pods as a unit. Supports a tightly managed group of pods that represent a “super pod”
• Dual-template, one for leader and one for the workers: A replica is a group of a single leader and a set of workers, and allow to specify a template for the workers and optionally use a second one for the leader pod.
• Multiple groups with identical specifications. Supports creating multiple “replicas” of the above mentioned group. Each group is a single unit for rolling update, scaling, and maps to a single exclusive topology for placement.
• A scale subresource. A scale endpoint is exposed for HPA to dynamically scale the number replicas (aka number of groups)
• Rollout and Rolling update. Supports performing rollout and rolling update at the group level, which means the groups are upgraded one by one as a unit (i.e. the pods within a group are updated together).
