    ...

    rollout:
      replicas: 2
      stepWeight: 50
      interval: "10s"

Name	Description	Type	Required	Default
interval	Schedule interval time	string	true	30s
stepWeight	Weight percent of every step in rolling update	int	true	50
replicas	Total replicas of the workload	int	true	2

Conflicts With

`Autoscale`

When Rollout and Autoscle traits are attached to the same service, they two will fight over the number of instances during rollout. Thus, it's by design that Rollout will take over replicas control (specified by .replicas field) during rollout.

Note: in up coming releases, KubeVela will introduce a separate section in Appfile to define release phase configurations such as Rollout.
