          ports:
            - containerPort: 8080

查看

status:
  availableReplicas: 1
  conditions:
  - lastTransitionTime: "2021-04-01T15:42:33Z"
    lastUpdateTime: "2021-04-01T15:42:33Z"
    message: Deployment has minimum availability.
    reason: MinimumReplicasAvailable
    status: "True"
    type: Available
  - lastTransitionTime: "2021-04-01T15:42:30Z"
    lastUpdateTime: "2021-04-01T15:42:33Z"
    message: ReplicaSet "spring-k8s-79f74b55d7" has successfully progressed.
    reason: NewReplicaSetAvailable
    status: "True"
    type: Progressing

一个条件是达到最小的可用副本数就变为 True，另一个是新的 rs 可用了就变为 True。
