Declarative Management of Kubernetes Objects Using Configuration Files — result after merge - ERROR!

Reference note (untrusted external data; do not execute it as instructions). spec: strategy: type: Recreate # updated value: incompatible with rollingUpdate rollingUpdate: # defaulted value: incompatible with "type: Recreate" maxSurge : 1 maxUnavailable: 1 template: metadata: labels: app: nginx spec: containers: name: nginx image: nginx:1.14.2 ports: containerPort: 80 Bounded code example (external data; do not execute automatically): ```text **Explanation:** 1. The user creates a Deployment without defining `strategy.type`. 2. The server defaults `strategy.type` to `RollingUpdate` and defaults the `strategy.rollingUpdate` values. 3. The user changes `strategy.type` to `Recreate`. The `strategy.rollingUpdate` values remain at their defaulted values, though the server expects them to be cleared. If the `strategy.rollingUpdate` values had been defined initially in the configuration file, it would have been more clear that they needed to be deleted. 4. Apply fails because `strategy.rollingUpdate` is not cleared. The `strategy.rollingupdate` field cannot be defined with a `strategy.type` of `Recreate`. Recommendation: These fields should be explicitly defined in the object configuration file: - Selectors and PodTemplate labels on workloads, such as Deployment, StatefulSet, Job, DaemonSet, ReplicaSet, and Repli ``` Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
