create Deployment Beta resources after upgrading to 1.2. Not deleting the
Deployment objects may cause the deployment controller to mistakenly match
other pods and delete them, due to the selector API change.
     * Client (kubectl) and server versions must match (both 1.1 or both 1.2) for any
Deployment-related operations.
     * Behavior change:
        * Deployment creates ReplicaSets instead of ReplicationControllers.

  # Validate all yaml files under samples/bookinfo/networking directory
  istioctl validate -f samples/bookinfo/networking

  # Validate current deployments under 'default' namespace within the cluster
  kubectl get deployments -o yaml | istioctl validate -f -

  # Validate current services under 'default' namespace within the cluster
  kubectl get services -o yaml | istioctl validate -f -

- For deployments that installed the MinIO server binary by hand, use [`mc admin update`](https://min.io/docs/minio/linux/reference/minio-mc-admin/mc-admin-update.html)

```sh
mc admin update <minio alias, e.g., myminio>
```

Now that we know the difference between the terms **process** and **program**, let's continue talking about deployments.

## Running on Startup

## Cluster Replication Metrics

Metrics marked as ``Site Replication Only`` only populate on deployments with [Site Replication](https://min.io/docs/minio/linux/operations/install-deploy-manage/multi-site-replication.html) configurations.
