<p>what is the meaning for "<strong>status:</strong>" in the kubernetes manifest file</p>

<pre><code>spec:
  type: LoadBalancer
  ports:
  - name: "7000"
    port: 7000
    targetPort: 80
  selector:
    io.kompose.service: ams-app
status:
  loadBalancer: {}
</code></pre>

<p>See "<a href="https://kubernetes.io/docs/concepts/overview/working-with-objects/kubernetes-objects/#object-spec-and-status" rel="nofollow noreferrer">Object Spec and Status</a>"</p>

<blockquote>
  <p>Every Kubernetes object includes two nested object fields that govern the object’s configuration: the object spec and the object status. </p>
  
  <ul>
  <li>The spec, which you must provide, describes your desired state for the object–the characteristics that you want the object to have. </li>
  <li><strong>The status describes the actual state of the object, and is supplied and updated by the Kubernetes system</strong>.  </li>
  </ul>
  
  <p>At any given time, the Kubernetes Control Plane actively manages an object’s actual state to match the desired state you supplied.</p>
</blockquote>

<p>So:</p>

<blockquote>
  <p>For example, a <a href="https://kubernetes.io/docs/concepts/workloads/controllers/deployment/" rel="nofollow noreferrer">Kubernetes Deployment</a> is an object that can represent an application running on your cluster.<br>
  When you create the Deployment, you might set the Deployment spec to specify that you want three replicas of the application to be running.<br>
  The Kubernetes system reads the Deployment spec and starts three instances of your desired application–<strong>updating the status to match your spec</strong>.<br>
  If any of those instances should fail (a status change), the Kubernetes system responds to the difference between spec and status by making a correction–in this case, starting a replacement instance.</p>
</blockquote>

<p>In your case, what you mention matches the publication of a <a href="https://kubernetes.io/docs/concepts/services-networking/service/" rel="nofollow noreferrer">Service</a> of type <a href="https://kubernetes.io/docs/concepts/services-networking/service/#type-loadbalancer" rel="nofollow noreferrer">LoadBalancer</a>.</p>

<blockquote>
  <p>The actual creation of the load balancer happens asynchronously, and information about the provisioned balancer will be published in the Service’s <strong><code>status.loadBalancer</code></strong> field.<br>
  For example:</p>
</blockquote>

<pre><code>kind: Service
apiVersion: v1
metadata:
  name: my-service
spec:
  selector:
    app: MyApp
  ports:
  - protocol: TCP
    port: 80
    targetPort: 9376
  clusterIP: 10.0.171.239
  loadBalancerIP: 78.11.24.19
  type: LoadBalancer
status:
  loadBalancer:
    ingress:
    - ip: 146.148.47.155
</code></pre>
