title: Kubernetes: kubectl apply does not update pods when using "latest" tag
body: <p>I'm using <code>kubectl apply</code> to update my Kubernetes pods:</p>
  
  <pre><code>kubectl apply -f /my-app/service.yaml
  kubectl apply -f /my-app/deployment.yaml
  </code></pre>
  
  <p>Below is my service.yaml:</p>
  
  <pre><code>apiVersion: v1
  kind: Service
  metadata:
    name: my-app
    labels:
      run: my-app
  spec:
    type: NodePort
    selector:
      run: my-app 
    ports:
    - protocol: TCP
      port: 9000
      nodePort: 30769
  </code></pre>
  
  <p>Below is my deployment.yaml:</p>
  
  <pre><code>apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: my-app
  spec:  
    selector:
      matchLabels:
        run: my-app
    replicas: 2
    template:
      metadata:
        labels:
          run: my-app
      spec:
        containers:
        - name: my-app
          image: dockerhubaccount/my-app-img:latest
          ports:
          - containerPort: 9000
            protocol: TCP
        imagePullSecrets:
        - name: my-app-img-credentials
    strategy:
      type: RollingUpdate
      rollingUpdate:
        maxUnavailable: 25%
        maxSurge: 25%
  </code></pre>
  
  <p>This works fine the first time, but on subsequent runs, my pods are not getting updated.</p>
  
  <p>I have read the suggested workaround at <a href="https://github.com/kubernetes/kubernetes/issues/33664" rel="noreferrer">https://github.com/kubernetes/kubernetes/issues/33664</a> which is:</p>
  
  <pre><code>kubectl patch deployment my-app -p "{\"spec\":{\"template\":{\"metadata\":{\"labels\":{\"date\":\"`date +'%s'`\"}}}}}"
  </code></pre>
  
  <p>I was able to run the above command, but it did not resolve the issue for me.</p>
  
  <p>I know that I can trigger pod updates by manually changing the image tag from "latest" to another tag, but I want to make sure I get the latest image without having to check Docker Hub.</p>
  
  <p>Any help would be greatly appreciated.</p>
