title: Kubernetes not updates Docker image on redeployment
body: <p>Automation builds Docker image with microservice and push this image into JFrog Artifactory registry labeled by branch name <code>registry/service-name:branch</code>. At the next step it applies Kubernetes yaml manifest file and application starts after pulling image at the appropriate Kubernetes node.
  The problem is following - when I push changes in microservice source code into repository the automation starts:</p>
  
  <ul>
  <li>rebuild the project and push updated docker image into registry with the same label(branch)</li>
  <li>redeploy the microservice in Kubernetes</li>
  <li>microservice redeployed but with old image</li>
  </ul>
  
  <p>I guess it is occurs because there are no changes in 'Deployment' section of Kubernetes yaml manifest file and Kubernetes not pull updated image from JFrog registry. As workaround, I implement inserting timestamp annotation into template section on each redeployment:</p>
  
  <pre><code>  "template": {
        "metadata": {
            "labels": {
                "app": "service-name"
            },
            "annotations": {
                "timestamp": "1588246422"
  </code></pre>
  
  <p>But miracle is not happened - image updated only when I delete Kubernetes deployment and redeploy the application (may be in this case it just starts at the another node and docker pull is necessary).</p>
  
  <p>Is it possible to setup Kubernetes or configure manifest file some how to force Kubernetes pull image on each redeployment? </p>
