title: Kubernetes how to make Deployment to update image
body: <p>I do have deployment with single pod, with my custom docker image like:</p>
  
  <pre><code>containers:
    - name: mycontainer
      image: myimage:latest
  </code></pre>
  
  <p>During development I want to push new latest version and make Deployment updated.
  Can't find how to do that, without explicitly defining tag/version and increment it for each build, and do</p>
  
  <pre><code>kubectl set image deployment/my-deployment mycontainer=myimage:1.9.1
  </code></pre>
