title: Docker base image update in Kubernetes deployment
body: <p>We have a base image with the tag latest. This base image is being used for bunch of applications. There might be some update on the base image like ( OS upgrade, ...).</p>
  
  <p>Do we need to rebuild and redeploy all applications when there is a change in the base image? Or, since the tag is latest and the new base image also will be with the tag latest, it will be updating in the docker layer and will be taken care without a restart? </p>
