title: How to know to upgrade my pod when a container is updated?
body: <p>I have a pod with 3 containers (ca, cb, cc).</p>
  <p>This container is owned by TeamA. Team A creates and owns ca.the other two containers are developed by two other teams. TeamB for cb and TeamC for cc.</p>
  <p>Both cb and cc also run independently (outside the TeamA pod) as services within this same cluster.</p>
  <p>How can TeamA pod find out when cb or cc deploy a newer version in the cluster and how can we ensure that it triggers a refresh?</p>
  <p>As you may have guesses cb and cc are services that ca relies on heavily and they are also services in their own right.</p>
  <p>Is there a way to ensure that TeamA pod keeps cb and cc updated whenever TeamB and TeamC deploy new versions to the cluster?</p>
