title: How to get container's disk usage in Kubernetes (without docker command)?
body: <p>I have a Kubernetes Cluster and want to know how much disk space my containers use. I am not talking about mounted Volumes.</p>
  
  <p>I can get this information by using docker commands like <code>docker system df -v</code> or <code>docker ps -s</code>, but I don't want to connect to every single worker node.</p>
  
  <p>Is there a way to get a container's disk usage via <code>kubectl</code> or are there kubelet metrics where I can get this information from?</p>
