title: How can I check how many instances of a Google Cloud Run container are running?
body: <p>Google Cloud Run lets me set a <em>concurrency</em> for a given container, which is how many concurrent requests it will service before a new container is spun up.</p>
  
  <p>How do I actually check how many containers are running at any given time? The web interface mentions which services are running but not how many of them there are, and the same is true when I do <code>gcloud beta run services (list|describe)</code>.</p>
