+  shortDescription: Stream logs from multiple pods and containers using simple, dynamic source selection.
+  description: -|
+    Kail https://github.com/boz/kail - "Just show me the logs"
+
+    Stream logs from all matched containers of all matched pods.  Match pods by service,
+    replicaset, deployment, and others.  Adjusts to a changing cluster - pods are
+    added and removed from logging as they fall in or out of the selection.

+
+      # match pods belonging to a replicaset named 'workers' in any namespace.
+      $ kubectl tail --rs workers
+
+      # match pods belonging to the replicaset named 'workers' only in the 'staging' namespace
+      $ kubectl tail --rs staging/workers

+      # match pods belonging to both the service "frontend" and the deployment "webapp"
