+Step A3 - Do your nodes have enough disk space?
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+If your nodes are out of disk space, pulling the SkyPilot images may fail with :code:`rpc error: code = Canceled desc = failed to pull and unpack image: context canceled`.
+Make sure your nodes are not under disk pressure by checking :code:`Conditions` in :code:`kubectl describe nodes`, or by running:
