+Subject: [PATCH] Fix --docker flag default for Click >= 8.2 compatibility
+
+Click 8.2 changed flag_value option handling: default=False is no longer
+normalised to None before the 'is None' guard. Change to default=None so
+sky launch works with Click >= 8.2 (e.g. nixpkgs).
+
+Upstream constrains click<8.2; this makes the code robust to newer versions.
