| IMPORTANT: For {{es}} version 8.16 and later, set the `vm.max_map_count` kernel setting to `1048576`; for {{es}} version 8.15 and earlier, set `vm.max_map_count` to `262144`. The exception is in GKE Autopilot environments, where `vm.max_map_count` must always be set to `262144`. This is because any privileged DaemonSet in GKE Autopilot must match the DaemonSet pre-approved by Google. |
